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, it is essential to check that the coupling pin is fully engaged and the position of the control pin. This ensures that the trailer is securely attached and that the coupling mechanism has locked properly. Both checks help prevent accidental detachment while driving, which is a key safety requirement in German traffic regulations. Checking the slope angle of the trailer’s towing fork is not necessary for this procedure, so your selections were correct. Being thorough with these checks increases road safety for you and others.
