Gross combination weight (GCW) is the total weight of which components?

• A. The total weight of the cargo only.
• B. The weight of the power unit alone.
• C. The total weight of the trailer and cargo.
• D. The total weight of the power unit and the cargo.

Answer: (D)

Gross combination weight is the total weight of the power unit and the cargo. This matters because it represents the overall load of the towing setup that the vehicle must move, brake for, and be rated to handle. It combines the tractor’s own weight with the payload it’s hauling, giving the complete picture of how heavy the combination is. The other options miss part of the reality: counting only the cargo ignores the tractor’s own weight, counting the power unit alone ignores the load, and counting the trailer plus cargo omits the weight of the power unit itself.
