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 Forest Grove
The Washington County Sheriff's Office and the agency that reports for Forest Grove (filed by the FBI as Forest Grove Police Department) make the DUII arrests in and around Forest Grove.
The FBI's agency list also places these agencies in Washington County: the Washington County Liquor Commission (state agency); the Hillsboro School District (other agency); the Washington County State Police (state police); the Washington County State Police makes the arrests on the state highways.
Together, the 12 agencies in Washington County with all twelve months of 2025 on file reported 18,060 arrests to the FBI that year, all offenses together; the FBI's count for Washington County does not break DUII out.
The Portland Police Department and the Lake Oswego Police Department are each listed by the FBI across several counties including Washington County, so their arrests are not broken out for Washington County here.
