What should be done if a driver starts to experience fatigue during a long trip?

When a driver begins to experience fatigue during a long trip, taking a short nap is the most effective course of action. Fatigue can severely impair a driver's ability to operate a vehicle safely, leading to slower reaction times, decreased alertness, and impaired decision-making. A brief nap allows the driver to rejuvenate and regain focus, which is essential for maintaining safety on the road.

While opening a window for fresh air or drinking caffeinated beverages might provide a temporary sense of alertness, they are not as effective as actually resting. Fresh air may not significantly counteract the tiredness, and although caffeine can enhance wakefulness, its effects can vary among individuals and may not last long. Continuously driving while fatigued can increase the risk of accidents, so prioritizing rest is critical to ensuring safety for both the driver and others on the road.
