Gross Combination Weight Rating (GCWR); Definition

Direct final rule; request for comments.

The Federal Motor Carrier Safety Administration (FMCSA) amends the definition of "gross combination weight rating" (GCWR) in our regulations. The definition currently prescribes how the GCWR is calculated if the vehicle manufacturer does not include the information on the vehicle certification label required by the National Highway Traffic Safety Administration (NHTSA).

Therefore, FMCSA amends this definition to state that the GCWR is the value specified by the commercial motor vehicle manufacturer.
