If you begin to feel tired while driving, the best thing to do is to:

1. Get some coffee.
2. Open your window.
3. Stop driving. ✓
4. Turn on the radio.

Answer: C. Stop driving.

The best thing to do is stop driving.

Why this is the answer

The Florida handbook says directly to stop driving when you feel tired and not risk falling asleep at the wheel. It also explains that drowsy driving is dangerous because fatigue slows your thinking and reaction time, affects judgment and vision, and can cause nodding off or falling asleep. If you feel sleepy, the handbook says to find a safe place to stop and take a nap. That makes stopping the correct action, rather than trying to push through the tiredness.

Why the other answers are wrong

• A. Get some coffee. — The handbook does not list coffee as a fix for tired driving; it says to stop driving when you feel tired.
• B. Open your window. — Opening your window is not given in the handbook as a way to handle fatigue, and the instruction is to stop driving.
• D. Turn on the radio. — Turning on the radio is not described in the handbook as a cure for drowsiness; the stated action is to stop driving.

Remember it

When tiredness shows up, treat it as a stop signal, not something to cover up with a trick.
