To avoid collisions with vehicles in your blind spots, you should:
- Quickly turn your head to see if your blind spot is clear before changing lanes. ✓
- Adjust your rearview mirrors every few minutes.
- Honk your horn right before turning or changing lanes.
- None of the above.
Answer: A. Quickly turn your head to see if your blind spot is clear before changing lanes.
You should quickly turn your head to check that your blind spot is clear before changing lanes.
Why this is the answer
The Florida handbook explains that blind spots sit near the left and right rear corners of your vehicle and cannot be seen in your rear-view mirrors or with peripheral vision. Before changing lanes on a highway, passing on any road, or making certain turns, it says to turn your head to make sure those areas are clear. That head check is how you avoid moving into a space where a vehicle is hidden from your mirrors.
Why the other answers are wrong
- B. Adjust your rearview mirrors every few minutes. — Adjusting your rearview mirrors every few minutes does not solve the problem, because the handbook says blind spots are areas you cannot see in those mirrors.
- C. Honk your horn right before turning or changing lanes. — Honking right before turning or changing lanes does not tell you whether a vehicle is hidden beside you, and the handbook does not instruct you to honk for that purpose.
- D. None of the above. — This is wrong because the handbook directly tells you to turn your head to check the blind spot before moving into another lane.
Remember it
Mirrors show what is behind you; a quick head turn shows the corners they miss.
