You want to drive a vehicle with a trailer equipped with overrun braking. What do you have to check before beginning the journey?

When towing a trailer with overrun braking, it is essential to ensure safety and proper functionality before starting your journey. First, check that the connecting device is locked securely; this prevents the trailer from detaching while driving. Second, verify that the trailer's lighting system is working correctly, including brake lights and indicators, to communicate your actions to other road users and comply with traffic laws. Third, ensure the breakaway cable is properly attached; this cable activates the trailer brakes if it becomes disconnected from the towing vehicle, preventing uncontrolled movement. Together, these checks help maintain control and safety on the road.
