If your trailer starts to skid, what is the most reliable way to notice it early?
Correct answer: Watching for it in your mirrors.
Answer options
- AWatching for it in your mirrors Correct
- BNoticing that a tire has failed
- CFeeling the brakes engage
Why
A trailer that starts to slide often gives no warning you can feel in the cab, so the mirrors are where you will spot it first. Check them whenever you brake hard to make sure the trailer is still tracking behind you.
