What should a driver do if they feel drowsy while driving?

When a driver feels drowsy while driving, finding a safe place to pull over and rest or take a short nap is the most responsible course of action. Drowsiness significantly impairs a driver's reaction time, attention, and decision-making ability, much like alcohol intoxication. Continuing to drive while drowsy increases the risk of accidents, as the driver may fall asleep at the wheel or fail to respond adequately to changing traffic conditions.

Pulling over provides the opportunity to either take a brief rest or nap, which can significantly recharge a driver's alertness and cognitive functioning. This proactive measure helps ensure not only the safety of the driver but also the safety of others on the road.

The other options fail to address the vital need for alertness and safety. Continuing to drive, relying solely on caffeine, or employing distractions like opening windows or turning up the radio can mislead a driver into thinking they are fine to drive, ultimately leading to dangerous situations. These alternatives do not effectively remedy drowsiness and can result in impaired driving.
