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").

Bridge formula check with West Virginia limits

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.

Axle spacings

Center of one axle to the center of the next, in feet. Axle 1 is the steer axle. 4 ft 6 in = 4.5.

Axle weights (optional)

From your scale ticket. Leave all blank to see the limits only.

Your result

Enter your axle spacings and tap "Check bridge formula". A 5-axle tractor-trailer is filled in.
