Which of the following is advisable when feeling tired while driving?

When feeling tired while driving, stopping to take a short nap is the most advisable action. Sleepiness has a significant impact on a driver's ability to operate a vehicle safely, leading to slower reaction times, impaired judgment, and an increased risk of accidents. Taking a brief nap can help restore alertness and enhance overall driving performance.

In contrast, increasing speed to reach the destination faster can lead to reckless driving, heightening the risk of accidents. Relying on energy drinks is not a reliable solution, as the short-term boost they provide does not effectively counteract the need for actual sleep, and they may cause a crash in energy levels later on. Continuing to drive while feeling tired, even with an intention of being more cautious, can be highly dangerous, as fatigue adversely affects decision-making and reaction times, making it difficult to respond appropriately to road conditions and hazards.
