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.

If you start feeling tired while driving, the best thing to do is stop driving.

Why this is the answer

The Texas handbook tells drivers not to drive when they are tired or not feeling well, and it says never to force yourself to drive. It also warns against driving while tired at all. Since the handbook's guidance is to avoid driving in that condition, the safe response is to stop driving rather than try to push through. Coffee, fresh air, or the radio may seem like quick fixes, but the passages do not support relying on them when you are tired.

Why the other answers are wrong

Remember it

Think of tiredness as a red light for driving, not a reason to reach for a pick-me-up.
