Which statement about the effects of drugs on driving is supported by the material?

• A. All drugs have an effect on driving performance.
• B. No drugs affect driving performance.
• C. Some drugs have no effect on driving performance.
• D. Drug effects are limited to alcohol.

Answer: (A)

The main idea here is that drugs can influence driving performance. The material emphasizes that any drug—whether prescription, over-the-counter, or illegal—can alter brain function in some way, affecting alertness, reaction time, judgment, or coordination. Because of that, you should assume there could be some level of impairment whenever you’ve used any drug. Why this answer fits best is that it reflects the idea that all drugs have the potential to affect driving, even if the degree of impact varies. Some drugs may produce only mild effects for some people, while others can cause noticeable impairment, especially at higher doses or when combined with alcohol or other substances. This broader point helps explain why safe-driving guidance always stresses not driving after taking any drug until you know how it affects you. To keep the idea clear: driving impairment isn’t limited to alcohol. Many medications can slow reaction times, blur perception, or dull judgment, and different drugs can interact in ways that worsen impairment.
