Truck Route and Weight Restriction Provisions


About Truck Routes and Weight Restrictions

Local authorities are authorized by RCW 46.44.080  to prohibit the operation of motor trucks or other vehicles and to impose limits as to their weight under certain circumstances. However, local authorities  may not prohibit the use of any street designated by the State Transportation Commission as forming a part of any primary state highway or impose any restrictions or reductions in permissible weights unless the restrictions are first approved in writing by the State Department of Transportation. This statute also requires that the local authority imposing such restrictions do so by proper ordinance or resolution, and it must erect and maintain signs designating the provisions of the ordinance at each end of the public highway affected. The statute further provides that no such ordinance or resolution shall be effective until such signs are erected and maintained.
