About Federal Bridge Gross Weight Formula in brief

Summary Federal Bridge Gross Weight FormulaThe Federal Bridge Gross Weight Formula is part of federal weight and size regulations regarding interstate commercial traffic. The formula was enacted as law to limit the weight-to-length ratio of a commercial motor vehicle. It is necessary to prevent the concentrated weight on a truck’s axle from producing stress on bridge members. Current applications of the formula allow for up to 7 axles and 86 feet or more length between axle sets, and a maximum load of 105,500 lbs. The one exception to the formula allows a standard five-axle semi-truck configuration to weigh the maximum legal gross weight. For an overweight truck to comply with the formula, more axles must be added, the distance between axlesmust be increased, or weight must be removed. The weight andsize limits for CMVs are restricted by gross weight and by axle weight for a tandem weight of 80,000 pounds for a 34,000-pound truck. The maximum gross weight limit for a tractor-trailers or buses is 80,00 pounds for both axles, and 34,500 pounds for the tandem weight. The federal weight limits are restricted for practical and safety reasons. The limits are not in effect for intrastate commercial traffic, provided the vehicle is not on the NN.

The FMCSA enforces the length, width, and weight limits of CMVs set by the Federal Highway Administration for interstatecommercial traffic.
