What may happen when alcohol is taken with prescription, over-the-counter, or illegal drugs?
Correct answer: A – The drug's effects may become unpredictable
Alcohol and drugs should not be taken together because alcohol can have an unpredictable effect on other substances. Drugs may impair reflexes, judgment, vision, and alertness in ways similar to alcohol. A driver should not expect one substance to cancel or reduce the effects of the other.
