What must be checked after you have coupled a multiple-axle trailer to an automatic trailer coupling?

The correct checks after coupling a multiple-axle trailer are essential for safety and compliance with German traffic laws.

1. The coupling pin must be fully engaged: This ensures the trailer is securely attached to the towing vehicle. If the coupling is not fully engaged, it can result in the trailer detaching while driving, leading to dangerous situations.

2. The position of the control pin: Checking the control pin is crucial for confirming that the coupling mechanism is locked in place. If it is not in the correct position, the trailer's connection may be compromised, increasing the risk of accidents.

Both of these checks are vital to ensure safe towing, as outlined by regulations that mandate stringent safety measures when operating vehicles with trailers. The omission of checks related to the control pin can lead to severe safety hazards on the road.
