What should you do if you feel drowsy while driving?
- Open a window
- Stop for a short rest in a safe area ✓
- Turn up your radio
- Reduce speed
Answer: B. Stop for a short rest in a safe area
Pull off and stop for a short rest in a safe area, such as a well-lit rest stop or truck stop, and take a nap.
Why this is the answer
The handbook says you cannot trick your body into staying awake when you are drowsy; you need sleep. It suggests using well-lit rest stops or truck stops, locking your doors, rolling up the windows and taking a nap. It also says caffeine, radio volume and an open window may seem to help but do not replace sleep, especially when you are sleep deprived. That is why stopping safely for rest is the reliable response rather than trying to push on.
Why the other answers are wrong
- A. Open a window — Opening a window is one of the tricks the handbook mentions, but it says such tricks do not replace sleep when you are drowsy.
- C. Turn up your radio — Turning up the radio is also named as a trick that does not work as a substitute for sleep.
- D. Reduce speed — Slowing down is not presented as a cure for drowsiness; the handbook's advice is to stop safely and sleep.
Remember it
A safe, well-lit stop and a nap beat fresh air or a louder radio.
