There are various criminal charges for operating a motorized, electric, or otherwise-powered transportation device on public roadways or waterways while under the influence of or intoxicated by drugs or alcohol, as defined by state law. DUI, DWI, OUI, OWI, and BUI—driving under the influence, driving while intoxicated, operating under the influence, operating while intoxicated, and boating under the influence—are some of the common names for such impaired-driving or impaired-operating criminal offenses.

Laws regarding the definitions and names of such alcohol and drug-related driving offenses vary from state to state and are usually located in a state’s statutes—often in the penal code or criminal code.

In Nevada, the primary statute governing the operation of vehicles under the influence of alcohol or drugs is Nevada Revised Statutes (NRS) 484C. DUI (Driving Under the Influence) is the term used for such offenses in this state. Under NRS 484C.110, it is illegal for a person who is under the influence of alcohol, a controlled substance, or a prohibited substance, or who has a blood alcohol concentration of 0.08% or higher, to be in actual physical control of a vehicle on a highway or on premises to which the public has access. The law also covers offenses involving the operation of watercraft under the influence, known as BUI (Boating Under the Influence), under NRS 488.410. Penalties for DUI/BUI offenses in Nevada can include fines, jail time, community service, DUI school, and the suspension of driving privileges. The specific consequences depend on the number of offenses and the severity of the incident, such as whether it resulted in injury, death, or property damage.
