You want to couple on a multiple-axle trailer. What must you ensure?

When coupling a multiple-axle trailer, it is important to follow specific safety measures to prevent accidents. First, the trailer must be secured against rolling away to avoid unintended movement during the coupling process. This is usually done by applying the parking brake or using wheel chocks. Second, no one should remain between the motor vehicle and the trailer to prevent injury in case the vehicle moves unexpectedly. These precautions are essential because coupling requires precise alignment and any movement or presence between the vehicle and trailer can lead to serious accidents. The brake lines should be connected after the trailer is properly docked, so connecting them just before docking is not correct. Remembering these key safety steps helps ensure a safe and smooth coupling procedure.
