What should you do if you feel drowsy while driving?

When you feel drowsy while driving, the best course of action is to stop and take a break. This response is crucial because fatigue impairs your attention, reaction time, and decision-making abilities, all of which are essential for safe driving. By stopping, you allow yourself to rest and recover, which significantly reduces the risk of being involved in an accident due to drowsiness.

Turning on the radio may provide temporary distraction but does not address the underlying issue of fatigue, and it can lead to overconfidence in your ability to stay alert. Driving faster could further increase the risk as it does not rectify the problem of drowsiness; it only heightens the danger. Opening a window may introduce fresh air but is unlikely to provide the necessary alertness to drive safely when experiencing fatigue. Taking a break is the only reliable way to ensure that you remain safe while on the road.
