Which of the following can also impair driving under Ontario law?
Show Answer & Explanation
Correct Answer: A. Prescription medications and some over-the-counter drugs
Legal medications — allergy pills, cold medicines, sleep aids, certain prescriptions — can impair driving. Always check the label for 'May cause drowsiness' and ask your pharmacist. Driving while impaired by legal drugs is still a Highway Traffic Act offence.
