Question: 1 / 400

What is the function of a trailer's brake system?

To provide power to the trailer's electrical system

To slow down or stop the trailer when the tow vehicle brakes

The primary function of a trailer's brake system is to slow down or stop the trailer when the tow vehicle brakes. This system is vital for safety, as it ensures that both the tow vehicle and the trailer respond proportionately when braking, helping to prevent skidding or loss of control. When the vehicle's brakes are engaged, the trailer's braking system activates, allowing for coordinated stopping that maintains stability and control throughout the maneuver.

This function is particularly important because trailers, especially heavy ones, can create significant momentum when being towed. Without an effective braking system, the trailer can push the tow vehicle forward during rapid deceleration, increasing the risk of accidents. Therefore, a well-designed braking system on a trailer is essential for maintaining safe operation on the road.
