How does fatigue impact a driver's ability to operate a vehicle?

Fatigue significantly impairs a driver's focus and slows reaction times, which can greatly increase the risk of accidents. When a driver is fatigued, their cognitive abilities are diminished, leading to decreased attention, hindered decision-making, and a lack of situational awareness. This state can also lead to slower mental processing, meaning that when a situation arises that requires immediate action, the driver may not respond promptly or appropriately.

Furthermore, fatigue affects the body physically, making it harder to perform necessary driving tasks, such as steering, accelerating, and braking, with the required precision. Therefore, recognizing fatigue as a serious hazard helps in understanding its profound impact on safe driving and the importance of being well-rested before operating a vehicle.
