A straightforward guide to GVWR decals, GVWR lettering, and what gross vehicle weight rating signage should include on your truck
Trucks are generally required to have a manufacturer's certification label displaying their Gross Vehicle Weight Rating (GVWR), but federal regulations do not generally require GVWR lettering on the outside of the vehicle. The factory certification label, typically located on the driver's door edge or door-frame pillar, identifies the vehicle's manufacturer, date of manufacture, GVWR, front and rear Gross Axle Weight Ratings (GAWR), tire and inflation information, VIN, and applicable federal safety certification information. If this label is missing, damaged, or unreadable, contact the vehicle manufacturer or an authorized dealer about obtaining a replacement.
For commercial trucks, GVWR also plays an important role in determining whether additional vehicle identification is required. Under applicable federal regulations, certain commercial vehicles with a GVWR or gross vehicle weight of 10,001 pounds or more that operate in interstate commerce are subject to
FMCSA requirements, including displaying the motor carrier's legal or registered trade name and
USDOT number on both sides of the vehicle. Other factors can also trigger these requirements, and some states have additional commercial vehicle marking rules.
While exterior GVWR lettering is generally optional under federal regulations, some fleets choose to display it for convenient vehicle identification. These custom decals can be paired with
USDOT markings and company information, but they do not replace the manufacturer's required certification label. Understanding the difference can help truck owners determine which markings are required and which are optional.
