What is the safe sequence for changing lanes?
- A.Steer first, then signal, then check mirrors
- B.Check mirrors and signal only after moving
- C.Speed up and move before anyone can block you
- D.Check mirrors, signal, check the blind spot area, and move over gradually when clear
Correct answer
D. Check mirrors, signal, check the blind spot area, and move over gradually when clear
Why
Mirrors first tell you the move may be possible, the signal announces it, and a blind-spot check catches what mirrors miss. Moving gradually gives others time to react if you missed something.
