Which of the following can impair your driving?
- Using illegal drugs
- Taking prescription medications
- Drinking alcohol
- All of the above ✓
Answer: D. All of the above
All of the above can impair your driving: illegal drugs, prescription medications, and alcohol.
Why this is the answer
The handbook says alcohol, illicit drugs, and even some prescribed drugs can reduce your ability to function safely behind the wheel. It also warns that medications such as antihistamines, sedatives, and some cold remedies can cause drowsiness and decreased alertness, and that certain medication combinations can affect driving. Because each listed item can make you less alert or less able to drive safely, the correct choice is all of them.
Why the other answers are wrong
- A. Using illegal drugs — Illegal drugs are not harmless here; the handbook lists illicit drugs such as cocaine and heroin as things that can reduce your ability to drive safely.
- B. Taking prescription medications — Prescription medications can also impair driving; the handbook warns that some prescribed drugs and medications can cause drowsiness or lower alertness.
- C. Drinking alcohol — Alcohol is clearly an impairing substance; the handbook includes alcohol among the things that can reduce your ability to function safely behind the wheel.
Remember it
If it can make you less alert, treat it as an impaired-driving risk, whether it comes from a bottle, a prescription, or an illegal source.
