Oregon DUII Case Timeline: How Long Does It Take?

The Short Answer

A first-offense DUII in Oregon takes at least the 12-month diversion period, plus the pre-entry court timeline and any court processing required after completion, if you go the diversion route. The criminal charge is dismissed after the 12-month diversion period, but administrative requirements (SR-22, IID compliance reporting, license reinstatement) extend beyond that. If your case goes to trial instead, the timeline is less predictable, with post-conviction requirements lasting two to three years.

Here's how it actually unfolds.

Days 0–10: The Emergency Window

The post-arrest process starts immediately. Two things happen simultaneously:

Day 0: The officer confiscates your license and issues the Implied Consent Combined Report. The bottom portion of this form is your 30-day temporary driving permit.

Days 1–10: For a breath-test failure or a breath, blood, or urine test refusal, you have exactly 10 calendar days to submit a DMV hearing request, calculated from the day after your arrest. For a blood-test failure, the 10-day period runs from the date DMV sends the suspension notice. Weekends count, but if the 10th day falls on a weekend or holiday, the deadline extends to the next business day. Miss this window and you waive the right to a hearing.

During this same period, you should retrieve your vehicle from impound (storage fees accumulate daily) and start identifying an attorney if you plan to hire one.

Days 10–30: Parallel Tracks Begin

Administrative track: If you filed a timely hearing request, the Office of Administrative Hearings schedules a telephonic hearing. Under ORS 813.410, the DMV must hold the hearing and issue a final administrative order within 30 days of your arrest. If OAH can't schedule it in time, the proposed suspension is typically stayed — you keep driving until the hearing happens.

Criminal track: Your arraignment is usually scheduled approximately 30 days after the arrest. This is your first court appearance, where the judge reads the charges, sets release conditions, and advises you about diversion eligibility.

Days 30–60: Diversion Entry

Day 30: Your temporary driving permit expires. If you did not request a hearing or the hearing upheld the suspension, the administrative suspension begins now. If OAH could not hold a timely hearing because of a scheduling constraint, the proposed suspension may be stayed or withheld.

Days 30–60: You have 30 days from your first court appearance to file the DUII Diversion Petition. This requires entering a conditional guilty or no-contest plea, which the court holds in abeyance. At the same time, you need to:

• Schedule your ADSS alcohol screening ($150) within 5–10 days of diversion entry
• Apply for a hardship permit once your mandatory waiting period expires if you need to drive during the suspension
• File an SR-22 with the DMV
• Install an IID in your vehicle

Months 2–6: Active Compliance

This is the grind phase. You're simultaneously managing:

• Treatment: Either DUII Education (12 hours over 4 weeks for low-risk assessments) or DUII Rehabilitation (12+ weeks of outpatient treatment for higher-risk assessments)
• Victim Impact Panel: A one-time, two-hour session ($25–$50)
• IID monitoring: Monthly calibration appointments and random rolling retests; a startup or random-retest reading at or above 0.021% BrAC can reset the compliance clock unless a subsequent test within 10 minutes is below 0.021% (with the camera confirming the same person for a startup test)
• Abstinence verification: Random urinalysis tests throughout the diversion period
• Hardship permit compliance: If you have one, driving only on approved routes during approved hours

If you installed the IID within the first five months and have six consecutive months of flawless compliance, plus completed mandated treatment or documented good standing with your provider, you become eligible for early IID removal under ORS 813.645.

Months 6–12: Completion and Dismissal

Month 6: Earliest possible IID removal (if eligible). Your attorney files a motion to vacate the IID requirement, supported by a certified "6-month no negative report" from your IID vendor and proof of treatment completion or documented good standing.

Month 12: The diversion period ends. The dismissal is not automatic unless local court rules provide an automatic process — you (or your attorney) must file a formal motion to dismiss with certificates proving treatment completion and IID compliance. The court reviews and enters the dismissal order.

Months 12–36+: Post-Dismissal Requirements

The criminal charge is dismissed, but your obligations aren't over:

• SR-22 insurance: Must be maintained for three full years from the date of reinstatement
• License reinstatement: Pay the $85 DMV reinstatement fee and confirm all clearances are processed
• Insurance premiums: Expect elevated rates (2×–5× your pre-DUII baseline) for three to five years

If Your Case Goes to Trial

Without diversion, the criminal timeline is less predictable. After arraignment, the case moves through pretrial conferences, potential motions and evidence challenges, and trial scheduling, with timing depending on the county's court calendar. Multnomah County generally moves faster; rural counties can be slower.

A conviction adds mandatory post-conviction requirements: 24 months of IID, the $1,000+ fine, 48 hours of jail or 80 hours of community service, and court-ordered treatment — all on top of the administrative suspension.

Track It All in One Place

The overlapping deadlines between the DMV and court tracks are where most people lose track of what's due when. Our Oregon First-Offense DUI Guide maps every milestone on both tracks into a single timeline, so you can see exactly where you are and what's coming next.
