Trucks are classified based on their “Gross Vehicle Weight Rating” (GVWR).
This is a rating system used by manufacturers and governments that limit the maximum amount of weight a truck can haul including, the truck, fuel, load on the truck and the passengers. Trucks are classified from Class 1 small pickups 
with a GVWR of 6,000 lbs. or less to class 8 with a GVWR of 33,001 lbs. or greater and everything in between.
While the primary function of the passenger car is to haul people the primary application of the truck is to haul things and deliver them safely. As the class of the truck increases the size and weight of the parts that go into the vehicle increase.
