DL 9 Form – The DL 9 Form (full title: Application for Certification of Ignition Interlock Device, DL 9 REV. 6/2022) is the official California DMV document that manufacturers and providers must complete to certify breath alcohol ignition interlock devices (BAIID or IID) for legal use in California vehicles.
This form is not for individual drivers seeking to install an ignition interlock device after a DUI. Drivers use separate forms like DL 920 (Verification of Installation) or DL 925 (Installation and Removal Request). The DL 9 is strictly for businesses applying for DMV certification so their devices can be installed and used to help DUI offenders regain restricted driving privileges.
What Is the DL 9 Form and Why Is It Required?
The DL 9 Form allows the California DMV to certify ignition interlock devices that meet state safety and performance standards. Only certified devices from approved manufacturers can be installed on vehicles for court-ordered or DMV-mandated IID programs.
Certification ensures devices prevent drunk driving by requiring a breath sample before the vehicle starts and during random retests. As of 2026, California’s Statewide Ignition Interlock Device Pilot Program remains active (extended through January 1, 2033), making certified IIDs essential for many DUI offenders.
Manufacturers must submit the DL 9 as part of the occupational licensing process for BAIID manufacturers through the DMV’s Vehicle Industry Services portal.
Who Needs to File the DL 9 Form?
Only the main office of an individual, partnership, or corporation that manufactures or provides ignition interlock devices needs to complete the DL 9 Form. This includes:
- Device manufacturers
- Providers seeking certification for specific models
The form requires certification under penalty of perjury and an indemnity agreement protecting the State of California and the DMV from liability related to device installation, service, repair, use, or removal.

Why DL 9 Certification Matters in California?
Only DMV-certified ignition interlock devices appear on the official IID list used by courts, DUI programs, and installers. Without DL 9 approval, a device cannot legally be used for California’s IID requirements, which apply to many first-time and repeat DUI offenders under Vehicle Code sections such as 23575.
Common Confusion: DL 9 vs. Driver Forms (DL 920, DL 925, etc.)
Many drivers search for “DL 9 Form ignition interlock” by mistake. Remember:
- DL 9 → Manufacturer certification only
- DL 920 → Verification of Installation (for drivers)
- DL 925 → Installation/Removal Request (for drivers)
- DL 4062 → IID Exemption Request
If you are a driver needing an IID, visit the DMV’s Ignition Interlock Device page or contact an approved installer for the correct forms.
