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

After coupling a multiple-axle trailer to an automatic trailer coupling in Germany, it is essential to ensure safety by checking two key points: the coupling pin must be fully engaged, and the position of the control pin must be correct. The coupling pin secures the trailer to the towing vehicle, preventing accidental separation while driving. The control pin indicates whether the coupling is properly locked. Checking the slope angle of the trailer’s towing fork is not required at this stage. Always verifying these components helps prevent accidents and ensures the trailer is safely attached before moving.
