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). The Agency has determined the definition should not include what is essentially guidance that is difficult for the motor carrier and enforcement communities to use. Therefore, FMCSA amends this definition to state that the GCWR is the value specified by the commercial motor vehicle manufacturer.
