Ignition Interlock Device (IID) Installation Information

The Department of Motor Vehicles (“DMV”) controls the Ignition Interlock Device Program (“IIDP”). For persons arrested and/or convicted of an offense involving driving under the influence, driving privileges may be suspended for a designated period based on the arrest and/or conviction. Generally, by installing an IID device and participating in the DMV’s IID Program, the person can gain restricted driving privileges during this time of driving privilege suspension.

According to the DMV, prior to the installation of an IID device, a certified IID installation company must contact the Mandatory Actions Unit (“MAU”) of the DMV to determine the participant’s eligibility. If the MAU determines that the participant is ineligible, the participant may be asked to sign a DMV DL 925 form which will allow the MAU to disclose information regarding the participant’s ineligibility to the installer. This information could include another action on the participant’s driving record, documentation regarding a drinking driver program, or SR 22 insurance proof. The participant can also contact the MAU of the DMV at 916-657-6525 to speak to a technician directly who can provide more information on the ineligibility determination.

After the MAU has made an determination that the participant is eligible for installation of an IID, the installer must complete the DMV DL 920 form and either provide a copy to the DMV on behalf of the participant or provide a copy of the completed DL 920 form to the participant to provide to the DMV either in person at a local DMV field office or by mail to the MAU.
