How can fatigue impact driving performance?

Answer: C — It can slow reaction times and impair decision-making

Fatigue can significantly impair driving performance in multiple ways, and one of the most critical effects is its ability to slow reaction times and hinder decision-making. When a driver is fatigued, the brain's cognitive functions are compromised. This means that the driver may not respond as quickly to unexpected situations on the road, such as sudden stops, pedestrians crossing, or changes in traffic signals. Additionally, decision-making becomes less sound due to fatigue. A tired driver may struggle to assess risks accurately or may not evaluate their options effectively, leading to poor choices that can result in accidents or dangerous situations. This makes it essential for drivers, especially those in law enforcement or public safety roles, to recognize the signs of fatigue and take appropriate action, such as resting or switching drivers, to ensure safety on the roads. The other options presented would not accurately represent the effects of fatigue; they suggest positive impacts or a false sense of capability that do not align with research on driver performance under fatigue.
