Trucks classes are defined by [[gross vehicle weight rating]] (GVWR). The administrator classifies light trucks (nonpassenger automobiles) into the following classes: Small pickup trucks, standard pickup trucks, vans, minivans, and SUVs. Starting in the 2013 model year, SUVs are divided between small sport utility vehicles and standard sport utility vehicles. Pickup trucks and SUVs are separated by car line on the basis of gross vehicle weight rating (GVWR). For a product line with more than one GVWR,  the characteristic GVWR value for the product line is established by calculating the arithmetic average of all distinct GVWR values less than or equal to 8,500 pounds available for that product line.

Special purpose vehicles. All automobiles with GVWR less than or equal to 8,500 pounds and all medium-duty passenger vehicles which possess special features and which the administrator determines are more appropriately classified separately from typical automobiles.
