Under what condition are prescription drugs allowed while driving?

• A. Only if you are not taking any other medications.
• B. Only if the drug is over-the-counter.
• C. Only if you are not fatigued.
• D. The doctor says the drug will not affect safe driving ability.

Answer: (D)

Prescription drugs are allowed only if a doctor has determined that the medication will not affect your safe driving ability. Medications can alter reaction time, coordination, or judgment, and people react differently to the same drug. The doctor’s assessment is the authoritative signal that you can drive safely with that prescription. Even if a drug is prescribed or you feel fine, it can still impair you, so the key factor is the professional’s evaluation that it won’t affect driving. The other ideas don’t guarantee safety—taking other medications or the drug being over-the-counter doesn’t automatically make driving safe, and not feeling fatigued doesn’t rule out impairment from some drugs.
