Show answer & explanation

Correct answer: C. The trailer could become detached.

Before towing a trailer, a driver should ensure that the tow hitch has sufficient ground clearance. If this hits the road, for example when travelling over a humpbacked bridge, there is a danger that the trailer will become detached. Drivers should also plan and carry out their journey with an awareness of this risk.
