What is one effect of fatigue on driving ability?

Answer: C — Slower reaction times

Fatigue has a significant negative impact on driving ability, one of which is the slowing of reaction times. When a driver is fatigued, their cognitive functions and physical capabilities are diminished. This can lead to decreased alertness and slower responses when it comes to making decisions or reacting to unexpected situations while driving. For instance, a fatigued driver might not notice a pedestrian stepping onto the street or might take longer to brake when a vehicle suddenly slows down in front of them. Slower reaction times can dramatically increase the risk of accidents, making it critical for drivers to be aware of their fatigue levels and take necessary actions, such as resting or avoiding driving, when feeling tired. The other options, such as improved focus, faster decision-making, or enhanced awareness, are not consistent with how fatigue affects a driver’s performance. Instead, fatigue typically leads to the opposite effects, underscoring the importance of being well-rested before getting behind the wheel.
