Federal Motor Vehicle Safety Standard Label
Tractors with or without fifth wheels purchased in the U.S. are marked as certified by means of a FMVSS label. An example label is shown in Fig. .
Fig. 1, FMVSS Certification Label
Fig. 2, Incomplete FMVSS Certification Label
The tire and rim portion of the FMVSS certification label certifies suitable tire and rim combinations that can be installed on the vehicle, for the given gross axle weight rating. Tires and rims installed on the vehicle at the time of manufacture may have a higher load capacity than that certified by the tire and rim label.
If the tires and rims currently on the vehicle have a lower load capacity than that shown on the tire and rim label, then the tires and rims determine the load limitations on each of the axles.
The FMVSS labels are attached to the driver-side door B-pillar, as shown in Fig. .

Trucks built without a cargo body that are intended for service in the U.S. have an incomplete FMVSS certification label. See Fig. for a label example. This label will be attached to the incomplete vehicle document included with the vehicle.
After completion of the vehicle, a complete certification label must be attached by the final-stage manufacturer to certify that the vehicle conforms to all applicable FMVSS regulations in effect on the date of completion.
