C+EDifficulty 2/5

Before driving an articulated combination or towing a heavy trailer, which check concerns the secure connection between the vehicles?

Correct answer

The coupling lock and its connections

Check that the coupling is correctly closed and locked and its connections secured, following the manufacturer’s procedure. Checking documents, the route or the seat can also be necessary, but does not verify the physical connection between the vehicles. Do not move off if there is doubt about the coupling’s closure or condition.
