What term refers to a freight vehicle with undercarriage wheels or mounted on a chassis used for highway transportation?

• A. Tractor
• B. Chassis
• C. Trailer
• D. Container

Answer: (C)

In highway freight, the unit that actually carries the cargo and has its own wheels is the trailer. It’s the load-carrying piece that is towed behind a separate power unit (usually a tractor) and can be a semi-trailer that connects to the tractor via a fifth wheel. The trailer is the correct term because it describes the towable freight vehicle used on highways. A tractor is the power unit that pulls the trailer, not the cargo-carrying vehicle on its own. A chassis is just the supporting frame structure, not the complete towable vehicle. A container is the cargo box; it can ride on a trailer but isn’t the vehicle itself.
