What is the safest gear and speed control to use while backing under a trailer?
- A.The highest reverse gear to finish quickly
- B.Neutral, coasting backward
- C.Any gear, as long as you watch one mirror only
- D.A low reverse gear, slow and steady, with the ability to stop instantly
Correct answer
D. A low reverse gear, slow and steady, with the ability to stop instantly
Why
Low gear gives fine control and an instant stop if something is misaligned. Coupling is a precision task, not a speed task.
