The DUII Law in Oregon
In Oregon the offense is DUII, and the limit is 0.08.
Driving in Oregon is consent to a breath or blood test when an officer has cause to suspect DUII; the license case that follows a refusal or a failed test is run by the DMV, separately from the criminal case.
Who Makes DUII Arrests in Marion County
The Marion County Sheriff's Office and the agencies that report for Salem, Keizer, Woodburn, Silverton, Stayton, Aumsville and four more cities make the DUII arrests in Marion County.
The FBI's agency list also places these agencies in Marion County: the Marion County State Police (state police); the Marion County Liquor Commission (state agency); the Marion County State Police makes the arrests on the state highways.
Together, the seven agencies in Marion County with all twelve months of 2025 on file reported 8,301 arrests to the FBI that year, all offenses together; the FBI's count for Marion County does not break DUII out.
