A carrier may need an overweight/oversize permit if it exceeds a standard gross weight or size regulations set by the province. Requirements can vary from state to state. The standard gross weight is 80,000 pounds. It can also depend on axle spreads, tire sizes, and weight distribution on axles in some provinces. Standard set dimensions are 75 feet in length, 8 feet 6 inches in total width, and 13 feet 6 inches in total height.
