Gross Combination Weight Rating

Source of Definition: 49 CFR 383; 49 CFR 390

Source of Data: Vehicle Manufacturer

Synonyms: GCWR

A value specified by the manufacturer as the loaded weight of a combination vehicle. That is the sum of the GVWR values specified by the manufacturer for a loaded truck tractor and any loaded trailers it will tow.

This element holds the numeric quantity, using the default units of measure of the jurisdiction. Given a source document showing "14,500 LB/6,577 KG", this element would hold a value of 14500 in a U.S. jurisdiction.

49 CFR 383.5 and 49 CFR 390.5 specify: Gross combination weight rating (GCWR), is the greater of:

1. A value specified by the manufacturer of the power unit, if such value is displayed on the Federal Motor Vehicle Safety Standard (FMVSS) certification label required by the National Highway Traffic Safety Administration, or
2. The sum of the gross vehicle weight ratings (GVWRs) or the gross vehicle weights (GVWs) of the power unit and the towed unit(s), or any combination thereof, that produces the highest value. Exception: The GCWR of the power unit will not be used to define a commercial motor vehicle when the power unit is not towing another vehicle.
