Backing
What the exam tests
Backing questions test the four basic rules: start from a good position, back slowly, use mirrors, and get out and look. The exam also tests helper use and blind-side backing.
Core rules
- Back only when necessary.
- Back toward the driver's side whenever possible.
- Use a helper; if you lose sight of the helper, stop.
- Get out and look (GOAL) before backing if unsure.
- Back slowly; steering is reversed when backing.
- Pull forward to correct a bad angle rather than forcing the maneuver.
Worked example
You must alley dock on the right side. Pull past the dock, set up so the trailer is angled toward the driver's side, and back slowly with a helper watching the right rear. If the trailer drifts left, pull forward and reset instead of oversteering. The reasoning is that a good start position reduces corrections and keeps the maneuver in the mirrors.
Traps that cost marks
- Backing blind side when a driver's-side approach is available.
- Relying on mirrors alone without checking clearance.
- Oversteering and then chasing the trailer.
- Continuing when the helper is out of view.
Exam tip
When in doubt, stop and pull forward. A reset is cheaper than a collision.
