When driving in a low-visibility situation, you should:
- Decrease your following distance.
- Increase your following distance. ✓
- Drive as if it is a high-visibility situation.
- Tailgate the car in front of you.
Answer: B. Increase your following distance.
Increase your following distance when driving in low visibility.
Why this is the answer
The Florida handbook lists low visibility, including dusk, dawn, nighttime and fog, among the situations where you should increase your following distance. It also explains that a larger gap gives you more time to react and helps you avoid hitting the vehicle ahead. So when visibility is poor, you should open up the space in front of you rather than close it.
Why the other answers are wrong
- A. Decrease your following distance. — Decreasing the gap is the opposite of the handbook's guidance and leaves less room to react.
- C. Drive as if it is a high-visibility situation. — The handbook specifically treats low visibility as a condition that calls for more following distance, not normal high-visibility spacing.
- D. Tailgate the car in front of you. — Tailgating means following too closely, which the handbook connects with rear-end collisions and says to avoid by keeping enough space.
Remember it
Think "less sight, more space": the worse the visibility, the larger the gap you leave.
