NHSA Module 9 Practice Test

Alcohol can impair a person after how many drinks?

Two drinks One drink Three drinks Four drinks

Correct Answer:

One drink

Explanation:

Alcohol is a depressant that slows brain function, so its effects begin as soon as it enters the bloodstream. Even a single drink can impair thinking, reduce coordination, and slow reaction times, which means impairment can occur after just one beverage. How strong the impairment feels depends on factors like body weight, whether you’ve eaten, and your individual tolerance, but many people notice effects after one drink. The other options imply you must have more drinks for impairment to show up, which isn’t accurate because risk starts with the first drink. For safety, assume any amount of alcohol can affect your ability to perform tasks that require focus and quick responses, such as driving, and plan accordingly.
