The Influence of Drugs
Much of what has been said about alcohol also applies to drugs (both legally prescribed medicines and illegal drugs). Almost any drug can affect a person's driving ability. This is true of prescription drugs, drugs you can buy over-the-counter, and illegal drugs. Remember, even though you may feel fine, you may not be totally free of the adverse effects that can influence your driving.
- Most drugs taken for headaches, colds, hay fever, allergy, or to calm nerves can make a person drowsy and affect their driving.
- Carefully read and follow the directions about dosage and beware of side effects. Pay close attention to warnings about continued dosage.
- Drivers should ask their physician or pharmacist about how any medicine may affect their driving.
- Many drugs have unexpected effects when taken with alcohol. Drugs and alcohol should never be used at the same time.
Persons refusing these tests will be subject to the same license suspensions and revocations as for alcohol test refusals. Anyone convicted of manufacturing, possessing, or selling illegal drugs may also be subject to license suspension.
Make sure you read the label and know the effects of any drug you use. If it is a common drug, read the label. Any drug that "may cause drowsiness or dizziness" is one you should not take before driving. It is illegal to drive after taking any drug that impairs your driving. The law does not distinguish between prescription, over-the-counter, and illegal drugs.
