SR-22 requirement
An SR-22 is a certificate an insurer files with the state to confirm that a driver carries the liability coverage the state requires. Some states use an FR-44 or a different form for alcohol-related offenses; where Oregon does, the sources below say so.
| SR-22 filing required after a DUI | Yes |
|---|---|
| Filing period | 3 years |
SR-22. The Oregon DMV SR-22 Information page lists a DUII conviction among the events for which Oregon law requires an SR-22 filing. ORS 806.075(2) requires a person convicted of DUII to maintain future responsibility filings for three years from the date the first filing is required, at the higher coverage limits in ORS 806.075(1) ($50,000/$100,000/$10,000). DMV Form 735-6826 states the SR-22 must be on file 'for three years after the initial filing requirement.'

Exemptions and special cases
Four questions readers ask once an interlock is ordered — motorcycles, employer vehicles, medical inability to give a breath sample, and reduced-cost programs — answered as Oregon's interlock program page or statute states them.
| Question | Oregon rule |
|---|---|
| Motorcycles | Not addressed on the official pages read ORS 813.602 requires the device 'in any vehicle operated by the person' and, together with the Oregon State Police IID Program page and the Oregon DMV suspensions page, does not address motorcycles specifically (no statement that a device may or may not be installed on one or that riding one is permitted). The OSP program rules' definition of 'vehicle' (OAR 257-100-0005(34)) states that under ORS 801.365 and 801.133 motorcycles and autocycles are considered vehicles; that entry is recorded under 'other'. |
| Employer-owned vehicle | Exempt with conditions ORS 813.606: a person required in the course and scope of employment to operate a motor vehicle owned by the employer may operate it without a device if (1) the employer has been notified that the employee is driving on a hardship permit restricted under ORS 813.604, on a fully reinstated license within the first year after a first-conviction suspension, on a fully reinstated license within the second year after a second or subsequent conviction, or under a diversion-agreement IID condition, and (2) the employee carries proof of the notification and, if applicable, the fully reinstated license while operating the employer's vehicle in the course of employment. Oregon DMV Form 735-6874 (Employer Ignition Interlock Device Exception, rev. 5-25) is the employer-signed notice; it states the employee must carry the signed copy plus a valid license or hardship permit, that a self-employed person is not eligible, and that the employer notifies DMV when a hardship-permit holder stops driving company vehicles. What the source says“the person may operate that vehicle without installation of an ignition interlock device if: (1) The employer has been notified: (a) That the employee is operating with a hardship permit restricted as provided in ORS 813.604;” |
| Unable to provide a breath sample | Available ORS 813.602(4) directs DMV to adopt rules permitting medical exemptions. Under OAR 735-070-0082 a person qualifies if DMV finds that, due to a medical condition or impairment, the person is unable to operate an IID or unable to safely operate a vehicle equipped with one (e.g., cannot provide the necessary alveolar/deep-lung air sample, or consistently has breath ketone levels producing false positives over .020). The person and the primary care provider or treating physician/health care provider complete DMV Form 735-6941 (IID Medical Exemption); DMV may require more information or an IID provider's statement that the device cannot be adjusted; temporary exemptions expire on the stated date or six months after issuance; the person must carry DMV's exemption letter when driving. For a diversion-agreement IID, the exemption is requested from the court (ORS 813.602(3)(c)), and a court exemption is not valid for a conviction-based requirement. What the source says“(a) The person has a medical condition or functional impairment that does not allow the person to provide the necessary alveolar air or deep lung air sample to properly operate the device; or” |
| Reduced-cost / indigent program | Available — Indigent Ignition Interlock Device Program (Oregon Health Authority) / ORS 813.603 cost waiver ORS 813.603 allows the Department of State Police to waive, in whole or in part, or defer the person's responsibility for the reasonable costs of leasing, installing and maintaining the device for persons meeting indigence criteria that must be consistent with federal SNAP standards; waived costs are paid from the Intoxicated Driver Program Fund. The Oregon Health Authority's Indigent Ignition Interlock Device Program, in partnership with the IID Oversight Program, pays installation, monitoring and removal costs for Oregon residents who are required by an Oregon court to install an IID as the result of a DUII and are enrolled in SNAP benefits; no application is required, the installation is scheduled through the OHA-authorized vendor named on the OHA page, and proof of SNAP enrollment is shown at the installation appointment. The OSP page states costs may be waived or deferred for persons currently enrolled in SNAP, and the DMV page refers SNAP-enrolled residents to OHA. What the source says“The Oregon Health Authority partners with the Ignition Interlock Device Oversight Program to pay for costs associated with installation, monitoring, and removal of ignition interlock devices (IID) for low-income Oregonians.” |
| Statutory indigence criteria tied to SNAP (ORS 813.603(3)) | OSP's rules for waiving or deferring device costs must use indigence criteria consistent with federal SNAP standards. What the source says“The criteria must be consistent with the standards for indigence adopted by the federal government for purposes of the Supplemental Nutrition Assistance Program.” |
| DMV must adopt medical-exemption rules (ORS 813.602(4)) | Statutory basis for OAR 735-070-0082. What the source says“(4) The department shall adopt rules permitting medical exemptions from the requirements of installation and use of an ignition interlock device under this section.” |
| Diversion cases: medical exemption from the court (ORS 813.602(3)(c)) | A court may exempt a diversion participant who meets DMV's medical-exemption rules; the person must carry proof of the exemption while operating any vehicle. What the source says“A court may exempt a person from the condition in a diversion agreement to have installed and be using an ignition interlock device if the court determines that the person meets the requirements for a medical exemption in accordance with rules adopted by the department under this section.” |
| Bicycle DUII convictions excluded (ORS 813.602(6)) | The interlock section does not apply to a DUII committed while riding a bicycle (electric assisted bicycles are not bicycles for this purpose). What the source says“The provisions of this section do not apply to convictions of driving while under the influence of intoxicants if the offense was committed while the person was riding a bicycle.” |
| Motorcycles and autocycles are 'vehicles' under the OSP IID program rules (OAR 257-100-0005(34)) | The OSP rule definitions for the IID program define 'vehicle' broadly and note that motorcycles and autocycles are considered vehicles under ORS 801.365 and 801.133. What the source says“Under ORS 801.365 and ORS 801.133, motorcycles and autocycles are considered vehicles.” |
| Self-employed persons not eligible for the employer exception (DMV Form 735-6874) | The DMV employer-exception form states the self-employment limitation and the carry requirement. What the source says“NOTE: A person who is self-employed is NOT eligible for an Employer IID Exception.” |

Frequently asked questions
- Is an ignition interlock required after a first DUII conviction in Oregon?
- Yes. Under ORS 813.602(1), when a person is convicted of DUII under ORS 813.010 or a municipal ordinance, the Department of Transportation shall require an approved ignition interlock device in any vehicle the person operates, both before the person is eligible for a hardship permit and, for a first conviction, for one year after the ending date of the suspension or revocation caused by the conviction.
- How long does a repeat DUII offender need an ignition interlock in Oregon?
- ORS 813.602(1)(c) requires the device for two years after the ending date of the suspension or revocation for a second or subsequent conviction. Under ORS 813.602(2), a DUII conviction combined with certain homicide or assault convictions in the same episode, or aggravated vehicular homicide, carries a five-year requirement after the longest-running suspension or revocation ends.
- How does the Oregon interlock requirement end?
- Under ORS 813.635(1), the requirement continues until the person submits to DMV a certificate from the manufacturer's representative stating the device recorded no negative report for the last 90 consecutive days of the required period. If there is a negative report in that window, § 813.635(2) extends the requirement until a 90-consecutive-day clean certificate is submitted. Oregon DMV describes this as the 90-day No Negative Report.
- Is an SR-22 required after a DUII in Oregon, and for how long?
- Yes. The Oregon DMV SR-22 Information page lists conviction for driving under the influence of intoxicants among the reasons Oregon law requires an SR-22 filing. ORS 806.075(2) requires a person convicted of DUII to maintain future responsibility filings for a period of three years from the date the first filing is required, at the coverage amounts in ORS 806.075(1).
- What does Oregon DMV charge to reinstate after a DUII suspension?
- The Oregon DMV hardship permit page lists a reinstatement fee of $85 and a non-refundable hardship permit application fee of $75. DMV Form 735-6826 lists the reinstatement fee, an SR-22 on file for three years, an approved IID for one year (first conviction) or two years (second or subsequent), and a DUII treatment completion certificate as base-license reinstatement requirements.
