Which describes a CMV?

• A. A motor vehicle or combination of vehicle used in commerce to transport passenger or property
• B. A regular passenger car used for commuting
• C. A vehicle used for personal recreation
• D. Any vehicle with a GVWR over 10,000 lbs

Answer: (A)

The main idea here is what defines a commercial motor vehicle (CMV). A CMV is a motor vehicle or a combination of vehicles that is used in commerce to transport passengers or property. That “used in commerce” part means the vehicle is involved in a business or trade activity—think delivery trucks, taxis, school buses, or tractor-trailers used to haul goods for a company.

That’s why the best description is the one that states a CMV is a motor vehicle or a combination of vehicles used in commerce to transport passengers or property. The other options miss a key point: a regular passenger car used for commuting isn’t used in commerce; a vehicle for personal recreation isn’t either; and while many CMVs do have a GVWR over 10,000 pounds, simply exceeding that weight doesn’t by itself make a vehicle a CMV unless it’s used in commerce.
