AMENDATORY SECTION(Amending Order 127, filed 12/21/90, effective 1/21/91)

WAC 468-95-010   General.   ((The Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD), 1988 edition, and future revisions approved by the Federal Highway Administrator, except as modified by the department of transportation herein, as the national standard for all highways open to public travel, published by the U.S. Department of Transportation, Federal Highway Administration, was duly adopted by Administrative Order No. . . . . of the Secretary of Transportation dated . . . . . . .)) The June 2001 Millennium Edition of the Manual on Uniform Streets and Highway for Streets and Highways (MUTCD), published by the Federal Highway Administration and approved by the Federal Highway Administrator as the national standard for all highways open to public travel, was duly adopted by the Washington state secretary of transportation. The manual includes in part many illustrations, some of which depend on color for proper interpretation. The code reviser has deemed it inexpedient to convert these regulations and illustrations to the prescribed form and style of WAC and therefore excludes them from publication. ((Copies of the MUTCD may be obtained from the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402.)) The document is available for public inspection at the headquarters office and all ((district)) region offices of the Washington state department of transportation. Further, each city, town, and county engineering office in the state will have a copy of the MUTCD, with revisions and modifications for Washington, in its possession.

[]


NEW SECTION
WAC 468-95-190   Pavement edge lines and raised pavement markers supplementing other markings.   Pursuant to RCW 47.36.280, the Standard in MUTCD Section 3B.07, is revised as follows:

Edge lines shall be used on all interstate highways, on rural multilane divided highways, on all principal arterials and minor arterials within urbanized areas, except when curb or sidewalk exists, and may be used on other classes of roads. Jurisdictions shall conform to these requirements at such time that it undertakes to renew or install permanent markings on new or existing roadways. The lines shall be white except that on the left edge of each roadway of divided streets and highways and one-way roadway in the direction of travel, the lines shall be yellow.

These standards shall be in effect, as provided in this section, unless the legislative authority of the local governmental body finds that special circumstances exist affecting vehicle and pedestrian safety that warrant a site-specific variance.

Pursuant to RCW 47.36.280, the first paragraph under Option of MUTCD Section 3B.13 is revised to read as follows:

Raised pavement markers may also be used to supplement other markings for channelizing islands or approaches to other objects. The general use of raised pavement markers along right edge lines is strongly discouraged because they can cause steering difficulties and make bicyclists lose control of their vehicles. Raised or recessed pavement markers may be used along right edge lines on the taper in lane transition sections, on approaches to objects and within channelization at intersections. Raised or recessed pavement markers can only be used along right edge lines at other locations where an engineering study has determined the markers are essential to preserving pedestrian, bicycle, and motor vehicle safety. At the initiation of the engineering study, local bicycling organizations, the regional member of the state bicycling advisory committee, or the WSDOT bicycle and pedestrian program manager shall be notified of the study for review and comment. Positioning and spacing of the markers in such cases must be determined by engineering judgment taking into consideration their effect on bicycle, pedestrian, and motor vehicle safety. Other applications of raised or recessed pavement markers along right edge lines of arterials are considered to be nonconforming with this section. Cities and counties shall remove nonconforming raised pavement markings at the time that they prepare to resurface roadways, or earlier at their option.

These standards shall be in effect, as provided in this section, unless the legislative authority of the local governmental body finds that special circumstances exist affecting vehicle and pedestrian safety that warrant a site-specific variance.

Amend the Standard to read:

Unless specifically stated otherwise, each sign illustrated herein shall have a border of the same color as the legend, at or just inside the edge. The corners of all sign borders shall be rounded, except for STOP signs.

Amend the Guidance to read:

A dark border on a light background should be set in from the edge, while a light border on a dark background should extend to the edge of the panel. A border for 750 mm (30 in) signs with a light background should be from 13 to 19 mm (0.5 to 0.75 in) in width, and 13 mm (0.5 in) from the edge. For similar size signs with a light border, a border width of 25 mm (1 in) should be used. For other sizes, the border width should be of similar proportions, but should not exceed the stroke-width of the major lettering of the sign. On signs exceeding 1800 x 3000 mm (72 x 120 in) in size, the border should be 50 mm (2 in) wide. For signs larger than 1800 x 3000 mm (72 x 120 in), the border should be 75 mm (3 in) wide. Where practical, the corners of the sign should be rounded parallel to the border, except for STOP sign corners which are not rounded.

(2) Section 2A.19, Lateral Offset

Change the first Standard to read:

For overhead sign supports (cantilever or sign bridges), the minimum lateral offset from the edge of the shoulder (or if no shoulder exists, from the edge of the pavement) to the near edge of the supports shall be 1.8 m (6 ft).

Overhead sign supports shall have a barrier or crash cushion to shield them if they are within the clear zone.

Roadside-mounted sign supports shall be breakaway, yielding, or shielded with a longitudinal barrier or crash cushion if within the clear zone.

Notes: 1The distances are adjusted for a sign legibility distance of 50 m (175 ft) for Condition A. The distances for Condition B have been adjusted for a sign legibility distance of 75 m (250 ft), which is appropriate for an alignment warning symbol sign.
2Typical conditions are locations where the road user must use extra time to adjust speed and change lanes in heavy traffic because of a complex driving situation. Typical signs are Merge, Right Lane Ends, etc. The distances are determined by providing the driver a PIEV time of 14.0 to 14.5 seconds for vehicle maneuvers (2001 AASHTO Policy, Exhibit 3-3, Decision Sight Distance, Avoidance Maneuver E) minus the legibility distance of 50 m (175 ft) for the appropriate sign.
3Typical condition is the warning of a potential stop situation. Typical signs are Stop Ahead, Yield Ahead, Signal Ahead, and Intersection Advance Warning signs. The distances are based on the 2001 AASHTO Policy, Stopping Sight Distance, Exhibit 3-1, providing a PIEV time of 2.5 seconds, a deceleration rate of 3.4 m/second2 (11.2 ft/second2), minus the sign legibility distance of 50 m (175 ft).
4Typical conditions are locations where the road user must decrease speed to maneuver through the warned condition. Typical signs are Turn, Curve, Reverse Turn, or Reverse Curve. The distance is determined by providing a 2.5 second PIEV time, a vehicle deceleration rate of 3 m/second2 (10 ft/second2), minus the sign legibility distance of 75 m (250 ft).
5No suggested minimum distances are provided for these speeds, as the placement location is dependent on-site conditions and other signing to provide an adequate advance warning for the driver.

(5) Section 2C.27 CROSS TRAFFIC DOES NOT STOP Plaque (W4-4)

Replace the entire Section text with the following:

Option:

The CROSS TRAFFIC DOES NOT STOP (W4-4) plaque (see Figure 2C-9) may be used in combination with a STOP sign when engineering judgment indicates that drivers frequently misinterpret the intersection to be a multi-way stop condition.

Standard:

If the W4-4 plaque is used, it shall be installed below the STOP sign.

(6) Section 2C.28 Merge Signs (W4-1, W4-1a)

W4-2 Lane End sign is included in MUTCD Revision 2 Section 2C.30.

(7) Section 2C.34 Intersection Warning Signs (W2-1 through W2-6)

Amend the section to read:

Option:

A Cross Road (W2-1) symbol, Side Road (W2-2 or W2-3) symbol, T-Symbol (W2-4), or Y-Symbol (W2-5) sign (see Figure 2C-9) may be used in advance of an intersection to indicate the presence of an intersection and the possibility of turning or entering traffic. The relative importance of the intersecting roadways may be shown by different widths of lines in the symbol.

The Circular Intersection (W2-6) symbol sign accompanied by an educational word message plaque may be installed in advance of a circular intersection.

An advance street name plaque (see Section 2C.45) may be installed below an Intersection Warning sign.

Guidance:

The Intersection Warning sign should illustrate and depict the general configuration of the intersecting roadway, such as cross road, side road, T-intersection, or Y-intersection. Where the side roads are not opposite of each other, the symbol for the intersection should indicate a slight offset.

Intersection Warning signs, other than the Circular Intersection symbol (W2-6) sign should not be used on approaches controlled by STOP signs, YIELD signs, signals, or where Junction signing (see Sections 2D.13 and 2D.28) or advance route turn assembly signs (see Section 2D.29) are present. The Circular Intersection symbol (W2-6) sign should be installed on the approach to a roundabout intersection controlled by a YIELD sign.

(8) Section 2C.37 Crossing Signs (W11-1, W11-2, W11-3, W11-4, W16-7P)

Rename and replace the entire section with the following:

Section 2C.37 Nonvehicular Signs (W11-1, W11-2, W11-3, W11-4, W11-11, W11-14, W11-14a, W11-15)

Option:

Nonvehicular signs (see Figure 2C-10) may be used to alert road users in advance of locations where unexpected entries into the roadway or shared use of the roadway by pedestrians, bicyclists, golf carts, animals, horse-drawn vehicles, and other crossing activities might occur.

Support:

These conflicts might be relatively confined, or might occur randomly over a segment of roadway.

Option:

When used in advance of a crossing, Nonvehicular warning signs may be supplemented with supplemental plaques (see Section 2C.39) with the legend AHEAD, XX METERS (XX FEET), or NEXT XX KILOMETERS (NEXT XX MILES) to provide advance notice to road users of possible crossing activity.

Standard:

When used at the crossing, Nonvehicular warning signs shall be supplemented with a diagonal downward pointing arrow (W16-7) plaque (see Figure 2C-10) showing the location of the crossing.

Option:

The crossing location may be defined with crosswalk markings (see Section 3B.17). Pedestrian, Bicycle, School Advance Crossing, and School Crossing signs and their related supplemental plaques may have a fluorescent yellow-green background with a black legend and border.

Guidance:

When a fluorescent yellow-green background is used, a systematic approach featuring one background color within a zone or area should be used. Mixing standard yellow and fluorescent yellow-green backgrounds within a selected site area should be avoided.

Nonvehicular signs should be used only at locations where the crossing activity is unexpected or at locations not readily apparent.

(9) Section 2C.46 Dead End/No Outlet Plaques (W14-1P, W14-2P)

Amend the section to read:

Option:

DEAD END (W14-1P) or NO OUTLET (W14-2P) plaques (see Figure 2C-11) may be used in combination with Street Name (D3-1) signs (see Section 2D.38) to warn turning traffic that the cross street ends in the direction indicated by the arrow.

At locations where the cross street does not have a name, DEAD END or NO OUTLET plaques may be used alone in place of a street name sign.

(10) Section 3B.13 B1 Raised Pavement Markers Supplementing Other Markings

Under Guidance, amend the section to read:

B. Longitudinal Spacing

1. When supplementing solid line markings, raised pavement markers at a spacing no greater than N (see Section 3A.06) should be used, except when supplementing left edge line markings a spacing no greater than N/2 should be used. Raised markers should not supplement right edge line markings, unless they are spaced closely enough (no greater than 3 m (10 ft) apart) to approximate the appearance of a solid line.

2. When supplementing broken line markings, a spacing no greater than 3N should be used. However, when supplementing broken line markings identifying reversible lanes, a spacing no greater than N should be used.

3. When supplementing dotted line markings, a spacing appropriate for the application should be used.

4. When supplementing longitudinal line markings through at-grade intersections, one raised pavement marker for each short line segment should be used.

5. When supplementing edge line extensions through freeway interchanges, a spacing of N should be used.

(11) Section 3B.24 Markings for Roundabouts

Replace Figure 3B-27, Typical Markings for Roundabouts with Two Lanes, with the same figure in MUTCD Revision 2 available at http://mutcd.fhwa.dot.gov/pdfs/millennium/pr2/3r2.pdf. Page 69.

(12) Section 3B.25 General

Amend the section to read:

Support:

When used for guidance or regulation of traffic, colored pavements are traffic control devices. Colored pavements also are sometimes used to supplement other traffic control devices. Colored pavement located between crosswalk lines to emphasize the presence of the crosswalk is not considered to be a traffic control device.

Guidance:

Colored pavements used as traffic control devices should be used only where they contrast significantly with adjoining paved areas. Colors that degrade the contrast of white crosswalk lines, or that might be mistaken by road users as a traffic control application, should not be used for colored pavement located between crosswalk lines.

Standard:

Colored pavements shall not be used as a traffic control device, unless the device is applicable at all times. Colored pavements used as traffic control devices shall be limited to the following colors and applications:

A. Yellow shall be used only for flush or raised median islands separating traffic flows in opposite directions.

B. White shall be used for delineation on shoulders, and for flush or raised channelizing islands where traffic passes on both sides in the same direction of travel.

(13) Section 4D.18-2 Design, Illumination, and Color of Signal

Delete the entire last Guidance.

(14) Section 7A.04 Scope

Under the Standard, delete the second paragraph.
