Oregon 735-6941 Ignition Interlock Medical Exemption

Oregon drivers required to use an ignition interlock device (IID), by a court under a DUII diversion agreement or by DMV after a DUII conviction, can seek a medical exemption with this form. The provider treating the relevant condition explains why the person cannot operate an IID and whether the condition is permanent or temporary. The exemption takes effect only after the court or DMV approves it.

Who completes it

The driver completes Section 1; the health care provider giving specialized treatment for the condition completes and signs Section 2; the court or DMV completes Section 3 to approve or deny.

Submitting and payment

How to submit it
The provider sends it to the agency requiring the IID (the court for a diversion, DMV for a conviction) or gives it to the patient to submit, and keeps a copy for the records.

Good to know

  • Under OAR 735-070-0082, qualifying reasons include a condition preventing an adequate alveolar or deep lung air sample, or breath ketones consistently reading over .020% BAC without alcohol.
  • The back page explains what the device demands, which the provider attests to having read: about 1.2 liters of breath sustained for 5 to 7 seconds, blowing patterns, and random retests while driving.
  • For a temporary condition, the provider gives the date it is expected to end, and the agency can approve the exemption only until a set date.
  • An approved exemption lets the person drive without an IID with no alternative requirement; the driver must carry it with their license or permit at all times.

Frequently asked questions

Who can complete Section 2 of Oregon's IID medical exemption?

The physician or health care provider giving specialized treatment for the particular medical condition or functional impairment. Section 2 asks directly whether you are that provider, along with your specialty, license or certificate number, the conditions you treat and how they prevent IID use.

Does the IID exemption go to the court or to DMV?

It depends on who required the device. A court can require an IID for the length of a DUII Diversion Agreement, at least one year; DMV requires one after a DUII conviction, for one, two or five years or indefinitely. The form goes to that agency, which approves or denies it in Section 3.

What conditions qualify for an Oregon IID medical exemption?

The provider must conclude the person cannot operate an IID, or a vehicle equipped with one, because of the condition. Oregon's rule gives two examples: being unable to provide the alveolar or deep lung air sample the device needs, or consistently having breath ketones that read over .020% BAC without alcohol.
