Interstate weight limits
Federal law sets the Interstate limits at 20,000 lb on a single axle, 34,000 lb on a tandem, and 80,000 lb gross, with the bridge formula on every axle group (23 CFR 658.17). States may keep higher limits they had before the federal limits took effect ("grandfather rights").

A 5-axle tractor-trailer is filled in. Change the spacings and weights to match your rig; the limits for single axles, tandems, and gross are West Virginia's Interstate limits.

- West Virginia State statute allows for several tolerances for axle weights and/or GVW.
Height, width, and length
- Width: 102 inches. States may not set a width limit of more or less than 102 inches on the National Network (23 CFR 658.15(a)). Permits can allow wider loads.
- Height: 13 ft 6 in. There is no federal height limit; each state sets its own.
- Semitrailer length: 48 ft on the National Network and designated highways; up to 53 ft where the axle spacing between the rear axle of the tractor and the front axle of the semitrailer is not more than 37 ft
- Grandfathered semitrailer length: 48 ft. The minimum semitrailer length the state must allow in a tractor-semitrailer combination on the National Network, based on lengths legal in the state on December 1, 1982. Federal law also requires at least 48 ft (23 CFR 658.13(b)(1)).
Over these limits you need a permit. West Virginia oversize/overweight permits (304-558-9547).
