Oregon DUII Ignition Interlock Requirements (2026): Diversion, Conviction & Approved Providers
Oregon calls its offense DUII (Driving Under the Influence of Intoxicants) and requires an ignition interlock for virtually every DUII — both on diversion and on conviction. The removal standard is 90 consecutive days with no negative reports. Low-income drivers enrolled in SNAP may qualify for waived service fees through Oregon’s OHA-contracted vendor. A third DUII conviction results in permanent revocation.

Diversion vs. conviction — two different IID paths
Oregon offers a DUII diversion program as an alternative to conviction. The IID requirements differ depending on which path applies:
- Diversion: The court shall order an IID for the 1-year diversion period if your BAC was 0.08%+, you refused the test, or drugs were present. After 6 consecutive months with no negative reports and treatment compliance, you may move the court to vacate the diversion early under ORS 813.645. If diversion is successfully completed, the DUII charge is dismissed — no conviction record.
- Conviction: DMV imposes the IID requirement after your suspension ends. Duration: 1 year (1st conviction), 2 years (2nd), 2 years (3rd, but underlying revocation is permanent with a 10-year petition minimum).
If you are on diversion, your IID is ordered by the court and monitored through the court process. If you are convicted, the IID requirement is administered by Oregon DMV. The provider and device are the same; the administrative path differs.
The 90-consecutive-day clean window restarts on any negative report. Under ORS 813.635, the IID requirement ends only when a certificate shows no negative report for the last 90 consecutive days. A “negative report” is any tampering, unauthorized removal, lockout, or recorded test violation. If a negative report occurs on day 89 of a clean run, the 90-day clock restarts from zero. This is a rolling window — any violation during the final 90 days extends the requirement until a new 90-consecutive-day clean period is completed. Keep especially clean compliance throughout.
Indigence waiver: SNAP enrollment = waived service fees
Oregon’s OHA (Oregon Health Authority) contracts with one IID vendor to provide waived service-center fees for indigent customers. To access this benefit:
- Eligibility: Current SNAP enrollment (measured against federal SNAP income standards)
- Documentation: Current-month SNAP enrollment documentation, presented at each service visit
- Important: Only the OHA-contracted vendor provides this benefit — other vendors do not. Contact OSP or OHA to identify the current contracted vendor before choosing a provider if cost relief is needed.
OSP-certified providers
Oregon State Police certifies both providers and individual installers. Three major national brands are on the current OSP list. Guardian, Dräger, and ALCOLOCK are not on the Oregon list. ADS also appears on the OSP list as an additional approved vendor.
| Provider | Monthly est. | Coverage | |
|---|---|---|---|
| Intoxalock | $60–100 | Statewide | 888-283-5899 |
| Smart Start | $70–100 | Statewide | 800-831-3299 |
| LifeSafer | $65–95 | Statewide | 800-634-3077 |
Confirm current OSP certification at oregon.gov/osp before signing. Guardian, Dräger, and ALCOLOCK are not on the Oregon list. If seeking the indigence waiver (SNAP-based), contact OSP or OHA first to identify the current OHA-contracted vendor — only that vendor provides the service fee waiver.

How to get installed — 5 steps
- Determine whether you are on diversion (court-ordered IID for the diversion period) or convicted (DMV-administered IID after suspension ends). The administrative path differs; your provider and device are the same either way.
- If you may qualify for the indigence waiver (SNAP enrollment), contact OSP or OHA to identify the current OHA-contracted vendor before choosing a provider. Only that vendor provides the service fee waiver.
- Contact an OSP-certified provider, confirm current certification, and schedule installation. Bring your diversion or DMV paperwork to the appointment.
- Drive with a clean record. The removal standard is 90 consecutive days with no negative reports — any tampering, lockout, or test violation restarts the 90-day clock. For diversion, 6 consecutive clean months allows a motion to vacate early.
- When your 90-consecutive-day clean certificate is issued by the provider, DMV terminates the IID requirement. For diversion, bring the certificate to the court to move for early vacation of the diversion after 6 clean months.
90 clean days ends the requirement. Start your IID and keep your record clean — call to book now.
Book installation
Oregon calls it a “future responsibility filing” — functionally the same as SR-22. 3 years from the date of filing; triggered by DUII conviction, driving uninsured, certain traffic crimes, or any hardship permit application. See Oregon future responsibility filing costs and cheapest carriers →
Oregon DUII interlock FAQ
What is the difference between DUII diversion and conviction in Oregon?
Diversion is a court-supervised program where, if you complete the 1-year diversion period with the IID, treatment, and other conditions, the DUII charge is dismissed — no conviction. If you are on diversion and complete 6 consecutive months with no negative IID reports plus treatment compliance, you may move the court to vacate the diversion early under ORS 813.645. Conviction results in a criminal record and triggers the DMV-administered IID requirement after your suspension ends.
How does the 90-day removal requirement work in Oregon?
Under ORS 813.635, the IID requirement ends only when a certificate shows no negative report for the last 90 consecutive days. A negative report is any tampering, unauthorized removal, lockout, or recorded test violation. If a violation occurs on day 89 of your clean run, the 90-day clock resets from zero. This is a rolling window — any violation extends the requirement until 90 consecutive clean days are completed from the most recent negative report.
How do I qualify for the indigence waiver in Oregon?
Oregon’s OHA contracts with one IID vendor to waive service-center fees for SNAP-enrolled customers. You must show current-month SNAP enrollment documentation at each service visit. Only the OHA-contracted vendor provides this benefit — other providers don’t offer it. Contact OSP or OHA before choosing a provider to identify the current contracted vendor.
What happens after a third DUII conviction in Oregon?
A third DUII conviction results in permanent license revocation under ORS 809.235. You may petition the court no sooner than 10 years after the revocation. If reinstated, a 2-year IID requirement applies after any suspension ends. There is no hardship permit available for 2nd or subsequent convictions in Oregon.
Which providers are OSP-certified in Oregon?
Three major national providers are on the current OSP list: Intoxalock, Smart Start, and LifeSafer. Guardian, Dräger, and ALCOLOCK are not on the Oregon list. ADS also appears on the OSP list as an additional approved vendor. Verify current certification at oregon.gov/osp before signing, and contact OSP or OHA first if seeking the indigence (SNAP) waiver to identify the OHA-contracted vendor.
