Which of the following statements about blind spots is true?
- They are eliminated if you have one outside mirror on each side of the vehicle.
- Large trucks have bigger blind spots than most passenger vehicles. ✓
- Blind spots can be checked by looking in your rearview mirrors.
Answer: B. Large trucks have bigger blind spots than most passenger vehicles.
Large trucks have bigger blind spots than most passenger vehicles.
Why this is the answer
The handbook says large vehicle and truck drivers have large blind spots, called No Zones, where your vehicle can disappear from their view. It also explains that every vehicle has blind spots at the sides and slightly behind the driver, and those areas are not covered when you look straight ahead or use the mirrors. Because truck blind spots are described as large, the choice about trucks having bigger blind spots than most passenger vehicles is the supported one. The other choices treat mirrors as enough to remove or check blind spots, which the handbook does not say.
Why the other answers are wrong
- A. They are eliminated if you have one outside mirror on each side of the vehicle. — Outside mirrors on both sides do not eliminate blind spots; the handbook says blind spots are areas you cannot see even when using the mirrors and tells drivers to look over their shoulders.
- C. Blind spots can be checked by looking in your rearview mirrors. — Rearview mirrors alone do not check blind spots; the handbook says to look over your right and left shoulders out of the side windows.
Remember it
Think No Zones: big vehicles hide you in their large blind spots.
