Can fatigue alter the driver's reaction time?

Correct answer

Yes, it increases reaction time.

Fatigue can alter the driver's reaction time by increasing it. Reaction time is the interval that elapses from when the driver perceives a stimulus until they react appropriately to it. Fatigue affects this reaction time in various ways: Reduced concentration capacity: Fatigue decreases the driver's attention and concentration, making it difficult to perceive and process environmental information adequately. Delayed decision-making: The mental tiredness associated with fatigue can slow down the driver's information processing and decision-making capabilities. Increased drowsiness: Fatigue can cause drowsiness, which can lead to microsleeps or brief, unintentional periods of sleep that interrupt the driver's ability to respond.
