What is the total weight of a powered unit, the trailer, and the cargo called?

A. Total payload
B. Combined weight
C. Gross combination weight
D. Net weight

The correct answer is: C. Gross combination weight

The term that refers to the total weight of a powered unit, the trailer, and the cargo is "Gross Combination Weight." This definition encompasses all components involved in the weight calculation for vehicles that are towing trailers, which is critical for ensuring compliance with weight regulations and safety. Understanding gross combination weight is essential for operators of commercial vehicles to prevent overloading, maintain control, and ensure safe operation. It is vital that drivers know this total weight to adhere to state and federal transportation laws, as exceeding weight limits can lead to penalties and increased risk of accidents. The other terms don’t accurately capture the entirety of the weight of the powered unit and trailer combination. "Total payload" focuses specifically on the weight of the cargo without including the vehicle itself or the trailer. "Combined weight" might seem similar, but it lacks the specificity of referring to the regulatory definition. "Net weight" refers to the weight of the cargo alone, excluding the weight of the vehicle and trailer, making it unsuitable for this context.
