In every state, it is a crime for a driver to operate a vehicle while impaired by the effects of alcohol or drugs. The specific offense may be called driving under the influence (DUI), driving while intoxicated (DWI), operating under the influence (OUI), and even operating a motor vehicle intoxicated (OMVI). Whatever the specific title, DUI laws make it unlawful for a person to operate a car, truck, motorcycle, or commercial vehicle if:
– The driver’s ability to safely operate the vehicle is impaired by the effects of alcohol, illegal drugs, prescribed medications such as painkillers, or even over-the-counter medications such as antihistamines; or
– The driver is intoxicated at a level above established DUI standards, such as blood-alcohol concentration (BAC).
