How does fatigue affect a driver's ability?

Answer: C — It can impair attention and reaction times

Fatigue significantly impairs a driver's attention and reaction times, making option C the correct choice. When a person is fatigued, their cognitive functions are compromised, leading to slowed reaction times and diminished ability to focus. This can result in missed signals, delayed responses to sudden changes in traffic or road conditions, and an overall increase in the likelihood of accidents. Furthermore, tired drivers may experience a reduction in their ability to process information effectively, which crucially impacts decision-making on the road. The state of fatigue can mimic the effects of alcohol consumption, leading to impaired judgment and a higher probability of engaging in risky behaviors, such as speeding or not adhering to traffic signals. Recognizing the dangers of driving while fatigued is essential for maintaining road safety and ensuring the well-being of all road users.
