Tennessee Permit Practice Test

Alcohol in any concentration is:

1. A stimulant

2. A depressant

3. Neither of the above

4. Both A and B

The correct answer is: A depressant

Alcohol is classified as a depressant because it slows down the central nervous system. It works by depressing the activity of the brain, leading to a decrease in motor coordination, reaction time, and cognitive function. This is why it is important to understand that alcohol consumption can impair judgment and physical abilities, making it dangerous to operate a vehicle or machinery under its influence.
