What is one of the main risks associated with driving under the influence of fatigue?

Driving under the influence of fatigue significantly impairs a driver's ability to respond effectively to changing conditions on the road. When fatigued, a driver's mental and physical reactions are slower, leading to a decreased reaction time. This slowing down can prevent a driver from responding adequately to vital situations, such as sudden stops, obstacles, or changes in traffic signals.

In contrast, options that suggest improved decision-making, alertness, or focus are inaccurate representations of a fatigued state. Fatigue leads to a diminished capacity to process information swiftly and accurately, ultimately compromising the driver's safety and that of others on the road.
