The traditions of St. Patrick’s Day, such as corned beef and cabbage and shamrocks, accompany the tradition of drinking Irish beer and/or whiskey. These days, prescription drugs, over-the-counter medications and illegal drugs may cause impairment alone or in combination with each other and/or with alcohol.

In every State and the District of Columbia, impaired driving is illegal. Whether by drugs, legal or illegal, alcohol, or a combination of drugs and alcohol, impaired driving leaves the driver, their passengers, and other road users at risk. In NHTSA’s National Roadside Survey conducted in 2013-2014, 20% of drivers surveyed tested positive for potentially impairing drugs.
