Exhibit 19: Truck and Trailer
Truck Classifications
Trucks may be classified in many different ways but the most common method uses gross vehicle
weight. Manufacturers are required by law and industry standards to provide GVWR (gross
vehicle weight rating) for every vehicle, divided into eight classes. The Vehicle Inventory and
Use Survey (VIUS) provides fleet composition data for California (Exhibit 20).
