Why should backing be done at the slowest practical speed?
- A.Slow backing is only for training yards
- B.Fast backing straightens the trailer sooner
- C.Speed does not affect backing risk
- D.A slow speed gives you time to stop before a small error becomes a collision, because your view behind is limited
Correct answer
D. A slow speed gives you time to stop before a small error becomes a collision, because your view behind is limited
Why
You are steering a vehicle whose largest blind area is directly behind it, so every extra mile per hour removes reaction time. Creeping speed, with stops to re-check when unsure, is the professional standard.
