A driver who is taking a non-prescription drug should:
- Read the labels on the drug before driving. ✓
- Drink alcohol instead.
- Continue to drive regardless of any warning labels.
- Drive only during daylight hours.
Answer: A. Read the labels on the drug before driving.
Before driving, read the label on any non-prescription drug.
Why this is the answer
The handbook tells drivers that many over-the-counter medicines can make you drowsy, and that antihistamines, cold preparations, and sleep-promoting medicines deserve care. It also says any drug might change your driving ability. Because the label is where those warnings appear, the safe step before driving is to read it. If you are unsure about a drug or a mix of drugs, the handbook directs you to ask a doctor or pharmacist.
Why the other answers are wrong
- B. Drink alcohol instead. — Drinking alcohol instead is wrong because the handbook describes alcohol as a depressant that harms coordination and judgment and warns that mixing it with drugs can be hazardous.
- C. Continue to drive regardless of any warning labels. — Driving regardless of warning labels is wrong because the handbook says many over-the-counter drugs cause drowsiness and any drug might affect your ability to drive.
- D. Drive only during daylight hours. — Driving only during daylight hours is wrong because the passages tie drug effects to drowsiness and impaired skills, not to a particular time of day.
Remember it
Check the label before you turn the key; if the warning is unclear, ask a pharmacist.
