The conventional view is that U.S. federal limits govern trucks operating across the Canadian-U.S. border. The identification of 118 roads crossing the border and a description of the regulations in neighboring provinces and states governing traffic on them are provided. Surveys at 25 crossings that carry 87% of cross-border truck traffic have identified truck configurations in different regions. The standard five-axle tractor-semitrailer, at a gross vehicle weight of up to 36,287 kg (80,000 lb), is the principal truck used between the two countries, but mainly for low-density freight or long hauls. Almost 22% of trucks crossing the border are configured to carry payloads heavier than possible with this truck. Most have at least six axles, and many make use of liftable axles. Local cross-border trucking operations are making significant use of trucks larger and/or heavier than those allowed under U.S. federal regulations and under provincial and state regulations, grandfather rights, or permits. |
