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

• A. The total weight of the cargo only.
• B. The total weight of the trailer and cargo.
• C. The weight of the power unit alone.
• 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 being carried. In a tractor-trailer setup, this means adding the weight of the tractor to everything it is pulling—the trailer and its load. This total on the road determines braking, handling, and overall safe operation, so the combined weight must include both the power unit and the cargo (the towed portion). The other ideas miss part of the picture: cargo only omits the tractor, the trailer and its load would miss the tractor’s weight, and the power unit alone leaves out what is being hauled.
