How does off-tracking change when backing a trailer?
- A.Backing eliminates off-tracking
- B.The trailer moves opposite the tractor's steering input at first and its path must be watched in the mirrors as it swings
- C.The trailer follows the front wheels exactly in reverse
- D.Mirrors cannot show a backing trailer
Correct answer
B. The trailer moves opposite the tractor's steering input at first and its path must be watched in the mirrors as it swings
Why
In reverse, small steering inputs produce growing trailer angles. Watching the trailer's actual path, not just the tractor's, is how you keep it off curbs and away from objects.
