What should you do if you're feeling drowsy while driving?

If you're feeling drowsy while driving, the best course of action is to pull over to a safe area and rest or switch drivers if possible. Drowsiness significantly impairs your ability to operate a vehicle safely, much like alcohol does. Stopping to rest helps ensure that you do not become a hazard to yourself and others on the road.

While opening the windows for fresh air may provide a temporary feeling of alertness, it does not address the underlying issue of fatigue and can sometimes lead to further distraction. Splashing water on your face might also give a fleeting sense of wakefulness but does not counteract the effects of sleepiness. Listening to loud music might keep you somewhat engaged, but it does not increase your alertness to a sufficient level to ensure safe driving. The safest and most effective action is to stop driving until you are fully awake and alert.
