Impaired Driving

Motor vehicle crashes involving alcohol-impaired drivers kill one person every 45 minutes in the United States. That’s 32 people every day.
We know a lot about the harmful effects of alcohol-impaired driving but less about the burden of drug-impaired driving. Regardless, driving while impaired by any substance is dangerous and illegal.
Thankfully, there are effective measures that can help prevent injuries and deaths from impaired driving.
Driving while impaired by any substance can be deadly. Impaired driving happens when someone operates a vehicle while impaired by substances such as marijuana, illicit drugs, some prescription or over-the-counter medicines, and/or alcohol.
