    What is the legal blood alcohol concentration (BAC) limit for adult drivers age 21 or older in Oregon?

    The answer

    Answer: A. Under Oregon law, it is illegal for an adult driver age 21 or older to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. You can also be convicted of DUII with a lower BAC if alcohol or drugs impair your driving ability. Conviction results in driver license suspension, heavy monetary fines, and mandatory installation of an ignition interlock device.
