Oregon DUII 10-Day Deadline: What Happens If You Miss the DMV Hearing Window

After a DUII arrest in Oregon, the single most time-sensitive deadline is the 10-day window to request an administrative hearing to challenge the DMV's proposed license suspension. Miss it, and you lose the right to fight the suspension — no extensions, no do-overs, and an almost impossibly narrow exception process. Here's exactly how the deadline works and what your options are if it's already passed.

How to Count the 10 Days

Oregon follows ORCP 10A (Oregon Rules of Civil Procedure) for calculating the deadline:

1. Day 0 is your arrest date — it's excluded from the count.
2. Start counting from the next day. If you were arrested on Saturday, Day 1 is Sunday.
3. Day 10 is your deadline — your request must be received by the DMV Hearings Case Management Unit by 5:00 PM.
4. Weekend/holiday extension: If Day 10 falls on a Saturday, Sunday, or Oregon legal holiday (ORS 187.010 and 187.020), the deadline extends to 5:00 PM on the next business day.

For blood test cases, the 10-day clock starts from the date the DMV sends the notice of suspension (not the date you receive it), because breath test results are instant while blood results take time to process.

Example: Arrested Friday night, June 5. Day 1 is Saturday, June 6. Day 10 is Monday, June 15. If June 15 is a regular business day, your request must be in the DMV's hands by 5:00 PM that day.

Why This Deadline Matters So Much

Requesting the hearing does two things:

It preserves your right to challenge the suspension. At the hearing, an Administrative Law Judge reviews whether the officer had reasonable grounds, whether you were lawfully arrested, and whether the test was properly administered. If the DMV fails on any point, the suspension is rescinded entirely.

It can extend your driving privileges. Your temporary permit (the bottom of Form 735-0075) is valid for 30 days. If you request a hearing and the Office of Administrative Hearings can't schedule it within that 30-day window, the proposed suspension is typically withheld — meaning your driving privileges stay active until the hearing happens and a decision is issued.

If you don't request the hearing, the suspension automatically takes effect on Day 30 with no further review.

What Happens If You Miss It

The DMV issues a final order denying your untimely request. The administrative suspension proceeds as proposed:

• Breath test failure: 90-day suspension beginning on Day 30
• Test refusal: One-year suspension beginning on Day 30

You cannot appeal the denial of an untimely request through normal channels. The only remaining option is a Just Cause Petition.

The Just Cause Petition (ORS 813.440)

This is the exception, but the statutory grounds are extremely narrow. Under OAR 735-090-0000, you must prove that circumstances entirely beyond your reasonable control and beyond the ability of a reasonable person to foresee prevented you from filing on time.

The DMV recognizes only three categories:

• Verified physical incapacity — you were physically unable to act, backed by a signed physician's statement
• Death in your immediate family during the 10-day window
• Documented DMV or OAH error — the agency itself caused the failure (e.g., incorrect address on the notice)

What does not qualify:

• Being out of town
• Waiting to consult with an attorney
• Not understanding the deadline
• Confusion about the difference between the DMV hearing and the court case
• Being busy dealing with other consequences of the arrest

If your Just Cause Petition is denied, there is no further administrative remedy on that front.

The Separate Court Timeline Still Runs

Missing the DMV hearing deadline does not affect your criminal court case. You still attend your arraignment (typically around Day 30), and you can still enter the DUII Diversion Program if eligible. But here's the critical distinction: completing diversion dismisses the criminal charge. It does not reverse or modify the administrative suspension you lost the ability to challenge.

This means a missed deadline locks in the DMV suspension regardless of how the court case resolves. If you failed a breath test and missed the hearing window, you serve a 90-day suspension even if diversion eventually dismisses the criminal charge. If you refused, it's a full year.

The Oregon First-Offense DUI Guide maps both timelines side by side — the criminal track and the DMV administrative track — with deadlines, forms, and the exact sequence for each.

Frequently Asked Questions

Does the 10-day deadline include weekends?

Yes, but with a safety valve. Calendar days are counted (including weekends), so the window is shorter than many expect. However, if Day 10 lands on a Saturday, Sunday, or state holiday, the deadline extends to 5:00 PM on the next business day.

Can my attorney request the hearing for me?

Yes. An attorney can submit the hearing request on your behalf within the 10-day window. However, public defenders are generally restricted from representing clients in administrative DMV hearings — they only handle the criminal court side. If you want attorney representation at the administrative hearing, you typically need private counsel specifically for that proceeding.

Is there a fee to request the hearing?

No. Requesting an Implied Consent hearing is free. The hearing itself is also free. This is one of the few steps in the DUII process that doesn't come with a price tag, which makes missing the deadline especially costly — you're giving up a free opportunity to challenge the suspension.
