Commercial Vehicle Guide
The Washington State Commercial Vehicle Guide is intended for the professional commercial vehicle operator and others who are concerned about safe truck operations. It has been compiled by Commercial Vehicle Services within the Washington State Department of Transportation (WSDOT) in cooperation with the Commercial Vehicle Enforcement Bureau of the Washington State Patrol (WSP/CVD), Washington State Department of Licensing (WSDOL) Driver and Vehicle Services Divisions, the Washington Utilities and Transportation Commission (WUTC), and the U.S. Department of Transportation, Federal Motor Carrier Safety Administration (FMCSA), in an effort to provide a starting point for information for commercial vehicle operators driving within the State of Washington.
