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

If a driver feels drowsy while driving, the best action is to pull over safely and take a break or rest. Drowsiness significantly affects a driver's ability to concentrate, react, and make sound judgments on the road, leading to an increased risk of accidents. Stopping to rest allows the driver to regain alertness and ensures safety for themselves and others. Taking a break can involve a short nap or simply getting out of the vehicle to stretch and refresh.

The other choices, such as increasing speed to reach the destination faster, ignoring the feeling, or relying on caffeine to stay awake, are not effective solutions for combating drowsiness. Speeding can heighten the danger, while ignoring drowsiness can lead to serious consequences, as the driver may fall asleep at the wheel. Similarly, while caffeine might offer a temporary boost to alertness, it is not a substitute for proper rest and can lead to a false sense of security regarding one's ability to drive safely. Prioritizing rest is crucial for ensuring road safety.
