Your blind spot is the area of the road:
- You cannot see without moving your head. ✓
- Directly behind your vehicle.
- You see in your rearview mirror.
- You see in your side mirror.
Answer: A. You cannot see without moving your head.
Your blind spot is the area of the road you cannot see without moving your head.
Why this is the answer
The handbook talks about blind spots as the space a driver cannot see by looking in the mirrors alone, and it treats that unseen space as the reason a driver may not notice you. When you ride in someone's blind spot, that driver probably cannot see your car. If a mirror covered that space, it would not be a blind spot, so turning your head to check is what lets you see it.
Why the other answers are wrong
- B. Directly behind your vehicle. — The area directly behind you is what the rearview mirrors are there to show, so it is not the space you must turn your head to check.
- C. You see in your rearview mirror. — Anything you can see in your rearview mirror is already visible to you, which is the opposite of a blind spot.
- D. You see in your side mirror. — A side mirror shows you part of the road beside and behind you, so what it reveals is not hidden from you.
Remember it
If a mirror already shows it, it is not blind to you; the blind spot is what you only catch by turning your head.
