191. Gross Vehicle Weight Rating

Gross Vehicle Weight Rating (GVWR) is the maximum total weight at which a vehicle is designed or approved to operate when fully loaded. It includes the vehicle itself together with the driver, passengers, fuel, luggage, cargo and other equipment carried by the vehicle.

GVWR is a fixed maximum value and should not be confused with Gross Vehicle Weight (GVW), which is the vehicle's actual weight at a particular moment. The actual loaded weight of the vehicle must not exceed its permitted maximum.

What does GVWR include?

GVWR represents the permitted maximum total weight of the loaded vehicle, including the vehicle itself, driver, passengers, fuel, luggage, cargo and other equipment carried by the vehicle.

What is the difference between GVWR and GVW?

GVWR is the maximum permitted or rated weight of the vehicle, while GVW is its actual weight at a particular moment. The GVW changes as passengers or cargo are added or removed, while the GVWR remains a fixed limit.

Why is GVWR important?

GVWR determines how heavily a vehicle may be loaded and can affect driving-licence categories, vehicle classification and other legal requirements. Exceeding the permitted maximum can also adversely affect braking, handling, tyres and other vehicle components.
