What is the term for the total weight of the powered unit, the trailer, and the cargo?

The total weight of the powered unit, the trailer, and the cargo is referred to as gross combination weight. This term is important because it encompasses the combined mass of all components involved in a combination vehicle, including the tractor (powered unit), any trailers attached, and the cargo being carried. Understanding this concept is crucial for ensuring compliance with weight regulations, as trucking companies must adhere to limits that are set for safe operation on public roadways.

In contrast, net vehicle weight specifically pertains to the weight of the vehicle itself without any cargo or trailer attached. Payload capacity refers to the maximum amount of weight that can be safely transported in a vehicle, while operating weight typically includes the vehicle's weight plus any additional load (but not necessarily the entire combination of powered unit and trailer). Therefore, gross combination weight is the most accurate term for the total weight in question.
