About the project
Truck size and weight (TS&W) laws affect all Minnesotans. They influence the price of the goods we buy and the condition of the roads we drive on. The Minnesota Department of Transportation has reviewed truck size and weight laws. As part of this project, meetings with public and private stakeholders were held around the state to talk about existing state laws regarding allowable commercial truck weight limits, lengths and widths. The results of this study may be used to recommend changes, including restrictions and conditions, and introduce legislation during future legislative sessions.
Laws regarding allowable weight limits, lengths, and widths of commercial motor vehicles are designed to ensure safe vehicle operation on Minnesota’s roadways and to preserve the state’s investment in highway and bridge infrastructure. Federal laws govern limits on the Interstates and other selected state highways. TS&W laws affect the cost of transportation for Minnesota’s freight shippers and carriers. At the same time, studies have documented the impacts of heavily loaded and overloaded trucks on pavement surfaces and bridge structures.
In recent years, the Legislature has approved many exceptions and special provisions to state laws governing TS&W on state and local roads. In light of changing patterns of economic growth and logistics, continued increases in truck traffic, and numerous requests for changes to laws, it has become apparent that a comprehensive review of Minnesota’s state TS&W laws is needed.
