A driver who is taking a non-prescription drug should:

  1. Read the labels on the drug before driving. ✓
  2. Drink alcohol instead.
  3. Continue to drive regardless of any warning labels.
  4. Drive only during daylight hours.

Answer: A. Read the labels on the drug before driving.

Read the label on a non-prescription drug before driving and check for warnings about its effects.

Why this is the answer

The handbook says drugs, including over-the-counter medications, can affect your ability to drive, sometimes as much as alcohol or worse. If you take a medication, even a cold or allergy remedy that is not prescribed, you should check the label for warnings about its effects. If you are unsure, the manual says to ask your doctor or pharmacist about driving while on the medication. That makes reading the label the first step before you decide whether it is safe to drive.

Why the other answers are wrong

Remember it

Check the label before you check your mirrors.
