Question 1 Report
A driver who has had several alcoholic drinks takes much longer than usual to brake when a hazard appears. Which effect of alcohol best explains the slower response?
Alcohol is a depressant, so it slows the activity of the nervous system and lengthens the time taken to respond to a hazard, which is why the driver takes much longer to brake. It does not speed up the nervous system, sharpen sight, or increase muscle strength; the slower response comes from its depressant effect slowing nerve impulse transmission.
