V27: Gross Vehicle Weight / Gross Combination Weight
The Gross Vehicle Weight Rating (GVWR) is the amount recommended by the manufacturer as the upper limit to the operational weight for a motor vehicle and any cargo (human or other) to be carried.
The Gross Combination Weight Rating (GCWR) is the sum of all GVWRs for each unit in a combination-unit motor vehicle. Thus, for single-unit trucks there is no difference between the GVWR and the GCWR. For combination trucks (truck tractors pulling a single semi-trailer, truck tractors pulling double or triple trailers, trucks pulling trailers, and trucks pulling other motor vehicles) the GCWR is the total of the GVWRs of all units in the combination. (See Example).
(From a State Police Instruction Manual): GVWR and GCWR are manufacturer designated weight ratings, not the loaded weights from the bill of lading or the scaled weight of the vehicle.
(See ANSI'D16, 7th Edition for additional definitions)
Gross Vehicle Weight Rating (GVWR) of the power unit of a combination-unit truck or a single-unit straight truck:
Gross Combination Weight Rating (GCWR) of the power unit and towed units of a combination-unit truck:
- Not Applicable
- 10,000 lbs. or less
- 10,001 - 26,000 lbs.
- More than 26,000 lbs.
(**Required by the Federal Motor Carrier Safety Administration CFR 350.201.) The Federal Motor Carrier Safety Administration (FMCSA) imposes certain regulations on all single or combination-unit trucks that have a Gross Combination Weight Rating (GCWR) of more than 10,000 lbs. Additional regulations are imposed on all motor vehicles with GCWRs of more than 26,000 lbs. This data element is collected at the scene because FMCSA requires reporting within 90 days.
