Washington Tractor Trailer Weight and Dimension Limits

Washington has truck regulations that keep it competitive with neighboring states and British Columbia. Trucks can gross up to 105,500 lbs and have longer double trailer lengths available under a permit. Because of this, B-Train units for heavier loads travel in Washington State. Another unusual dimension that is specified in Washington State is that a load overhanging the rear of the vehicle is not measured from the end of the vehicle, but from the center of the rearmost axle.
