DUI in Oregon
State-specific overview · Criminal Law
Oregon's DUI threshold matches the federal standard, but the state aggressively pursues impairment-based charges and requires ignition interlock devices for most convictions.
How Oregon treats DUI
Oregon prohibits driving with a BAC of 0.08% or higher, but officers can charge drivers with lower BACs if impairment is demonstrated through field sobriety tests or other evidence. All DUI convictions in Oregon require installation of an ignition interlock device on the vehicle, even for first offenses in many cases. The state also recognizes a separate offense for driving with a BAC of 0.04% or higher for commercial drivers. Oregon's implied consent law means refusal to submit to testing results in automatic license suspension and can be used as evidence of guilt in court.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
