Wyoming Tractor Trailer Weight and Dimension Limits



Wyoming has very simple regulations surrounding weights and measures. For instance, to carry up to 117,000 lbs only bridge compliance is required. Long trailers of 60 feet are allowed in Wyoming, and straight trucks can also be this length. However, turnpike doubles are not used as the total cargo carrying length is 81’, limiting the effective use of LCVs to Rocky Mountain Doubles.

Wisconsin Tractor Trailer Weight and Dimension Limits



Wisconsin has slightly different axle weights permitted on tandem axles, with slightly more permissive weights allowed. Twin trailers are not allowed off of designated highways, and a towbar length of 12’ is specified. There is a kingpin to center of tandems distance of 43’ specified in Wisconsin, which is longer than most other states that do have a length specified. Non-designated highways have weight reductions of 60%. True to the stereotype, Wisconsin has lots of exemptions for dairy haulers.

West Virginia Tractor Trailer Weight and Dimension Limits



West Virginia follows regular interstate laws on the interstate, and also restrict the operations of twin trailers off the interstate system. There is a tolerance of 10% of gross weight on state roads, with no specifications for axle weights other than each axle cannot be greater than 20,000 lbs. Also, the kingpin specification is untypical in West Virginia. For trailers between 48’ and 53’, there must be a rear tractor to first trailer axle distance of 37’, which is about the same as a 41’ distance for most configurations. County Roads have maximum weights of 65,000 lbs plus tolerances.

Washington State 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.

Virginia Tractor Trailer Weight and Dimension Limits



Virginia has regulations that are in line with federal regulations. Virginia requires a Kingpin to Rear Axle group measurement, as well as restricting twin trailer combinations on non-designated highways. There is one notable exception, and that is the availability of ‘overload permits’ which allow a 5% increase in axle and gross weights on state roads.
