Many substances can impair driving, including alcohol, some over-the-counter and prescription drugs, and illegal drugs.
Alcohol, marijuana, and other drugs impair the ability to drive because they slow coordination, judgment, and reaction times.
Using two or more drugs at the same time, including alcohol, can amplify the impairing effects of each drug a person has consumed.
Some prescription and over-the-counter medicines can cause extreme drowsiness, dizziness, and other side effects. Read and follow all warning labels before driving, and note that warnings against “operating heavy machinery” include driving a vehicle.
Impaired drivers can’t accurately assess their own impairment – which is why no one should drive after using any impairing substances.
Remember: If you feel different, you drive different.
