      What is a Breath Alcohol Ignition Interlock Device (BAIID)?

      A breath alcohol ignition interlock device, or BAIID, is a portable device that can test your breath alcohol content (BrAC). From there, the device estimates your blood alcohol content. In many cases, a BAIID is required to be installed following an alcohol-related driving offense.

      BAIIDs help with driver safety because, once installed, they ensure the following:

      • No drunk driving — BAIIDs require users to test their BrAC before they can start their car. If they have any alcohol in their system, they won’t be able to start their car.
      • No skipping a test — the devices also require retesting during every trip, so drivers cannot have a sober friend take the breath test for them.

      If the BAIID was required by the court following an offense, all failures are reported to the proper authority. Voluntary BAIIDs are available as well, for anyone who wants to use one as a sobriety aid or safety tool.

      Do I Need a BAIID for My Vehicle?

      There are many reasons to get a BAIID for your vehicle. If you’re unsure if you need one, check with your attorney or court official. In general, you need a BAIID if:

      • The court has required you install a BAIID following a DUI offense
      • The court or licensing body requires you install a BAIID to regain limited driving privileges
      • You’ve decided on your own to install a BAIID for safety reasons

      With the first two options, you will have criteria to follow and must install a BAIID from an approved provider. Your state will have a list of approved providers available, and they will know the criteria for your state. An Intoxalock state specialist can also help walk you through the process.

      Requiring a BAIID in Illinois

      If you have been arrested for a DUI in the state of Illinois, you may be required to install a BAIID in your vehicle. Depending on your offense, you may need to install a BAIID in order to obtain a Monitoring Device Driving Permit (MDDP), a Restricted Driving Permit (RDP), or as a requirement from a court order. For more information on Illinois BAIID laws, visit our Illinois state requirements page.

      As required by the Office of The Illinois Secretary of State, you will also have to submit a sample of your BrAC at random intervals while your vehicle is on, commonly referred to as a random retest. This random retest prevents you from operating your vehicle while intoxicated after you’ve already started your vehicle.
