The use of any drug (the law does not distinguish between prescription, over-the-counter, or illegal drugs) which impairs your ability to drive safely is illegal. Check with your physician or pharmacist and read the warning label if you are not sure that taking the medication will affect your driving. Here are some facts:
- Most drugs taken for colds, hay fever, allergy, or to calm nerves or muscles can make a person drowsy.
- Medicines taken together or used with alcohol can be dangerous. Many drugs have unexpected side effects when taken with alcohol.
- Pep pills, “uppers,” and diet pills can make a driver more alert for a short time. Later, however, they can cause a person to be nervous, dizzy, and not able to concentrate. They can also affect the vision.
Any drug that “may cause drowsiness or dizziness” is one you should not take before driving. Make sure you read the label and know the effects of any drug you use.
