PERMANENT RULES

DEPARTMENT OF TRANSPORTATION


[ Filed January 28, 2005, 2:06 p.m. , effective February 28, 2005 ]


Purpose: Over time the rules of chapter 468-38 WAC have taken on a patchwork condition that includes some inconsistencies, ambiguities, techno-jargon and holes where office policy has been used to fill in where the rule did not provide adequate direction. The primary purpose of amending the rule is to crease a user-friendlier document that provides adequate direction for the administration and enforcement of federal and state vehicle size and weight parameters. The revision includes a complete rewrite of the chapter into a "question and answer" format. Sections with like content have been consolidated. Sections that merely restate law have been proposed for repeal. Where necessary, clarifying language has been added for better understanding. The revision also incorporates long-standing office policy into rule, and includes some negotiated rule changes.

Summary of Changes to Chapter 468-38 WAC:

General: All sections included in the proposal have been written in a "question and answer" format to enhance communications with stakeholders. Each subsection is addressed below regarding any additional changes.

Chapter 468-38 WAC, the title has been modified to more accurately reflect the chapter subject matter. The title "Vehicle size and weight -- Restricted highways -- Equipment" should be replaced with "Vehicle size and weight -- Highway restrictions -- Equipment."

Chapter 468-38 WAC

VEHICLE SIZE AND WEIGHT -- ((RESTRICTED)) HIGHWAY((S)) RESTRICTIONS -- EQUIPMENT


NEW SECTION
WAC 468-38-001   Purpose and scope.   What is the purpose and scope of this administrative code chapter for vehicle size and weight? (1) This chapter provides rules necessary for the implementation of certain sections of chapter 46.44 RCW, to include the issuance of special permits that allow vehicles, or combinations of vehicles, to move in a legal or extra-legal configuration on the public highways. The chapter also includes rules on safety and operations as they relate to the permitting of extra-legal configurations.

(2) The chapter avoids, where possible, the restating of revised code and therefore should be used in conjunction with the revised code.

(3) The chapter has been written in a "question and answer" format to enhance communication with users.

[]


NEW SECTION
WAC 468-38-005   Definitions.   What vehicle size and weight words and phrases are used commonly in addition to those codified in chapter 46.04 RCW?

A-dolly: A converter dolly that is towed from a single hitch at the center line of the tow vehicle and contains the lower half of the fifth wheel assembly that when connected by kingpin to a semi-trailer converts the combined configuration into a full trailer.

A-train double: A combination of vehicles composed of a tractor, a semi-trailer and either an A-dolly and a semi-trailer or a full trailer attached to the rear of the forward semi-trailer as if an A-dolly were used.

Axle: The common axis of rotation of one or more wheels, either power-driven or freely rotating, in one or more segments in the same transverse plan. (Expanded from the definition in chapter 46.04.060 RCW.)

Axle group: Any set of two or more parallel axles associated with a single vehicle or vehicle combination.

Axle group weight: The part of the gross vehicle weight transmitted to the highway by the defined axle group.

Axle spacing (spread): The longitudinal distance between the centers of the foremost and rearmost axles of an axle group measured from center to center of the defined axles.

B-train double: A combination of vehicles composed of a tractor, a semi-trailer and a second semi-trailer connected by kingpin to the lower half of a fifth wheel assembly mounted on the rear of the forward semi-trailer.

C-dolly: A converter dolly that is equipped with a single axle that is self-steering, towed from two hitches located in a horizontal transverse line on the towing unit, and is so designed that when the trailer converter dolly is coupled to a towing trailer, the trailer converter dolly cannot pivot horizontally with respect to the towing trailer.

Axle spacing report: A report stating the maximum amount of weight a vehicle, or vehicle combination, can carry, both legally and under permit, based on the number of axles, the axle spacings, and the number and sizes of tires on the vehicle, or vehicle combination.

Combination length: The total length of a combination of vehicles, i.e., truck-tractor -- semi-trailer -- trailer combination, measured from front extremity of the first vehicle to the rear extremity of the last vehicle, including the connecting space between vehicles and any overhanging load.

Combined trailer length: The total length of a combination of trailers measured from the front extremity of the first trailer to the rear extremity of the last trailer including the connecting space and any overhanging load.

Converter dolly: A vehicle unit that is designed, usually with the bottom half of a fifth wheel assembly, to convert a semi-trailer with kingpin into a full trailer.

C-train double: A combination of vehicles composed of a tractor, a semi-trailer, a C-dolly and a second semi-trailer.

Daylight hours: One-half hour before sunrise until one-half hour after sunset.

Extra-legal vehicle: A vehicle, laden or unladen, which exceeds legal dimensions and/or weights and operates on highways by permit.

Gross weight: The weight of a vehicle and/or combination of vehicles plus the weight of any load thereon.

Height: The total vertical dimension of a vehicle above the ground surface including any load or appurtenance.

Length: The total longitudinal dimension of a single vehicle, vehicle combination (see combination length), or individual trailer or semi-trailer. Trailer length is measured from the front of the cargo-carrying unit to its rear, exclusive of all overhangs from safety or energy efficiency devices (see also measurement exclusive devices). Length of a loaded trailer must include any overhangs of load when determining compliance with length limits or the need for a special permit.

Longer combination vehicle: A combination of truck tractor, semi-trailer, and trailer that exceeds legal length dimensions and operates on highways by permit for transporting reducible loads.

Maximum off track: The maximum difference in the path created by the center of the steering axle and the center of the rearmost axle of the vehicle or vehicle combination during the negotiation of a turn.

Multilane highway: A highway with two or more lanes of travel in the same direction.

Measurement exclusive devices: Certain devices that provide added safety, energy conservation, or are otherwise necessary, and are not designed to carry cargo.

National network: Those interstate and other federal-aid primary highways on which commercial vehicles of the dimensions authorized by the Surface Transportation Assistance Act of 1982 are allowed to operate.

Night: Night means one-half hour after sunset to one-half hour before sunrise.

Nondivisible load: A load that cannot be readily or reasonably dismantled and is reduced to a minimum practical size and weight. Portions of a load can be detached and reloaded on the same hauling unit when the separate pieces are necessary to the operation of the machine or equipment which is being hauled: Provided, That the arrangement does not exceed permit limits for the configuration without the reloaded pieces. The federal definition of nondivisible load to be used for vehicles operating on the interstate is as follows: Any load or vehicle exceeding applicable length or weight limits that, if separated into smaller loads or vehicles, would: Compromise the intended use of the vehicle, destroy the value of the load or vehicle, require more than eight work hours to dismantle using appropriate equipment.

Permit: A written or electronic authorization to:

(a) Move or operate a vehicle, or combination of vehicles, on a highway;

(b) With or without a load;

(c) Of size and/or weight exceeding the limits prescribed for vehicles in regular operation.

Pilot/escort vehicle: A motor vehicle used for the express purpose as a warning and guide vehicle for extra-legal vehicles.

Pounds per inch of tire width: A measure of load restriction based on rated tire size. The pounds per inch of tire width are determined by dividing the weight carried on the axle group by the number of tires in the group and dividing again by the manufacturer's rated tire width as indicated on the sidewall of the tire.

Rear overhang: The distance from the center of the last axle to the end of the load, or portion of the vehicle whichever is longer.

Regional permit: Permits issued for interstate movement of certain nondivisible overweight and/or oversize vehicles and/or loads on highways designated by the jurisdictions participating in the "Western Regional Agreement for the Issuance of Permits for Overweight and/or Oversize Vehicles and/or Loads Involved in Interstate Travel."

Regular operation: The movement over highways of motor vehicles with dimensions and weights specified by state and federal codes.

Retractable axle: An axle that can be separately raised and lowered by the driver of the vehicle but may not have its weight bearing capacity regulated from within reach of the driver's compartment. Also known as "lift axle" and "booster axle," or more formally known as a "variable load suspension" (VLS) axle.

Rocky mountain double: A combination of vehicles including a truck-tractor pulling a long semi-trailer and a shorter trailer.

Single axle: An assembly of two or more wheels whose centers are in one transverse vertical plane and which are transmitting weight to the highway.

Single unit: A motor vehicle with no attached vehicles, i.e., truck, bus, truck-tractor.

Steering axle: The axle or axles on the front of a motor vehicle that are activated by the operator to directly accomplish guidance or steerage of the vehicle and/or a combination of vehicles.

Superload: A superload is any load that would require special analysis and approval by one or more state permit offices because of dimensions or weight. Criteria for superloads in Washington state are found in WAC 468-38-405.

Tandem axle: Any two consecutive single axles whose centers may be included between parallel transverse vertical planes spaced at least four feet but not more than eight feet apart, extending across the width of the vehicle, articulating from a common attachment, or designed to automatically equalize the load between the two axles. This working definition is extrapolated from RCW 46.44.041.

Tote: Common term for a motor vehicle used to transport manufactured housing.

Tridem axle: Any three consecutive single axles whose extreme centers may be included between parallel transverse vertical planes spaced not more than twelve feet apart, extending across the width of the vehicle, and are articulated from a common attachment to the vehicle, or are designed to automatically equalize the load between the three axles.

Truck-tractor: A motor vehicle used primarily for pulling other vehicles but not specifically constructed to carry a load other than a part of the weight of the vehicle and load being pulled. This vehicle may include a small freight compartment (also referred to as a dromedary box), deck or plate not more than eight feet in length used for carrying a load. Federal rule allows the interstate use of a vehicle with a dromedary box only if the vehicle was in operation prior to December 1, 1982, proof to be provided by the vehicle operator. This working definition was extrapolated from RCW 46.04.655, 46.44.037 and Code of Federal Regulation, 23 CFR 658.13(f).

Trunnion axle: An axle configuration with two individual axles mounted in the same transverse plane, with four tires on each axle, connected at a pivot point that allows each individual axle to oscillate in a vertical plane to provide constant and equal weight distribution on each individual axle.

Trunnion axle group: Two or more consecutive trunnion axles, that are individually attached to, and/or articulated from, the vehicle, and may include a weight equalizing suspension system.

Turnpike double: A combination of vehicles including a truck-tractor pulling a long semi-trailer and an additional long trailer.

Wide base tire: A tire whose nominal section (sidewall to sidewall) width, as identified by tire nomenclature, is over fourteen inches.

Width: The total outside transverse dimension of a vehicle including any load or load-holding devices thereon, but excluding approved safety devices and tire bulge due to load.

AMENDATORY SECTION(Amending Order 197, filed 5/9/00, effective 6/9/00)

WAC 468-38-070   Maximums and other criteria for special permits -- Nondivisible.   (1) ((Overwidth: 14 feet on any two-lane highway; 20 feet on any multiple-lane highway where a physical barrier serving as a median divider separates the oncoming and opposing traffic lanes; 32 feet on any multiple-lane undivided highway.

The regulations on movement of buildings are in WAC 468-38-360.

(2) Overheight: A load over 14 feet high must be moved by permit, but the permittee is to be governed by the clearance of overhead obstructions such as bridges, underpasses, wires, overhead signs and other objects. The issuance of a permit does not insure the route to be free of low overhead structures. It is the responsibility of the permittee to check the proposed route and detour when necessary. County or city road detours for this purpose require authorization from respective jurisdictions.

(3) Overlength: The permit will allow movement on routes on which the permittee can negotiate curves, interchanges, entrance and exit roadways and other obstacles. In all instances the general safety of the public is considered paramount.

(4) Loading restrictions: The load must be reduced to a practicable minimum, even if additional vehicles are required to transport the divided item. Loads created by welding, bolting or tying will be construed as divisible, unless proven with good cause not to be divisible.

(5) Overweight loads: Restricted to the limits established in RCW 46.44.091 Special permits -- Gross weight limit. In addition, tire loadings are limited to a maximum of six hundred pounds per inch width of tire.

(6) Allowable vehicle configurations:

(a) Tractor (or unladen truck) and semi-trailer or full trailer. Jeeps and/or boosters may be added to the trailer as necessary. Trailers in excess of the legal width of eight feet six inches, or legal length of fifty-three feet, or the permitted length of fifty-six feet, shall not exceed the length or width of the load, unless, the added dimension is necessary to spread the weight of load to comply with requirements established by the department to protect the infrastructure. A "pusher" power unit may be added to the configuration upon approval.

(b) Tractor with semi-trailer and full trailer. Combined trailer length, including space between trailers, may not exceed sixty-one feet. This combination is limited to nondivisible loads not to exceed ten feet wide. Both trailers may carry nondivisible loads with the widest load contained on the first trailer. This configuration may not carry over-height, over-length or over-weight loads.

(c) Truck and trailer. Combined overall length when carrying an over-length load may not exceed eighty-five feet, with the nondivisible over-length load restricted to the trailing unit, overhang loaded entirely to the rear of the trailer. An over-width or over-height nondivisible load may be carried on the truck and/or trailing unit. This configuration may not carry overweight loads.

(7) Loads with multiple pieces: An over-dimensional load may include multiple pieces, provided:

(a) The vehicle(s) and load are transported at legal weights.

(b) The largest nondivisible piece(s) must be loaded to its practicable minimum. No single piece may create a dimension greater than the dimension it would create if carried by itself.

(c) Additional pieces may not exceed the outside envelope (rectangular) dimension created by the largest piece(s) loaded in its smallest configuration. No piece shall be added to a load for the sole purpose of creating a larger envelope. It shall be the responsibility of the carrier to provide proof that all pieces are necessary to the move.)) Are there maximum dimensions established for moving nondivisible over-dimensional vehicles and/or loads? Yes. In all instances the general safety of the public is considered paramount and will ultimately govern over-dimensional moves. There are some general rules; however, physical barriers determine most maximums for over-dimensional moves. Over-dimensional maximums are addressed as follows:

(a) Overwidth: As stipulated in RCW 46.44.092, fourteen feet on any two-lane highway; twenty feet on any multiple-lane highway where a physical barrier serving as a median divider (i.e., jersey barrier, cyclone fence, guardrail, etc.) separates the oncoming and opposing traffic lanes; thirty-two feet on any multiple-lane undivided highway. Permits may be issued for widths in excess of the preceding limits when traveling on highway segments that by design can accommodate the greater width.

(b) Overheight: Any move involving height, especially permitted moves exceeding fourteen feet, are governed by the ability to clear overhead obstructions such as bridges, underpasses, wires, overhead signs, and other objects. The issuance of a permit does not insure the route to be free of overhead obstructions. It is the responsibility of the permit applicant to check, or prerun, the proposed route and provide for safe maneuvers around the obstruction or detours as necessary. Structures owned by the state should be reviewed with department field personnel to determine safe navigation of the move, including options for temporary removal of obstructions. Detours off the state route onto county or city roads require authorization from those jurisdictions. A traffic control plan (see WAC 468-38-405 (3)(d)) may be requested for approval by the department before a permit is issued.

(c) Overlength: Routes will be limited to over-dimensional moves based on ability to negotiate curves, interchanges, entrance and exit roadways and other obstacles.

(2) Are there maximum weights established for moving nondivisible overweight vehicles and/or loads? Yes. Weight maximums for the movement of a nondivisible load under special permit are established in RCW 46.44.091. In addition, tire loading for the movement of a nondivisible load is limited to the lesser of six hundred pounds per inch width of tire or the tire manufacturer's rating with proper inflation, as determined by the nomenclature imprinted on the tire.

(3) Are there maximums and/or other criteria established for the use of specific vehicle combinations when moving over-dimensional nondivisible loads? Yes. The maximums for specific vehicle combinations are as follows:

(a) Truck-tractor pulling a semi-trailer or full trailer: Trailers in excess of legal length and/or width dimensions, or the permitted length of fifty-six feet, shall not exceed the length or width of the nondivisible load being transported. The department may grant an exception when the added dimension is necessary to spread the weight of the load to comply with requirements established by the department to protect the infrastructure. Jeeps and/or boosters may be added to the trailer to help distribute weight as necessary. A "pusher" power unit may also be added to the configuration upon approval of the department. Jeeps, boosters and pusher power units will be considered part of the trailing unit plus load measurement.

(b) Truck-tractor pulling semi-trailer and full trailer (or two semi-trailers in B-train configuration): The combined trailer length, including the space between trailers, may not exceed sixty-one feet. This combination is limited to nondivisible loads not to exceed ten feet wide. Both trailers may carry a nondivisible load, with the widest load carried on the first trailer. Trailers in excess of legal width shall not exceed the width of the nondivisible load being transported. This combination may not carry overheight, overlength or overweight loads.

(c) Truck and trailer: There are two scenarios for this combination:

(i) Both truck and trailer carrying loads: The combined overall length of the combination when carrying a nondivisible overlength load must not exceed eighty-five feet. Any nondivisible overlength load is restricted to only one vehicle. The trailer may be loaded with the overhang entirely to the rear of the trailer, or the truck may be loaded with the overhang entirely to the front of the truck. Both truck and trailer may carry overwidth and overheight loads. The truck and/or trailer in this configuration may not carry an overweight nondivisible load.

(ii) Unladen truck and trailer: The unladen truck may be treated as a truck-tractor and the combination addressed as described in (a) of this subsection: Provided, That the truck-tractor is not carrying any load of any kind, and that its use as an unladen truck is specified on the special permit. The trailing unit is measured from the foremost point of the draw bar or load, whichever is greater, to the rearmost part of the trailer or load, whichever is greater. This combination may carry a nondivisible overweight load on the trailer. For example, an unladen dump truck may acquire a special permit to pull a tilt trailer with a dozer or backhoe where the trailer load causes the axles to exceed legal weight.

(4) Can a vehicle, or vehicle combination, carry multiple pieces when using an over-dimensional nondivisible special permit? Yes, under the following conditions:

(a) The vehicle(s) and load are transported at legal weights.

(b) The largest nondivisible piece(s) must be loaded to its practicable minimum. No single piece may create a dimension greater than the dimension it would create if loaded properly and carried by itself.

(c) Additional pieces may be added within the envelope dimension created by the largest piece(s) loaded to its practicable minimum. The envelope should be viewed as an imaginary cube with height, length and width defined by the extremities, regardless of shape, of the over-dimensional piece(s) and other legal dimensions as necessary. The department will provide an illustrative example upon request.

(5) Are there any circumstances when an over-dimensional vehicle(s) can move a legal size load? Yes, when the following conditions have been met:

(a) The vehicle(s) are making the move in conjunction with being in route to pick up a nondivisible load under special permit (front haul); or

(b) The vehicle(s) are making the move in conjunction with returning from a delivery of a nondivisible load under special permit (back haul); and

(c) The route traveled is the same route that would have been used if a legal load had not been moved; and

(d) The front haul or back haul is noted on the special permit used for the nondivisible move.

AMENDATORY SECTION(Amending Order 183, filed 10/13/98, effective 11/13/98)

WAC 468-38-071   Maximums and other criteria for special permits -- ((Reducible)) Divisible.   (1) ((Overlength: Permits for reducible loads shall not exceed 56 feet for a single trailer and 68 feet for double trailers. Measurement for a single trailer will be from the front of the trailer, or load, to the rear of the trailer, or load, whichever provides the greater distance up to 56 feet. Measurement for double trailers will be from the front of the first trailer, or load, to the rear of the second trailer, or load, whichever provides the greatest distance up to 68 feet. A log truck pulling a pole-trailer, trailer combination, carrying two distinct and separate loads will be treated as a tractor-semitrailer-trailer (doubles). Measurement for the log truck, pole-trailer, trailer combination will be from the front of the first bunk on the truck to the rear of the second trailer, or load, whichever provides the greatest distance up to 68 feet. Measurements shall not include nonload carrying devices designed for the safe and efficient operation of the semitrailer or trailer; for example: External refrigeration unit, resilient bumper, and aerodynamic shells.

(2) Overheight: A vehicle, or vehicle combination, hauling empty apple bins, or owned and operated by a rancher hauling hay from the rancher's own fields for use with the rancher's own livestock, may be issued a permit, for vehicle and load, not to exceed fifteen feet high, measured from a level road bed. This permit may be used in conjunction with the overlength permit described in subsection (1) of this section.)) Can a vehicle, or vehicle combination, acquire a permit to exceed the dimensions for legal vehicles in regular operation when moving items of a divisible nature? Yes. There are some very specific configurations that can receive extra length or extra height when carrying a divisible load.

(2) What configurations can be issued a permit, and how are they measured? The configurations and measurement criteria are:

(a) An overlength permit may be issued to a truck-tractor to pull a single trailer or semi-trailer, with a trailer length not to exceed fifty-six feet. The measurement for the single trailing unit will be from the front of the trailer (including draw bar when used), or load, to the rear of the trailer, or load, whichever provides the greater distance up to fifty-six feet. Rear overhang may not exceed fifteen feet.

(b) An overlength permit may be issued to a truck-tractor to pull a set of double trailers, composed of a semi-trailer and full trailer or second semi-trailer, with a combined trailer length not to exceed sixty-eight feet. The measurement for double trailers will be from the front of the first trailer, or load, to the end of the second trailer or load, whichever provides the greatest distance up to sixty-eight feet. Note: If the truck-tractor is carrying an allowable small freight compartment (dromedary box), the total combined length of the combination, combined trailer length notwithstanding, is limited to seventy-five feet.

(c) An overlength permit may be issued to a log truck pulling a pole-trailer, trailer combination, carrying two distinct and separate loads, as if it was a truck-tractor pulling a set of double trailers. Measurement for the log truck, pole-trailer, trailer combination will be from the front of the first bunk on the truck to the rear of the second trailer, or load, whichever provides the greatest distance up to sixty-eight feet.

(d) An overheight permit may be issued to a vehicle or vehicle combination, hauling empty apple bins, not to exceed fifteen feet high. Measurement is taken from a level roadbed. This permit may be used in conjunction with either of the overlength permits in (a) or (b) of this subsection. The permit may also provide an exemption from a front pilot/escort vehicle as required by WAC 468-38-100 (1)(h). The exemption does not limit the liability assumed by the permit applicant.

(e) An overheight permit may be issued to a vehicle or vehicle combination owned by a rancher and used to haul his own hay from his own fields to feed his own livestock, not to exceed fifteen feet high, measured from a level roadbed. This permit may be used in conjunction with either of the overlength permits in (a) or (b) of this subsection. The permit may also provide an exemption from a front pilot/escort vehicle as required by WAC 468-38-100 (1)(h). The exemption does not limit the liability assumed by the permit applicant.

(3) Are there any measurement exclusive devices related to these permits? Measurements should not include nonload-carrying devices designed for the safe and/or efficient operation of the vehicle, or vehicle combination components, for example: An external refrigeration unit, a resilient bumper, an aerodynamic shell, etc. Safety and efficiency appurtenances, such as, but not limited to, tarp rails and splash suppression devices, may not extend more than three inches beyond the width of a vehicle. The examples are not all inclusive.

(4) Are overweight permits available for divisible loads? The secretary of transportation, or designee, may issue permits to department vehicles used for the emergent preservation of public safety and/or the infrastructure (i.e., snow removal, sanding highways during emergency winter conditions, emergent debris removal or retainment, etc.). The permits will also be valid for the vehicles in transit to or from the emergent work site. The special permits may allow:

(a) Weight on axles in excess of what is allowed in RCW 46.44.041;

(b) Movement during hours of the day, or days of the week, that may be restricted in WAC 468-38-175;

(c) Exemption from the sign requirements of WAC 468-38-155(7) if weather conditions render such signs ineffectual; and

(d) Movement at night, that may be restricted by WAC 468-38-175(3), by vehicles with lights that meet the standards for emergency maintenance vehicles established by the commission on equipment.

RCW 47.48.031 and 46.44.080 provide authority for the chief or another officer of the state patrol, or the secretary of transportation or designee, to restrict vehicle movement by closing or restricting movement on a section(s) of state highway(s) to all vehicles or specific class of vehicles.

(2) Under what conditions would a road restriction be put in place? A restriction or closure may be put in place whenever the department or the state patrol believe that weather or other conditions have created a substantial risk to public safety.

(3) How are the restrictions maintained? The department and the state patrol shall exchange notices of conditions that require a restriction(s) or closure to be placed on the highway, and notices when conditions change that will allow the restriction to be terminated. Either the department or the state patrol, whichever agency can best respond to the condition, shall manually control traffic as needed until the restriction is terminated or until the department can install traffic control devices.

(4) How will the notification of a restriction be communicated to the highway users? The department and the state patrol have a joint responsibility to provide notice of both the placement and removal of highway restrictions/closures. Notices shall be provided to the news media, affected law enforcement agencies, and other appropriate organizations, both public and private. For areas requiring vehicles to apply tire chains, see subsection (8) of this section.

(5) At what point does visibility play a factor in the movement of a vehicle operating under special permit? Moves must not be made when visibility is reduced to one thousand feet or less. If visibility is reduced during transport, the vehicle or vehicle combination must clear the highway at the nearest safe location.

(6) Can an individual move under special permit be restricted through enforcement intervention? Yes. An enforcement officer, at his/her discretion, may require the driver of the permitted vehicle or vehicle combination to pull off of the highway when weather or other conditions become unsafe for further movement. The enforcement officer may direct or escort the permitted vehicle to a place of safety where it may be parked until the unsafe conditions abate.

(7) Do vehicles carrying hazardous or radioactive cargo have greater opportunity of being affected by restrictions? Yes. Due to the potential risks to the public, RCW 47.01.270 and 47.48.050 have provided the department and the state patrol with the specific authority to close a section(s) of the highway(s) to transporters of placarded radioactive or hazardous cargo. The basis for closure is the same as stated in subsection (2) of this section.

(8) Who has authority to prohibit permitted vehicles from chain/approved traction device control areas, and how is this communicated? The department and the state patrol may prohibit a vehicle, whether moving under special permit for oversize/overweight or not, from entering chain/approved traction device control areas. Prohibitions are put in place when it is determined the vehicle will experience difficulty in safely traveling the area. Traffic control signs will generally communicate prohibitions (i.e., "TRACTION ADVISORY/OVERSIZED VEHICLES PROHIBITED," "CHAINS REQUIRED ON ALL VEHICLES EXCEPT ALL WHEEL DRIVE," "VEHICLES OVER 10,000 GVWR CHAINS REQUIRED," etc.). In addition, specific vehicle combinations may be required to operate with specified traction devices (i.e., "TRACTORS PULLING DOUBLE TRAILERS MUST CHAIN UP"). Also, refer to WAC 204-24-050 (2)(h) for a list of areas where sufficient tire chains must be carried on the vehicle(s) between November 1 and April 1 of each year.

(9) What penalties are in place for vehicles moving in prohibited areas? Movement into a restricted area when the vehicle is prohibited, or without the specified traction device, is a violation of the special permit, which is a traffic infraction, and subject to the penalties of RCW 46.44.105.

(10) What responsibilities must the operator of a vehicle(s) operating under special permit, during winter road conditions, assume when signs or other traffic control devices are not present? A vehicle, or vehicle combination, operating under special permit for oversize, must stop movement at the nearest safe location during periods when:

(a) Snow is falling to a degree that visibility is limited to less than one thousand feet; or

(b) Immediately following a severe storm when snow removal equipment is operating; or

(c) When fog or rain limits visibility to less than one thousand feet; or

(d) When compact snow and ice conditions require the use of chains.

Movement must not resume until conditions have abated and clearance obtained from the nearest department or state patrol office. Failure to stop is a violation of the permit and subject to the penalties of RCW 46.44.105.

AMENDATORY SECTION(Amending Order 68, filed 11/22/89, effective 12/23/89)

WAC 468-38-100   ((Escort car requirements.)) Pilot/escort vehicle and operator requirements.   ((Escort cars are required:

(1) When vehicle, vehicles or load is over eleven feet in width, escort cars (both front and rear) are required on a two-lane highway.

(2) When vehicle, vehicles or load is over fourteen feet wide, one escort car in rear of movement is required on multiple-lane highways.

(3) When vehicle, vehicles or load is over twenty feet wide, escort cars in both front and rear of movement are required when the highway is a multiple-lane, undivided highway.

(4) When overall length of load, including vehicles, exceeds one hundred feet or when rear overhang of load measured from the last axle exceeds one-third of the total length, one escort car is required on two-lane highways. The permit may authorize a riding flagperson in lieu of an escort car.

(5) When overall length of load, including vehicles, exceeds one hundred forty feet, one rear escort car is required on multiple-lane highways.

(6) When in the opinion of the department of transportation, escort cars are necessary to protect the traveling public, for any overdimension and/or overweight move either across, upon, or along a highway.)) (1) When is a pilot/escort vehicle(s) required to accompany an extra-legal vehicle or load? A pilot/escort vehicle(s) must accompany an extra-legal load when:

(a) The vehicle(s) or load is over eleven feet wide. Two pilot/escort vehicles are required on two lane roads, one in front and one in back.

(b) The vehicle(s) or load is over fourteen feet wide. One escort vehicle is required at the rear of the movement on multilane highways.

(c) The vehicle(s) or load is over twenty feet wide. Two pilot/escort vehicles are required on multilane undivided highways, one in front and one in back.

(d) The trailer length, including load, of a tractor/trailer combination exceeds one hundred five feet, or when the rear overhang of a load measured from the center of the rear axle exceeds one-third of the trailer length plus load of a tractor/trailer combination. One pilot/escort vehicle is required at the rear of the movement on two-lane highways.

(e) The trailer length, including load, of a tractor/trailer combination exceeds one hundred twenty-five feet. One pilot/escort vehicle is required at the rear of the movement on multilane highways.

(f) The front overhang of a load measured from the center of the front steer axle exceeds twenty feet. One pilot/escort vehicle is required at the front on all two-lane highways.

(g) The rear overhang of a load measured from the center of the rear axle exceeds one-third the total length of a single unit vehicle with load. One pilot/escort vehicle is required at the rear of the movement on two-lane highways.

(h) The height of the vehicle(s) or load exceeds fourteen feet six inches. One pilot/escort vehicle with height measuring device (pole) is required at the front of the movement on all state highways and roads.

(i) The operator, using rearview mirrors, cannot see two hundred feet to the rear of the vehicle or vehicle combination.

(j) In the opinion of the department, a pilot/escort vehicle(s) is necessary to protect the traveling public. Assignments of this nature must be authorized through the department's administrator for commercial vehicle services.

(2) Can a pilot/escort vehicle be temporarily reassigned a position relative to the load during a move? When road conditions dictate that the use of the pilot/escort vehicle in another position would be more effective, the pilot/escort vehicle may be temporarily reassigned. For example: A pilot/escort vehicle is assigned to the rear of an overlength load on a two-lane highway. The load is about to enter a highway segment that has curves significant enough to cause the vehicle and/or load to encroach on the oncoming lane of traffic. The pilot/escort vehicle may be temporarily reassigned to the front to warn oncoming traffic.

(3) Can a certified flag person ever substitute for a pilot/escort vehicle? In subsection (1)(d) and (e) of this section, the special permit may authorize a riding flag person, in lieu of a pilot/escort vehicle, to provide adequate traffic control for the configuration.

(4) Must an operator of a pilot/escort vehicle be certified to operate in the state of Washington? Yes. To help assure compliance with the rules of this chapter, consistent basic operating procedures are needed for pilot/escort vehicle operators to properly interact with the escorted vehicle and the surrounding traffic. Operators of pilot/escort vehicles, therefore, must be certified as having received department-approved base level training as a pilot/escort vehicle operator. A pilot/escort vehicle operator with a Washington state driver's license must have a valid Washington state pilot/escort vehicle operator certificate/card which must be on the operator's person while performing escort vehicle operator duties. Escort vehicle operators with a driver's license from a jurisdiction other than Washington state may acquire a Washington state escort vehicle operator certificate/card, or operate with a certification from another jurisdiction approved by the department, subject to the periodic review of the issuing jurisdiction's certification program. A current list of approved programs will be maintained by the department's commercial vehicle services office. Washington state pilot/escort vehicle operator cards must be renewed every three years.

(5) What are the pretrip procedures that must be followed by the operator of a pilot/escort vehicle?

(a) Discuss with the operator of the extra-legal vehicle the aspects of the move including, but not limited to, the vehicle configuration, the route, and the responsibilities that will be assigned or shared.

Signs reading "oversize vehicle moving ahead" on a square at least three feet on each side (in diamond configuration), with black lettering on orange background, shall be placed at points before the oversize implement enters or leaves the highway and at any entry points along the way. The signs must be removed immediately after the move has been completed.

(3) Farm implements exceeding sixteen feet wide, but not more than twenty feet wide, are required to have a special motor vehicle permit for movement on state highways. A quarterly or annual permit may be purchased by a farmer, or any person engaged in the business of selling and/or maintaining farm implements, to move within a designated area, generally three to four counties. The permit is required to be physically present at the time of movement. In addition to the safety requirements listed in subsection (2) of this section, notification of a move should be made to all Washington department of transportation maintenance areas affected by the move, to determine if the route is passable. Phone listings are provided with each permit.)) For purposes of issuing special permits and certain permit exemptions, what is considered a farm implement? A farm implement includes any device that directly affects the production of agricultural products, including fertilizer and chemical applicator apparatus (complete with auxiliary equipment). For purposes of this section, the implement must weigh less than forty-five thousand pounds, be less than twenty feet in width and not exceed fourteen feet high. If the implement is self-propelled, it must not exceed forty feet in length, or seventy feet overall length if being towed. The implement must move on pneumatic tires, or solid rubber tracks having protuberances that will not damage public highways. Implements exceeding any of these criteria must meet all appropriate requirements for special permits as referenced in other sections throughout this chapter.

(2) What dimensional criteria must be met before a special permit is required to move extra-legal farm implements? Self-propelled farm implements, including a farm tractor pulling no more than two implements, that exceeds sixteen feet in width, but less than twenty feet wide, are required to get a special permit for movement of farm implements on state highways. Note: A tow vehicle capable of carrying a load (i.e., a truck of any kind) may not tow more than one trailing implement.

(3) Will the ability to acquire a special permit to move oversize farm implements be affected if the implement(s) is carried on another vehicle? The ability to use a special permit for farm implements as defined in subsection (1) of this section will not be affected unless one of the following circumstances occurs:

(a) The authorized users of the permit outlined in subsection (4) of this section use a commercial for-hire service to move the implement(s); or

(b) The loaded farm implement creates a combined height that exceeds fourteen feet; or

(c) The loaded farm implement causes the hauling vehicle to exceed legal weight limits. The farm implement may weigh up to forty-five thousand pounds; however, the combined gross weight of implement and hauling unit may extend to the limits established in RCW 46.44.041 Maximum gross weights -- Wheelbase and axle factors.

If any of the circumstances occur, the provisions of this subsection will not apply to the movement of the farm implement. The movement will be required to comply with the appropriate requirements for special permits as referenced in chapter 46.44 RCW and in other sections throughout this chapter.

(4) How does the application process for a special permit for farm implements differ from the process outlined in WAC 468-38-050? Due to the size of the implement and the potential for use in multiple jurisdictions, the written application must be submitted to the department's Olympia office for approval. Permits can be requested for a three-month period up to one year. Once approved, the special permit may be generated from the Olympia office by facsimile or a letter of authorization will be sent allowing the applicant to acquire a permit at the nearest permit sales location. If the movement of the farm implement(s) is confined to a single department maintenance area, the applicant may make direct written application to that maintenance area office in lieu of the Olympia office.

(5) Who is authorized to acquire this specific special permit? The acquisition and use of a special permit to move farm implements is restricted to a farmer, or anyone engaged in the business of selling, repairing and/or maintaining farm implements.

(6) Does the permit restrict the movement to a specific area? The special permit to move farm implements is generally restricted to six contiguous counties or less. With proper justification the area can be expanded.

(7) Are notifications of movement required? Movements of vehicles in excess of sixteen feet wide must be communicated to all department maintenance areas affected at least eight hours in advance. The communication is for the purpose of ensuring there will not be any planned activity that would restrict the move. Locations of maintenance area offices and phone listings are provided with each letter authorizing the purchase of the special permit.

(8) What safety precautions must be taken when moving extra-legal farm implements? The movement of extra-legal farm implements must comply with the following safety requirements:

(a) Oversize load signs: If the farm implement exceeds ten feet wide, it must display an "OVERSIZE LOAD" sign(s) visible to both oncoming traffic and overtaking traffic. Signs must comply with the requirements of WAC 468-38-155(7). If the implement is both preceded and followed by pilot/escort vehicles, a sign is not required on the implement itself.

(b) Curfew/commuter hours: Movement of a farm implement in excess of ten feet wide must comply with any published curfew or commuter hour restrictions.

(c) Red flags: If the farm implement is moving during daylight hours, and exceeds ten feet wide, the vehicle configuration must display clean, bright red flags. The flags must measure at least twelve inches square and be able to wave freely. The flags are to be positioned at all four corners, or extremities, of the overwidth implement and at the extreme ends of all protrusions, projections or overhangs. If a transported implement overhangs the rear of transporting vehicle or vehicle combination by more than four feet, one flag is required at the extreme rear. If the width of the rear overhang/protrusion exceeds two feet, there must be two flags positioned at the rear to indicate the maximum width of the overhang/protrusion.

(d) Warning lights and slow moving emblem: Lamps and other lighting must be in compliance with RCW 46.37.160. In addition to the lighting requirements, RCW 46.37.160 also requires the use of a "slow moving emblem" for moves traveling at twenty-five miles per hour or less.

(e) Convoys: Convoys, the simultaneous movement of two or more individually transported implements, are authorized when the following criteria are met:

(i) A minimum of five hundred feet is maintained between vehicles to allow the traveling public to pass safely;

(ii) If five or more vehicles are lined up behind any one of the implements, the operator must pull off the road at the nearest point wide enough to allow the vehicles to pass safely; and

(iii) The convoy is preceded and followed with properly equipped pilot/escort vehicles.

(9) Are there any unique requirements or exemptions regarding the use of pilot/escort vehicles with farm implements? Pilot/escort vehicles must comply with the requirements of WAC 468-38-100, except for the following specific exemptions related only to special permits for moving farm implements:

(a) A farmer, farm implement dealer, or agri-chemical dealer (including employees of each) is exempt from WAC 468-38-100(4) regarding operator certification, WAC 468-38-100 (8)(a) and (b) regarding escort vehicle physical description, WAC 468-38-100 (10)(f) regarding use of height measuring device, and WAC 468-38-100(11) regarding passengers, when moving a farm implement off the interstate and on the following interstate segments:

Exceptions to these limitations may be proposed to the district administrator, or designee, for review and final determination, assuming compliance with the remaining conditions contained herein.

(2) The maximum distance a structure, exceeding the above dimensions, may move is five miles. Additional contiguous five-mile permits shall not be issued to exceed the five-mile limitation. An exemption may be granted by the district administrator, or designee, if the permittee can justify the move as in the public interest or as the avoidance of extreme hardship. Justification will generally require independent documented evidence supporting the basis for the move, to include, but not be limited to: Cost, equity, and sales data; historic significance; public benefit; or national defense.

(3) An application for move must be completed and submitted to the district administrator, or designee, at least ten working days before the scheduled move. The application (form number DOT 720-028) must show, at a minimum: The owner, the mover, proposed route - complete with traffic control plan, a physical description of the structure, arrangements for moving overhead obstacles, the number and configuration of hauling vehicles (towing unit, dollies, etc.), and any additional requirements outlined in this section.

(4) When deemed necessary a department of transportation employee shall make a visual inspection of the structure, hauling vehicles, and proposed route. This inspection shall, at a minimum, verify dimensions (to include eaves, porches, and other appurtenances that could not be removed without affecting structural integrity), check for appropriate strapping for brick/masonry, verify that all overhead obstacles have been identified, insure that dollies are not equipped with hard rubber or solid cushion rubber tires, verify the tow vehicles (a back-up vehicle may be required on site for the move) have a valid certificate of inspection from the Washington state patrol, and determine if state forces will be required for the move (state force work will be estimated and paid by the permittee in advance, with actual costs being determined and a billing/refund occurring of any adjustment at the end of the move). Necessary equipment to make the inspection, such as a ladder, will be provided on site by the owner or mover.

(5) The maximum speed shall not exceed twenty-five miles per hour. Time allotted for traffic delays shall be at district discretion, but shall not exceed five minutes. Reasonable accessibility for emergency vehicles to navigate around the load shall be maintained.

(6) Special escort car requirements may be imposed to assure the movement will be made under the safest possible conditions. Documentation must be provided that shows the escort vehicle operators and accompanying flagpersons have been certified by the department of labor and industries. Hard hats and vests will be required for all flagpersons directing/controlling traffic during the movement.

(7) The applicant shall notify the Washington state patrol forty-eight hours in advance of the scheduled move, providing the Washington state patrol with time and route. The district may require the applicant to have the Washington state patrol assist with traffic control, the cost to be borne by the permittee.

(8) Routes involving the movement of overhead traffic signals, wires, and/or mast arms must be approved by the district traffic engineer.

AMENDATORY SECTION(Amending WSR 95-24-076, filed 12/4/95, effective 1/4/96)

WAC 468-38-405   Superloads ((movement criteria)).   (1) ((Superloads are defined as loads exceeding two hundred thousand pounds gross weight, and/or loads whose dimensions exceed either sixteen feet in height or sixteen feet in width.

(2) Pursuant to RCW 46.44.091(6), loads exceeding the two hundred thousand pounds gross weight must submit a written application for special permit at least thirty days in advance of the proposed move.

(3) Application for special permit to move a load in excess of sixteen feet high or sixteen feet wide must be submitted in writing at least seven calendar days before the proposed move.

(4) As part of the superload application the applicant must submit the following information:

(a) Documentation that the move is in the public interest and that alternative methods of transport are not feasible.

(b) A schematic or photograph of the item with an explanation of why it cannot be transported in smaller pieces must be provided.

(c) A schematic of the transporting laden vehicle(s), including axle loadings, axle spacings (measured from hub centers), tire sizes, number of tires per axle, and combination vehicle/load height, length and width.

(d) A traffic control plan depicting the route and specific procedures that will be followed to control traffic flow along the route, including estimated traffic delays, lane restriction, use of escort vehicles and flag persons, movement of overhead obstacles, railroad schedules for crossings, and provisions for emergency vehicles to navigate around the load.

(5) If the department determines that the move is necessary, an analysis of structures and pavements will be performed. If, due to the size of the load, the analysis will require a significant expenditure of time by department staff, the applicant may be required to share in those costs.

(6) If structures or pavements are found to be inadequate, and an alternative route cannot be found, the application for special permit will be denied. The load will have to be reconfigured in such a manner as to resolve the inadequacies of the original application.)) What are the criteria that defines a superload in Washington state? A superload is any nondivisible load that exceeds two hundred thousand pounds and/or exceeds outside dimensions of sixteen feet in height, or sixteen feet in width or have a trailing unit(s) plus load in excess of one hundred twenty-five feet in length.

(2) Will a special permit applicant need to provide additional lead-time for processing the superload application? Pursuant to RCW 46.44.091(5), applicants attempting to move loads in excess of two hundred thousand pounds must submit their application at least thirty calendar days in advance of the proposed move. Applicants that are attempting to move a load that does not meet the weight criteria for a superload but does meet the dimensional criteria must submit their application at least seven calendar days before the proposed move. All applications must be submitted in written form. Electronic submissions are considered as written format. These lead-times are necessary to allow the department sufficient time to perform an analysis of pavements and structures that would be affected by the proposed move.

(3) Are there requirements for additional information to accompany the standard application form? All, or selections from, the following information may be required as part of the standard application:

(a) Documentation that the move is in the public interest and that an alternative method of transport is not feasible.

(b) A schematic or photograph of the item to be moved, including an explanation of why it cannot be moved in smaller pieces.

(c) A schematic of the loaded vehicle(s), including axle loadings, axle spacings (measured from the center of each axle), tire sizes, number of tires per axle, and the proposed height, length and width of the configuration.

(d) A traffic control plan depicting the route and specific procedures to be followed to provide safe movement along the route, including:

(i) Identified locations where anticipated traffic delays will occur and where the delays can be allowed to clear;

(ii) Description of any lane restrictions;

(iii) How pilot/escort vehicles and flag persons will be used;

(iv) Arrangements for the movement of overhead obstacles;

(v) Identification of railroad crossings and contact information, including a pretrip analysis of each crossing to assure vehicle(s) will clear the grade;

(vi) Provisions for emergency vehicles to navigate around the configuration; and

(vii) Contact information for on-call services in case of mechanical failure (i.e., need to replace tow vehicle during movement).

(4) Will the applicant bear any of the cost of analysis performed by the department? If, due to the size of the configuration, the analysis will require a significant expenditure of department resources, the applicant may be required to share in those costs. Estimates would be provided to the applicant prior to beginning the analysis, allowing the applicant to make the decision on whether or not to proceed.

(5) If either pavements or structures are found to be inadequate, what options does the applicant have? When either the pavement or a structure on the proposed route is found to be inadequate, the permit application will be denied. The applicant must find an alternative acceptable route, or reconfigure the transported item on a vehicle(s) that can conform to the limitations of the proposed route.

(6) Will a superload require the use of pilot/escort vehicles beyond the requirements established in WAC 468-38-100(1)? Additional pilot/escort vehicles, and/or law enforcement vehicles, may be required as a result of the dimension of the load relative to the route and the time of day the move will be made. As indicated in WAC 468-38-100 (1)(j), assignments of this nature must be authorized through the department's administrator for commercial vehicle services. The motor carrier when planning a superload move must take into consideration the potential for additional vehicles.

AMENDATORY SECTION(Amending Order 31, Resolution No. 156, filed 8/20/82)

WAC 468-38-420   Bridge restrictions.   ((The department shall from time to time evaluate the capacity of all bridges on the state highway system to carry loads. Bridges that cannot safely carry vehicles moving without a permit shall be posted. Vehicles exceeding the posted load limit shall not cross the bridge.

Vehicles carrying overloads authorized by special motor vehicle permit may not cross restricted bridges noted on the permit.)) (1) What is the difference between posted bridges and restricted bridges, and how do they apply to legal and extra-legal vehicles?

(a) Posted bridges: The department performs periodic inspections and evaluates the capacity to carry loads on all bridges on state highways. Bridges that are identified as unable to safely carry vehicles with legal weight, per RCW 46.44.041, must be posted (signed) with the maximum weight limits. Applications for extra-legal weight moves that exceed a posted bridge limit on the requested route will be returned to the applicant by the department. The applicant may change the vehicle configuration to comply with the posted limit or change the proposed route. Vehicles that exceed the posted load limit must not cross the bridge.

(b) Restricted bridges: Most bridges on state highways can safely carry legal vehicle weights, per RCW 46.44.041; however, some bridges may not be capable of carrying extra-legal weights, provided for in RCW 46.44.091. The department, based on periodic inspections and evaluations, may determine that a vehicle cannot safely cross a bridge at extra-legal weights. As a result, the department must restrict axle weights on the identified bridges. These restrictions are not posted on the bridge, but are disclosed to the special permit applicant during the permitting process. Applications that exceed a bridge restriction on the requested route are returned to the applicant by the department. The applicant may change the vehicle configuration to comply with the restriction or change the proposed route. Vehicles with extra-legal weight authorized by special permit must comply with any bridge restriction noted on the permit. A violation of any restriction will cause the special permit to become null and void.

(2) Is there a published list of posted and restricted bridges? Yes. The department publishes and maintains both lists on the department's website. A hard copy is also available upon request, but has limited value due to the frequency of changes.
