Background:  The federal bridge formula is a nationally recognized weight table that states are required to use when determining the maximum gross weight a vehicle may legally carry on a highway.  The formula is based on the relationship between gross weight, the number of axles used and the spacing between axles.  A recent review by the Federal Highway Administration concluded that Washington's statutory weight table, which is based on the federal bridge formula, contained five inconsistencies.

 

The overweight fee schedule is the statutory fee schedule, designed to recover costs associated with vehicles carrying nondivisible loads that exceed legal vehicle weight limitations.  The schedule reflects the geometric increase in pavement damage as overlegal weights increase.  Legal limitations are 105,500 pounds gross vehicle weight and/or 20,000 pounds on a single axle, 34,000 pounds on a tandem axle.  The schedule is a graduated fee per mile, based on excess weight "over total registered gross weight."  The schedule is capped at 80,000 pounds "over total registered gross weight."  A recent review by the Department of Transportation indicates two problems with this verbiage: 

 

(1)  "Over total registered gross weight."  It is possible for a vehicle to be within the limits of its legal registered gross weight but, because of the type of nondivisible load it is carrying, certain axles may have exceeded legal axle limits.

 

To ensure that both registered gross weight and axle weight limitations are considered when determining when to apply the overweight fee schedule, the term "weight over total registered gross weight" needs to be changed to "excess weight over legal capacity."

 

(2)  80,000 pound cap.  Because the fee schedule is capped, loads exceeding the fee schedule are not paying in proportion to the added cost to the highway.  The fee schedule falsely assumes that, at 80,000 pounds over total registered gross weight, the cost no longer increases.  For example, a vehicle registered at 105,500 pounds carrying an additional 80,000 pounds (total of 185,500 pounds) pays the same fee as a vehicle registered at 105,500 pounds carrying an additional 150,000 pounds (total of 255,500 pounds).  As of 1990, this fee schedule would have handled almost anything that moved on the highway without reaching the capped upper limit.  Since then, however, there has been a growth in specialized moves exceeding the cap.  A few of these moves have been in the 300,000 to 400,000 pound gross weight range (i.e., hydroelectric plant transformers).  If cost recovery is to be kept in proportion to cost incurred, the cap would have to be removed.

 

Summary:  Washington state's statutory weight table is brought into compliance with the federal bridge formula.

 

The overweight fee schedule applies to "excess weight over legal capacity" to ensure that both the registered gross weight and axle weight limitations are considered when applying the schedule.

 

The 80,000 pound cap on the state's overweight fee schedule for nondivisible loads is removed.  The graduated schedule is revised to recover cost per mile for vehicles exceeding either gross weight or axle weight legal limits.  The schedule begins at 7 cents per mile for 0 to 9,999 pounds over legal capacity and graduates geometrically to $4.25 per mile for 100,000 pounds over legal capacity.  The schedule continues with a fixed increment of 50 cents for each 5,000 pounds in excess of the 100,000 pound fee.
