Trailer TowingStandalone practice
Which trailer lights must operate from the towing vehicle?
The rear of a silver cargo trailer has two real red lower corner lamp housings, with unlit high marker lenses and a blank licence plate.
Correct answer: The trailer’s tail, brake and turn-signal lights
Why
Connect and test the trailer’s tail, brake and turn-signal lights before towing. A connected plug does not prove that every lamp is working.
