Question: 1 / 400

What is the purpose of a breakaway cable?

to connect the trailer to the tow vehicle

as a safety device for the trailer braking system

The breakaway cable serves a crucial safety function within a trailer's braking system. Its primary purpose is to activate the trailer's brakes in case the trailer accidentally detaches from the tow vehicle while on the road. When the trailer becomes separated, the breakaway cable pulls a pin from the trailer's braking system, which engages the brakes to slow down and stop the trailer safely. This feature significantly reduces the risk of accidents, as it prevents the trailer from rolling away uncontrollably.

In contrast, connecting the trailer to the tow vehicle is achieved through the hitch mechanism, while providing security against theft is typically managed through locks or locking devices, and towing heavier loads does not directly relate to the function of the breakaway cable. The emphasis on safety highlights why the braking system's role via the breakaway cable is paramount.
