When driving in fog, you should use your:
- Low beam headlights. ✓
- High beam headlights.
- Parking lights.
- Hazard flashers.
Answer: A. Low beam headlights.
Use low beam headlights when driving in fog.
Why this is the answer
The Florida handbook's low-visibility section tells you to drive with your headlights on low beam. It explains that high beams reflect off the fog and make visibility worse, so low beams are the setting to use when fog, smoke, or heavy rain cuts your view. The same section says parking lights cannot take the place of headlights. That is why low beam headlights are the correct choice in fog.
Why the other answers are wrong
- B. High beam headlights. — High beams are wrong because the handbook says they reflect off fog and impair visibility even more.
- C. Parking lights. — Parking lights are wrong because the handbook says they are not a substitute for headlights in low visibility.
- D. Hazard flashers. — Hazard flashers are not given as the lighting choice for driving in fog in the handbook; it directs you to use low beam headlights.
Remember it
Think low beam for low visibility: fog sends high beams back at you.
