Question 12 of 20
Score: 0/0If a driver accidentally crosses the air lines when connecting to an older trailer, what could happen?
ExplanationIf the air lines are crossed, the trailer brakes might not release. On trailers without spring brakes, you may be able to move the vehicle, but the trailer brakes won’t function, which is very dangerous.
