What is the effect of fatigue on driving ability?

Answer: C — It can impair concentration and judgment

Fatigue significantly impairs both concentration and judgment, which are critical components of safe driving. When a driver is tired, their ability to focus on the road and react to unexpected situations diminishes. This lack of focus can lead to slower reaction times and an inability to process information quickly, which is essential for making sound driving decisions. Fatigue can also result in micro-sleeps—brief moments of sleep that can occur without the driver's awareness—further increasing the risk of accidents. Understanding the impact of fatigue on driving emphasizes the importance of being well-rested before getting behind the wheel. Even short trips or routine drives can be dangerous if the driver is not alert, highlighting that fatigue does not discriminate based on trip length or conditions. It's vital for drivers to recognize their own limits and take necessary breaks or avoid driving altogether if they are feeling tired.
