Question: 1 / 400

What is a common effect of fatigue on a driver's ability to drive?

Increased attention and faster reaction times

Decreased attention and slower reaction times

Fatigue significantly impacts a driver’s performance on the road by leading to decreased attention and slower reaction times. When a driver is fatigued, their ability to focus diminishes, which means they may miss crucial visual and auditory signals that are essential for safe driving. This lack of attention can result in overlooking traffic signs, failing to notice pedestrians, or not responding promptly to changing traffic conditions.

Additionally, reaction times are adversely affected when a driver is fatigued. Instead of responding quickly to emergencies or unexpected scenarios, their responses could be delayed, increasing the risk of accidents. Fatigue can also impair cognitive functions, making it more challenging to process information and make decisions quickly. Thus, the common effects of fatigue are directly linked to compromised driving abilities, underscoring the importance of being well-rested before getting behind the wheel.
