What is the term for the amount of weight that a truck carries, including driver, passengers, cargo, and tongue or king pin weight?

The correct term for the total weight that a truck carries, which encompasses the driver, passengers, cargo, as well as tongue or king pin weight, is known as "Gross Vehicle Weight." This measurement reflects the cumulative weight of the entire vehicle and its contents when fully loaded, providing an essential metric for vehicle classifications and regulations concerning weight limits. Understanding this concept is vital for ensuring compliance with safety standards and optimizing performance, as operating a vehicle above its rated weight can lead to increased wear and tear, reduced fuel efficiency, and potential safety hazards. The distinction between "Gross Vehicle Weight" and terms like "Payload," which typically refers to the maximum weight a vehicle can carry without including its own weight, is important in discussions of vehicle capacity and operational limits.
