Fatigue significantly impairs reaction time and decision-making, making it a substantial risk factor for drivers. When a person is tired, their cognitive functions are compromised, leading to slower response times when faced with driving challenges such as sudden obstacles, changes in traffic patterns, or the need to make quick decisions. This diminished capacity increases the likelihood of accidents, as a fatigued driver may misjudge distances, fail to react to traffic signals, or overlook critical surroundings.

Furthermore, lack of sleep or prolonged periods without taking breaks can induce a state similar to driving under the influence of alcohol, where both physical and mental faculties are severely impacted. Hence, recognizing that fatigue reduces a driver's alertness and the ability to process information effectively is crucial for maintaining safety on the road.
