The third formula is 1,600 times (the wheelbase in feet plus 40) when wheelbase is more than 30 feet. This table limits maximum weights to no more than 21,500 pounds per axle and 43,000 pounds per tandem axle. Permit Weight Table 4, revised January 2023, is by reference made part of Division 82 rules, and is available from the CCD Over-Dimension Permit Unit.
