Why might the front of the tractor swing into an adjacent lane even when the trailer stays in its lane?
- A.The tractor is wider than the trailer
- B.Front swing is an illusion
- C.It only happens when speeding
- D.Turning the tractor wide to manage off-tracking moves the front end outward while the trailer cuts inward
Correct answer
D. Turning the tractor wide to manage off-tracking moves the front end outward while the trailer cuts inward
Why
A turn involves both ends moving in opposite directions relative to the lane. Watching only the trailer can put your front corner into the vehicle beside you.
