What effect does fatigue have on driving ability?

Answer: C — Can impair judgment and reaction time

Fatigue can significantly impair a driver's judgment and reaction time, making it a critical factor in road safety. When a driver is fatigued, their cognitive functions are diminished, which affects their ability to process information, make decisions, and respond quickly to changing driving conditions. This impairment is similar to that caused by alcohol consumption, as both can lead to slower reactions and poor decision-making. Research shows that tired drivers may struggle to stay focused, misjudge distances and speeds, and even experience lapses in attention, which can result in dangerous driving situations. It's essential for drivers to recognize the signs of fatigue and take necessary breaks to ensure they remain alert and responsive while on the road. Understanding the serious impact of fatigue on driving ability highlights the importance of getting adequate rest before undertaking long drives or commutes.
