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

Before driving with a trailer that has overrun braking, German traffic rules require you to check three main things: First, make sure the connecting device is securely locked, so the trailer is safely attached to the towing vehicle. Second, check that the trailer’s lighting system, including brake lights, tail lights, and indicators, is working properly—this ensures you are visible and can communicate your actions to other road users. Third, verify that the breakaway cable is correctly attached; this safety device automatically activates the trailer’s brakes if it becomes detached while moving. Checking all three is essential for safety and is a legal requirement before setting off. If you follow this routine, you will comply with German regulations and travel more safely.
