Question: 1 / 400

What is the purpose of a breakaway switch?

To automatically lock the vehicle in place

To apply brakes on a trailer in the event of a trailer release from a vehicle

A breakaway switch is specifically designed to enhance safety in towing situations. Its primary purpose is to automatically activate the trailer's brakes in the event that the trailer becomes disconnected from the towing vehicle. When a trailer detaches, the breakaway switch is triggered, causing the trailer's brakes to engage and help to bring it to a stop, thereby preventing uncontrollable movement that could lead to accidents or damage.

Understanding this function highlights the importance of the breakaway switch in ensuring the safety of both the trailer and surrounding vehicles on the road. This safety mechanism is crucial for maintaining control over the trailer during a disconnection incident, ultimately reducing the risk of serious accidents. Other options do not address the specific function of a breakaway switch as effectively as this one does.
