What are the effects of fatigue on driving?

Answer: B — Impaired reaction time and decreased attention

Fatigue has significant negative effects on driving, most notably leading to impaired reaction time and decreased attention. When a driver is fatigued, their ability to process information slows down, which can delay how quickly they respond to hazards or changes in traffic conditions. This sluggishness in reaction can be critical in situations where split-second decisions are necessary to prevent accidents. Moreover, fatigue detracts from a driver's ability to maintain focus on the road and their surroundings. As attention wanes, drivers may become easily distracted or miss important visual and auditory cues, such as traffic signals or sounds from nearby vehicles. This combination of diminished response capability and lack of focus greatly increases the risk of collisions, making it essential for drivers to recognize the signs of fatigue and ensure they are well-rested before getting behind the wheel.
