Statewide Ignition Interlock Device Pilot Program

Pursuant to state law, the Department of Motor Vehicles (DMV) will conduct a Statewide Ignition Interlock Device (IID) Pilot Program that requires all repeat and all injury-involved driving under the influence (DUI) offenders to install an IID for a time-period ranging from 1 to 4 years, depending on the number of prior DUI convictions.  Offenders who install an IID may drive anytime or anywhere, as long as the vehicle is equipped with an IID. 

The pilot program applies to DUI offenders convicted of a DUI involving alcohol or a combination of alcohol and drugs, and whose offenses occur between January 1, 2019 and January 1, 2026, except for the following offenders:

  • First-time offenders whose violation did not involve drugs only, and did not result in injury.
  • Repeat offenders whose violation involved drugs only.
  • Offenders who were administratively suspended after their DUI arrest.
  • Offenders approved for an IID exemption.

IID Restriction Requirements

Pilot program participants may immediately comply with the mandatory IID installation without serving any suspension or revocation period.  Before applying for an IID-restricted driver license, all offenders must meet the following requirements:

  • Clear all other outstanding suspensions or revocations on the driving record.
  • Install an IID on a vehicle the offender operates and provide DMV with a Verification of Installation Ignition Interlock form (DL 920).
  • Provide a Proof of Enrollment Certificate (DL 107) or Notice of Completion Certificate (DL 101) for the appropriate DUI program length.
  • Provide a California Insurance Proof Certificate (SR 22).
  • Pay all applicable reissue and restriction fees, including additional Administrative Service Fees.

Alcohol-Involved First-Time Offenders

Under the pilot program, first-time alcohol-related DUI offenders may have a court-ordered IID installation period of up to 6 months upon conviction.  In the absence of a court order, first time offenders may opt to apply for an IID restriction for up to 6 months, or may opt to apply for a restriction allowing them to drive to, from, and during the course of their employment and to and from their DUI program for one year. 

Drug-Only Repeat Offenders

Repeat offenders whose offense involved drugs only may qualify for an IID-restricted driver license after serving at least one year of their DUI suspension or revocation.

Administrative Per Se Offenders

Administrative Per Se (APS) offenders may opt to apply for an IID restriction for up to 4 months for a first-time non-refusal offense, and up to one year for a repeat non-refusal offense.  These offenders may avoid any suspension period by applying for the optional IID restriction immediately. 

Note: APS offenders who opted to apply for an IID restriction may receive credit towards the mandatory IID installation period required if convicted.  Only multiple and injury offenders have a mandatory IID restriction period. 

Exemption from Mandatory IID Installation

Offenders subject to mandatory IID installation under the pilot program may qualify for an exemption.  If an exemption is granted, offenders must serve their full suspension or revocation term and complete their DUI treatment program.


Customers with questions related to a DUI suspension or revocation should contact the Mandatory Actions Unit at (916) 657-6525.
