you have improved night vision.
you drive with erratic speed or lane positioning.
you have a slower reaction time.

Explanation:

Analyze the question

The question asks to identify which option is NOT a way that drowsiness affects a driver.

Evaluate the options

• Wandering thoughts or daydreaming: This is a direct cognitive symptom of Driver Fatigue.
• Improved night vision: Drowsiness impairs sensory perception and pupil response, which decreases visual performance rather than improving it.
• Erratic speed or lane positioning: Fatigue leads to poor vehicle control, causing drifting and speed fluctuations.
• Slower reaction time: Sleepiness significantly delays cognitive processing and physical braking responses.

Identify the incorrect effect

Since drowsiness impairs physiological functions, it cannot lead to "improved night vision." Therefore, this option is the correct answer to the "NOT" question.

Answer:

• You have wandering thoughts or daydreaming.
• You have improved night vision. (Correct answer)
• You drive with erratic speed or lane positioning.
• You have a slower reaction time.
