Which of the following best describes Gross Weight?

Gross Weight refers to the total weight of a vehicle when it is fully loaded, meaning it includes not only the weight of the vehicle itself but also the weight of any cargo and the driver. This is important for safety regulations and compliance, as understanding the gross weight helps in ensuring that a vehicle is not overloaded, which can affect performance and safety on the road.

In contrast, the other options describe different weight classifications. The weight of a vehicle with its trailer attached pertains to a different metric, while the weight of a vehicle alone does not take into account the additional load that is routinely carried. The maximum allowable weight for a vehicle on public roads refers to regulations governing weight limits, which is also separate from the gross weight concept. Understanding these distinctions is crucial for vehicle safety inspections and compliance with state regulations.
