The Federal Bridge Gross Weight Formula is a mathematical formula used in the United Statesto determine the appropriate gross weight for a long distance moving vehicle, based on the axle number and spacing. Enforced bythe Department of Transportation upon long-haul truck drivers, it is used as a means of preventing heavy vehicles from damaging roads and bridges.This is especially in particular to the total weight of a loaded truck, whetherbeing usedfor commercial moving services or for long distance moving services in general.
According to the Federal Bridge Gross Weight Formula, the total weight of a loaded truck (tractor and trailer, 5-axle rig) cannot exceed 80,000 lbs in the United States.Under ordinary circumstances, long-haul equipment trucks will weight about 15,000 kg (33,069 lbs). This leaves about 20,000 kg (44,092 lbs) of freight capacity.Likewise, a loadis limitedto the space available in the trailer,normallywith dimensions of 48 ft (14.63 m) or 53 ft (16.15 m) long, 2.6 m (102.4 in) wide, 2.7 m (8 ft 10.3 in) high and 13 ft 6 in or 4.11 m high.
