In Danish traffic rules, what does the 'safety breakaway cable' (sikkerhedswire / springwire) on a trailer do?
Answer and explanation
Correct answer: B. Activates the trailer's emergency brakes if the trailer accidentally detaches from the tow ball while driving
- Step 1: The breakaway cable is looped around the tow bar bracket; if the trailer disconnects from the ball, the tension pulls the handbrake lever of the trailer before the cable snaps. Answer: Activates the trailer's emergency brakes if the trailer accidentally detaches from the tow ball while driving. Why not the others: Electrical power is delivered via the 7-pin or 13-pin cable, jockey wheels support the tongue, and wheel clamps prevent theft.
