When feeling drowsy while driving, pulling off the road at a safe location and resting is the most responsible course of action. Drowsiness significantly impairs your reaction time, judgment, and ability to concentrate, similar to the effects of alcohol. Continuing to drive while drowsy increases the risk of falling asleep at the wheel, which can lead to serious accidents.

Taking a break allows you to either rest for a few minutes or, if needed, to have a short nap. This is essential for regaining alertness and ensuring that you can drive safely afterward. Safe stopping points include rest areas, parking lots, or other designated areas where you are off the road and not in danger of being hit by other vehicles.

Although suggestions like opening a window for fresh air or playing loud music might provide a temporary distraction, they do not address the underlying issue of fatigue. These options can give a false sense of alertness but do not combat the impaired state caused by tiredness. Thus, the safest and most effective action when drowsy is to stop and rest.
