What kinds of drugs can affect your driving ability?

  1. Allergy medicine
  2. Marijuana
  3. Cold remedies
  4. All of these choices ✓

Answer: D. All of these choices

All of these choices can affect driving ability: allergy medicine, marijuana, and cold remedies.

Why this is the answer

The manual lists many prescription and over-the-counter medications and illegal substances as drugs that can change your ability to drive, with effects like alcohol or worse. It specifically tells you to check the label on a cold or allergy remedy, even one you do not need a prescription for, and warns about driving while impaired by marijuana/cannabis. Because each listed item is an example of a drug the manual says can impair driving, the choice covering all of them is correct.

Why the other answers are wrong

Remember it

Cold and allergy remedies belong on the same driving-warning list as marijuana when it comes to your ability to drive.
