Question 5852
How does alcohol affect driving?
- It can reduce reaction time.
- It can promote the onset of drowsiness.
- It can delay the onset of drowsiness.
Show answer and explanation
Correct answer: It can promote the onset of drowsiness.
Alcohol slows down your nervous system and lowers your alertness, making fatigue and drowsiness more likely, as with the man in the image, who is yawning next to his drink. It also increases reaction time rather than reducing it.
