Compilation of Existing State Truck Size and Weight Limit Laws: Report to Congress

This Report to Congress on the Compilation of Existing State Size and Weight Limit Laws fulfills the requirements of Section 32802 of the Moving Ahead for Progress in the 21st Century Act (MAP-21). Section 32802 requires the Secretary of Transportation to develop a compilation of State laws that were in effect on or before the enactment of MAP-21 (October 1, 2012), and enabled vehicles to operate on segments of the National Highway System (NHS) in excess of current Federal truck size and weight limits. In accordance with Section 32802, the compilation of State laws was completed in consultation with the States through a partnership with the Association of State Highway and Transportation Officials (AASHTO).To complete the required compilation of State laws and regulations, a list of statutory limitations and exemptions for each State was developed using statutes and other online resources from State agencies. The information for each State was compiled into a State Truck Size and Weight Profile. Because Federal truck length limits are permissive [e.g., Federal laws prescribe the minimum dimensions States must allow on the National Network (NN)] and because there are no Federal limits for vehicle height, the information in the compilation focuses primarily on vehicle weight and State laws or regulations that allow trucks to travel on non-Interstate elements of the NHS at weights greater than allowed by Federal Interstate limits. On the NN, no State may impose a width limitation of more or less than 102 inches. At the time this report was compiled, there were no instances discovered in which State laws enable vehicles to operate in excess of this standard, other than through the issuance of oversize permits. This report is structured with two main components. The first component is a section providing background on U.S. truck size and weight limits and discusses exemptions to Federal truck size and weight limits. The second component comprises two appendices. Appendix A fulfills the requirements for the Report to Congress pursuant to MAP-21 Section 32802, containing an opening discussion of common State exemptions to Federal size and weight limits standards and a by-State Compilation of Truck Size and Weight Laws (State profiles). Appendix B outlines State exceptions to Federal truck weight limits.
