That will depend on the length of the trailer, and on the wheelbase of the tractor. The maximum length for a trailer (without requiring a special permit) is 53 feet, while the legal bridge (space between the drive axles and the trailer axles) is 41 feet (except in California, where it is 40 feet). Tractors may have a wheelbase of anywhere from 100 inches to over 300 inches, although the average sleeper berth tractor for long distance haulage will have a wheelbase between 220 and 265 inches.
