What does Gross Combination Weight Rating (GCWR) indicate?

  1. The total weight of a loaded trailer

  2. The maximum weight of the trailer alone

  3. The maximum weight specified by the manufacturer for a vehicle plus its load

  4. The minimum weight a trailer must carry

The correct answer is: The maximum weight specified by the manufacturer for a vehicle plus its load

The correct choice indicates the maximum weight specified by the manufacturer for a vehicle, including its load. This measure is crucial for ensuring safe operation of a combination vehicle, which typically involves a truck and a trailer. GCWR is important because exceeding this limit can lead to dangerous driving conditions, including difficulty in braking, reduced stability, and increased wear on vehicle components. Understanding GCWR allows drivers to make informed decisions about towing and loading, ensuring compliance with safety regulations. The other options do not fully encompass the meaning of GCWR, as they either focus on specific weights of the trailer alone or do not consider the vehicle’s weight and capability as a whole.
