This restriction does not allow you to drive without a valid DL.
You must submit either a Verification of Installation Ignition Interlock (DL 920) or Exemption for Ignition Interlock Device (DL 4054B) form to DMV within 30 days from the date the Order of Installment of an Ignition Interlock Device (DL 4054A) form was mailed. These forms ensure that you and the installer agree to the terms of the IID restriction.
If you were convicted of a DUI (CVC §§23152 or 23153) or “wet reckless,” (CVC §23103.5) you may be eligible for an IID-restricted DL. In addition to any other specified restriction requirements, you must meet the following requirements:
- Clear all other outstanding suspensions/revocations on your driving record.
- Comply with a DUI program's requirements and have the program provider submit the appropriate Proof of Enrollment Certificate (DL 107) or Notice of Completion Certificate (DL 101) form to DMV (whichever applies to your case).
- Submit to DMV a California Insurance Proof Certificate (SR 22) form issued by your auto insurance company that establishes proof of financial responsibility.
- Install an IID on your vehicle and provide DMV with a DL 920.
- Pay all required fees.
All required forms and fees may be submitted to any local DMV office or mailed to:
NOTE: Call DMV at (916) 657-6525 for assistace to determine eligibility for obtaining a restricted DL.
Multiple DUI Violations
If you were convicted of a second or subsequent DUI violation and have completed at least one year of your DUI suspension/revocation, you may qualify for a restricted DL if you meet the restriction requirements.
Second and Third DUI Violations–Alcohol Only
In addition, you will need to meet the restriction requirements.
If your violation occurred on or after January 1, 2012, and you were convicted of a "wet reckless" as a substitute for a DUI conviction, you may opt to end your 1-year administrative per se (APS) suspension after 90 days.
Court-Ordered 10-Year Revocation
If your violation occurred on or after January 1, 2012, you have three or more separate DUI convictions, and are revoked for 10 years under CVC §23597, you may be eligible for early reinstatement of your driving privilege with an IID-restricted DL. To be eligible for early reinstatement, you must serve five years of the revocation period, have no alcohol or drug offenses during the revocation period, and must provide a DL 101 for an 18 or 30-month DUI program, and provide a DL 920.
Effective July 1, 2010, legislation requires DMV to conduct an IID pilot program. If you are a pilot program participant, refer to the Ignition Interlock Device (IID) Pilot Program (FFDL 44) Fast Facts brochure for additional information.
Certain violations require DMV to immediately suspend or revoke your driving privilege if you have an optional IID restriction (for example, an attempt to remove, tamper with, bypass, or failure to comply with any requirement for IID maintenance or calibration). DMV may restore the IID-restricted driving privilege upon receipt of a new DL 920.
