To check your blind spot when changing lanes to the left, you should glance:
- Over your right shoulder.
- At your side mirror.
- Over your left shoulder. ✓
- At your rearview mirror.
Answer: C. Over your left shoulder.
When you change lanes to the left, glance over your left shoulder to check that area before you move.
Why this is the answer
The handbook explains that blind spots sit near the left and right rear corners of your car, where neither your mirrors nor your peripheral vision reach. It says that before changing lanes, passing, or making certain turns, you should turn your head to confirm those areas are clear. Your left rear corner is the spot your left-side mirror misses, so turning your head to the left is what actually covers it before you slide over.
Why the other answers are wrong
- A. Over your right shoulder. — Looking over your right shoulder covers the right rear corner, which is the wrong side when you are moving left.
- B. At your side mirror. — The side mirror is exactly what leaves the blind spot unseen, so it cannot confirm that area is clear.
- D. At your rearview mirror. — The rearview mirror shows what is behind you, not the left rear corner the handbook describes as a blind spot.
Remember it
Turn your head the same way you are moving — left lane, left shoulder.
