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.
