Florida law requires you to use headlights:

  1. To get the attention of vehicles surrounding you.
  2. During a clear day.
  3. Between sunset and sunrise. ✓
  4. If you are driving while tired.

Answer: C. Between sunset and sunrise.

Florida law requires you to use headlights between sunset and sunrise.

Why this is the answer

The handbook's night-driving section states that Florida law requires headlights from sunset to sunrise. It also explains that at night you cannot see as far ahead and oncoming glare can make vision worse. That is why the rule is tied to those hours, not to clear weather or how tired you feel. The passage does not describe headlight use as a way to get other drivers' attention, so the legal trigger it gives is the time of day.

Why the other answers are wrong

Remember it

Hook it to the sky, not your mood: sunset on, sunrise off.
