How does fatigue affect driving?

Fatigue significantly impairs driving performance in various ways. When a driver is fatigued, their attention to the road diminishes, which means they may miss crucial signals or changes in traffic conditions. Additionally, fatigue leads to slower reaction times; the driver may not respond promptly to unexpected situations, such as a sudden stop by the vehicle ahead or a pedestrian crossing the road. Moreover, decision-making is compromised, as a fatigued driver may struggle to weigh options or make quick judgments—potentially leading to dangerous driving choices.

The complexities of driving demand full cognitive function and alertness, both of which are diminished when a driver is fatigued. Therefore, it's essential to prioritize rest and recognize the signs of fatigue to ensure safe driving.
