The second formula is 1,200 times (the wheelbase in feet plus 40) for groups of axles, vehicles or combinations of vehicles having more than 18 feet of wheelbase. Permit Weight Table 3, revised January 2023, is by reference made part of Division 82 rules, and is available from the CCD Over-Dimension Permit Unit. (27) “Permit Weight Table 4” is a table based on three wheelbase weight formulas. The first formula is 1,200 times (the wheelbase in feet plus 40) for groups of axles or combinations of vehicles having nine feet five inches or less wheelbase. The second formula is 2,200 times (the wheelbase in feet plus 20) when wheelbase is more than nine feet five inches but is not more than 30 feet. 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. (28) “Permit Weight Table 5” is a table based on the same three formulas as Permit Weight Table 4, but describes maximum weights up to 24,000 pounds per axle and 48,000 pounds per tandem axle when the combination consists of a steering axle and four or more consecutive tandem axles. Permit Weight Table 5, revised January 2023, is by reference made part of Division 82 rules, and is available from the CCD Over-Dimension Permit Unit.
