What does the guide say about driving a motor vehicle?
The answer
Answer: B. Driving a motor vehicle is a privilege. It takes skill and common sense, and alcohol, drugs or fatigue will cause your driving to suffer. It is your responsibility to know when you are not in shape to drive, even if the cause is medicine.
