The Federal Highway Administration has released its Compilation of Existing State Truck Size and Weight Limit Laws. This publication was requested by Congress in 2012 in the MAP-21 highway bill. It is a compendium of state size and weight regulations, in effect on October 1, 2012, that allow vehicles operating on the National Highway System to exceed federal size and weight limits. In addition to limits for trucks in regular operation, the report includes exemptions for specific commodities or types of vehicle. Because federal length law is permissive, the report focuses almost exclusively on weight limits.
