What is gross vehicle weight (GVW)?

Gross vehicle weight (GVW) is the total actual weight of a fully loaded vehicle — tractor, trailer, fuel, driver and cargo. The federal Interstate limit is 80,000 lb.

Gross vehicle weight (GVW) is the total actual weight of a vehicle as it sits right now — the empty vehicle plus fuel, driver, and cargo. For a loaded tractor-semitrailer it is the sum of all axle weights on the scale.

The federal limit

On the US Interstate system the maximum GVW is 80,000 lb without a permit. That is a hard cap independent of how many axles you add — extra axles raise what the Bridge Formula allows per group, but the 80,000 lb gross ceiling still governs the whole vehicle unless a state permit raises it.

GVW is the measured weight; GVWR is the manufacturer's maximum rating. They are different numbers and easy to confuse.

For a tractor and trailer rated as a combination, the equivalent term is gross combination weight (GCW).
