You Need an IID – What Now?


If you have received a DUI conviction you may be feeling overwhelmed with the steps you are required to take next. One of these steps may be the installation of an ignition interlock device or an IID. The ignition interlock device (IID) pilot program is designed to help you safely and responsibly return to driving. If you are notified you must participate in the ignition interlock device (IID) pilot program. Follow these steps:

  1. Call ALCOLOCK. As a licensed provider of IIDs, we can walk you through the process and answer any questions you may have about the device and installation. We are here to assist you through the entire process.
  2. You will need to book an appointment to have your IID installed. This can typically be done within 48 hours of your call. We aim to make the installation as time efficient as possible for you.
  3. Verify the installation with the California DMV. ALCOLOCK will provide a registered certificate to confirm that your approved IID has been installed. It is imperative you complete this step to ensure you can legally return to operating your vehicle.
  4. You will receive your IID-restricted license from the DMV allowing you to operate your vehicle.

Common Questions


Q: Which counties in California are participating in the IID Pilot Program?

A: If you are convicted of a DUI in Alameda, Los Angeles, Sacramento, and Tulare Counties you must participate in the IID Pilot Program. This applies even if you do not reside in these areas. For more details, visit the California Department of Motor Vehicles website.


Q: What happens if I don’t install an ignition interlock device (IID) after receiving a court order to do so?

A: You may have all driving privileges revoked if you do not provide verification (your registered certificate) that you have had an IID installed within 30 days of receiving your court orders. To avoid further delays to your license being reinstated, losing the possibility of a restricted license or further penalties call ALCOLOCK USA for a swift and easy installation process.


Q: How soon can ALCOLOCK install an IID in my vehicle?

A: Typically, the installation can be completed within 48 hours of calling ALCOLOCK.


Q: Who pays for the IID?

A: By law, the client is responsible for all fees associated with participating in the ignition interlock program. To ensure that this is accessible for as many clients as possible, reduced payment plans for lower income households are available. For more information on program subsidies, visit the California Department of Motor Vehicles website.


Q: How long is a typical IID program?

A: The law requires participation for a minimum of 5 months if you are convicted of DUI in one of the four counties participating in the IID Pilot Program.

** Note that violations increase the length of the time you are required to participate in the program.


Q: What is a program violation?

A: Program violations can be failing to provide a retest when required or trying to bypass the IID. You will receive a “Compliance Manual” when you enroll with ALCOLOCK that outlines all potential program violations. Be sure to read this carefully.


Q: How often are service appointments required?

A: In California, ALCOLOCK service appointments are required at least every 60 days. It is important to maintain these service appointments for the integrity of your IID.


Q: How long do the appointments take?

A: An ALCOLOCK service appointment typically take less than 20 minutes. Call and book your service appointment for a time that is convenient for you.


Q: Is the IID monitored?

A: California law mandates that every breath test is logged and encrypted by the IID. As a certified provider, ALCOLOCK is required to transfer this information to a secure database and report any violations to the DMV.


Q: How can I know if I will fail a breath test before taking one?

A: Besides avoiding alcohol if you plan to operate your vehicle, you can ensure that you don’t fail an IID breath test by testing yourself in advance. Advanced breath alcohol testers like the DRIVESAFE portable breathalyzer use the same sensors as IIDs.
