Show answer & explanation
Correct answer: 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.
