What is the best way to check whether your trailer is staying behind you properly while driving?
- A.Listen for the trailer tires over the radio
- B.Look only at the left mirror once each mile
- C.Check both mirrors regularly so you can spot the trailer drifting, swaying, or swinging early
- D.Wait until you feel the trailer push the tractor
Correct answer
C. Check both mirrors regularly so you can spot the trailer drifting, swaying, or swinging early
Why
By the time you feel a trailer problem through the seat, it is usually well developed. Regular mirror checks show you the trailer's behavior while a sway or drift is still small and correctable.
