Are Small Vehicles Considered a CMV?

Home / ELD / Are Small Vehicles Considered a CMV?


The answer to this question on ELD exemptions is related to the Gross Vehicle Weight Rating (GVWR) and Gross Combination Weight Rating (GCWR).

Gross Vehicle Weight Rating (GVWR) Vs. Gross Combination Weight Rating (GCWR):
GVWR is defined as the maximum operating weight of a vehicle as set by the manufacturer including the vehicle itself (chassis, body, engine, engine fluids, fuel and accessories), including the weight of the driver, passengers, and cargo. GCWR is the manufacturer’s specified maximum weight for a vehicle that is towing a trailer (includes the weight of the vehicle, driver, passengers and cargo, plus the attached trailer with load).

Vehicles are often specialized to deliver different types of goods. Semi-trailers can be outfitted with various trailers such as box trailers, flatbeds, car carriers, tanks, and other specialized trailers. Dump trucks and concrete mixers are examples of vehicles specialized for delivery of specific types of goods.

If the GVWR/GCWR of the truck, load, and any trailer (inclusive of load) you are transporting at any point in time exceeds the 10,001 pounds or greater definition of CMV found in §390.5, it will become a CMV. That vehicle would be regulated empty or loaded.

When you find your vehicle, even if it’s a pickup, is now classified as a CMV, the driver of the vehicle must comply with the hours of service regulations. During the time you meet the criteria of a CMV, you need to obey all regulations, which may include stopping at roadside inspection stations or having U.S. Department of Transportation (U.S. DOT) markings on the side of the truck.
