How does fatigue impact driving performance?

Fatigue has a significant negative impact on driving performance by reducing alertness and overall decision-making capabilities. When a driver is fatigued, their cognitive functions, including attention, judgment, and reaction time, become impaired. This fatigue can lead to slower responses to unexpected events, compromised ability to assess road conditions, and diminished capacity to process information effectively. As a result, a fatigued driver is more prone to errors, which can increase the risk of accidents.

In contrast to the correct answer, other options communicate misconceptions about the effects of fatigue. Some may underestimate the risks associated with fatigue, incorrectly thinking it has no impact on performance or only affects physical capabilities, ignoring how it impairs cognitive processes vital for safe driving. Understanding the extensive implications of fatigue on both attention and decision-making is crucial for maintaining road safety.
