Not necessarily. First-time DUIs are misdemeanors in Oregon. A DUI becomes a felony if the new offense occurs within 10 years of at least two prior DUI convictions.
This was a change to the law, established by Ballot Measure 73 in 2010. Previously a DUI became a felony only if it the current incident occurred within 10 years of three prior DUI convictions. Additionally, any subsequent DUI (beyond #3) is a felony. It is also important to remember that the law now requires 90 days of jail. This 90 days may not be reduced for any reason (including good time/work time). If a person is convicted of Felony DUI under 813.010(5) for having three DUI convictions within the last 10 years, the person will be considered a Level 6 under the Sentencing Guidelines established by the Oregon Criminal Justice Commission.
