Red Seal Transport Trailer Technician Practice Exam

What safety feature prevents a trailer from becoming disconnected from the towing vehicle?

1. Hitch locks

2. Safety chains

3. Weight distribution bars

4. Brake controllers

The correct answer is: Safety chains

The correct answer is safety chains. Safety chains serve as a crucial safety feature that connects the trailer to the towing vehicle, providing an additional layer of security. In the event that the trailer somehow becomes unhitched from the towing mechanism, the safety chains prevent the trailer from completely separating from the towing vehicle. This ensures that even if the primary hitch fails, the trailer remains attached to the vehicle and can be controlled, reducing the risk of accidents or damage. Hitch locks, while they help secure the hitch connection when parked, do not function as a fail-safe during travel. Weight distribution bars serve to balance the load better and improve the handling of the towing vehicle and trailer but do not prevent disconnection. Brake controllers manage the trailer's braking system; they are essential for safe stopping but do not address the risk of disconnection itself.
