A gross vehicle weight rating (GVWR) is the maximum allowable total weight of a roa vehicle or trailer that is loaded, including the weight of the vehicle itself plus fuel, passengers, cargo, and trailer tongue weight. In the United States, two important GVWR limitations are 6,000 pounds (2,721 kg) and 8,500 pounds (3,856 kg). Vehicles over 6,000 pounds are restricted from many city roadways (though there is some dispute about whether this restriction is for actual curb weight or GVWR), and vehicles over 8,500 pounds do not have to display EPA estimated fuel mileage or a Monroney sticker nor are they subject to state emissions testing.
