What can be the effects of fatigue on driving?

Answer: B — Impaired reaction times and decreased attention

Fatigue significantly impacts a driver’s ability to operate a vehicle safely. Impaired reaction times occur because a tired driver may find it difficult to respond quickly to sudden changes, such as a pedestrian crossing the road or another vehicle stopping unexpectedly. When a driver is fatigued, the brain’s processing speed declines, leading to slower responses to external stimuli. Decreased attention is another critical effect of fatigue on driving. As fatigue sets in, a driver may struggle to maintain focus on the road, becoming more prone to distractions and less likely to notice important signals, such as traffic signs or changes in the behavior of other drivers. This reduction in attention can lead to dangerous situations, as the driver may miss cues that require immediate action. Both of these factors can contribute to an increased risk of accidents, making it essential for drivers to recognize the signs of fatigue and take necessary precautions, such as resting before driving. Understanding these effects helps promote safe driving practices and awareness of one’s own limits while behind the wheel.
