What should you do if you feel sleepy while driving?

When you feel sleepy while driving, the safest and most effective action is to get some sleep. Fatigue can significantly impair your reaction times, judgment, and overall ability to drive safely, much like alcohol can. Pulling over to a safe location and allowing yourself to rest can prevent potential accidents and ensure that you are alert when you resume driving.

Turning up the radio or rolling down the window might provide a temporary distraction or a brief sense of alertness, but they do not address the underlying issue of fatigue. Drinking coffee can offer a short-term boost in alertness due to caffeine; however, it is not a substitute for rest and may not be effective for everyone. The only reliable solution to drowsiness on the road is to take a break and sleep if possible.
