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

When coupling a multiple-axle trailer to an automatic trailer coupling, it's essential to ensure the safety and functionality of the connection.

1. The coupling pin must be fully engaged to prevent any separation of the trailer while driving. If the coupling pin is not secured properly, it can lead to dangerous situations on the road.

2. The position of the control pin is equally important because it indicates that the coupling mechanism is functioning correctly. A misaligned or incorrectly positioned control pin can compromise the security of the trailer connection.

Checking these two aspects is crucial according to German traffic regulations, as they directly relate to the safe transport of loads and the elimination of risks associated with trailer detachment. Ensuring both components are properly checked helps maintain road safety for everyone.
