The DUII Law in Oregon
Drunk driving is charged as DUII in Oregon, at a blood alcohol level of 0.08 or more.
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 Malheur County
The Malheur County Sheriff's Office and the agencies that report for Ontario and Nyssa make the DUII arrests in Malheur County.
The FBI's agency list also places these agencies in Malheur County: the Malheur County Liquor Commission (state agency); the Malheur County State Police (state police); the Malheur County State Police makes the arrests on the state highways.
