Correct answer
The trailer cannot move accidentally.
Immobilise the trailer so that it cannot move accidentally when separated from the towing vehicle. Before uncoupling, follow the manufacturer’s procedure: use the trailer brake if fitted, and the appropriate chocks and support. The towing vehicle’s brake alone no longer holds the trailer after separation. Do not wait until releasing the coupling to secure a trailer that can roll.
