A person may be convicted of impaired driving under either the Driving Under the Influence (DUI) statute or the Actual Physical Control of a Vehicle While Under the Influence (PC) statute. A person is guilty of DUI if he or she drives while under the influence of intoxicating liquor, marijuana, or any drug, and is guilty of PC if he or she has actual physical control of a vehicle while under the influence of intoxicating liquor, marijuana, or any drug.
A DUI or PC offense is punishable as a gross misdemeanor. However, a DUI or PC offense becomes a felony offense if the defendant has three or more prior impaired driving offenses within the previous 10 years, or has previously been convicted of felony DUI or PC, or of Vehicular Homicide or Vehicular Assault while under the influence of intoxicating liquor or any drug. Prior impaired driving offenses include convictions of DUI, PC, Vehicular Homicide, and Vehicular Assault, as well as other impaired driving-related offenses and offenses involving impaired operation of commercial vehicles, vessels, aircraft, snowmobiles, and nonhighway vehicles.
Felony DUI is classified as a class B felony. Felony PC is classified as a class C felony. The statutory maximum sentence for a class B felony is 10 years in prison, a fine of $20,000, or both imprisonment and a fine; and for a class C felony is five years in prison, a fine of $10,000, or both imprisonment and a fine. The standard range sentence for a DUI or PC offense for a person with three prior impaired driving offenses is 13 to 17 months of incarceration, followed by one year of community custody.
Three or more prior impaired driving offenses within 15 years, rather than 10 years, elevates the classification of a DUI or PC offense from a gross misdemeanor to a felony.
