Do I need GVW on my truck door? The gross weight decal explained

Short answerFederal rules do not require the gross vehicle weight on the door. Only your name and USDOT number are required by 49 CFR 390.21. Some states require intrastate carriers to display the GVW or GVWR, usually on the door below the USDOT number, and some registration systems tie your fee to the weight you declare and expect it to be shown. If your state asks for it, it is a two inch line that reads GVW followed by the number.

Federal: not required

The federal marking rule asks for two things on the power unit: the carrier's name and the USDOT number. Nothing about weight. If you only run under federal interstate authority, you can skip the GVW line entirely.

State: sometimes required

States that register trucks by declared gross weight sometimes require that weight to be displayed, so an inspector can compare the sticker to the scale without looking up the registration. The requirement is usually tied to intrastate operations and to the weight you declared when you registered. Rules change, so check your state's page or your registration paperwork rather than a forum post.

GVW or GVWR?

They are different numbers. GVWR is the manufacturer's rating on the door jamb sticker, the most the truck is built to weigh. GVW is the gross weight you declared at registration, which can be lower than the rating if you registered for less. States that require a door marking almost always mean the declared weight, written as GVW 26,000 or similar. When in doubt, match the number on your registration card.

How it is lettered

The GVW line goes below the USDOT number in the same style, usually 2 inches tall so it reads with the rest of the door. Our designer has a GVW line built in: add it under your numbers and it is cut on the same sheet, or order it on its own as a GVW decal if your doors are already lettered.
