What is the impact of driving fatigued?

Answer: B — It decreases awareness and slows reaction time

Driving while fatigued significantly decreases awareness and slows reaction time. Fatigue impairs cognitive functions, making it harder for a driver to process information and react to unexpected situations on the road. When a driver is tired, their focus diminishes, which can lead to missed road signs, delayed responses to changes in traffic, and an overall lack of vigilance. This impaired state can be likened to the effects of intoxication, where judgment and reflexes are adversely affected. Therefore, selecting the option that highlights these negative effects accurately reflects the dangers of driving while fatigued.
