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 your driving ability: allergy medicine, marijuana, and cold remedies.

Why this is the answer

The handbook says many drugs can make it unsafe to operate a vehicle. That includes prescription drugs and over-the-counter medications for allergies and colds. It also says illegal drugs and controlled substances such as marijuana affect reflexes, judgment, and alertness. Mixing alcohol with allergy or cold medication can multiply the effects. Since each item named in the choices is covered as a drug that can impair driving, the all-of-these choice is correct.

Why the other answers are wrong

Remember it

Before driving, read the label and ask about side effects; anything that changes how you feel can change how you drive.
