Breath Alcohol Ignition Interlock Device (BAIID) FAQs

Many states require a BAIID following a drunk driving offense. There are many providers who can install state-approved interlock devices.

What is a BAIID?

A BAIID is a Breath Alcohol Ignition Interlock Device. These devices, like IIDs, measure breath alcohol content, BrAC. The devices are wired into a vehicle’s ignition system and require the driver to test their BrAC and pass before they are allowed to start their vehicle.

Who is Required to Install a BAIID?

It varies by state, but typically a BAIID is required after a DUI offense or substance-related moving violation. Often, BAIIDs are required in order for offenders to regain driving privileges.

What Does a BAIID Do?

When a BAIID is installed, the driver must blow into the device to test their BrAC. They must pass the test or they will be unable to start the vehicle. Throughout most trips, the BAIID will also request random retests. All test results are recorded and shared with the state’s monitoring authority. 

How Do BAIIDs Work?

The driver first starts the device and waits for the screen to say it is ready for testing. Then, the driver will blow into the device using the instructed breath pattern. If they pass, they will be able to start the vehicle. If they fail, the device will allow them to try again in a few minutes. If they fail repeatedly, they will be locked out of the device. During most trips, retests are requested at random intervals to ensure the driver stays sober.

What Is the Cost of BAIIDs?

Offenders are required to cover the cost of their own device. Prices vary depending on your state, vehicle make and model, and the interlock provider you choose. Typically, devices are between $100 and $150 to install and between $80 and $120 for a monthly lease. Some states offer financial assistance for qualified offenders. 

Where Can I Get a BAIID?

There are many vendors who can install your BAIID. First, you will want to check with your state to obtain their list of preferred vendors. Check with your attorney or DMV if you are unsure which providers are allowed. Once you decide, you can make your appointment through the interlock provider.

What Is a BAIID Violation?

BAIID violations could include test failures, attempts to tamper with the device, or not installing the device as instructed. In states with compliance-based interlock policies, violations may lead to further penalties including the interlock term getting lengthened.

Some minor violations include:

  • Three test failures within the first two months of the monitoring period
  • Missed calibration appointments (customers must have their device calibrated every 30-90 days depending on the state)

Major violations include:

  • Missing a random retest/not taking the random retest when prompted
  • Failing the random retest
  • Arrest for drunken or drugged driving
  • Attempting to tamper or circumvent the device
  • Three minor violations within one monitoring period
  • Unauthorized removal of the device
  • Driving a vehicle without a mandated BAIID

What Happens if I Have a BAIID Violation?

It varies by state, but in compliance-based states, the interlock term will be lengthened due to violations. Some states may go further and suspend or revoke the offender’s driver’s license. After multiple violations, some offenders may have their car impounded for 30 days or seized.

Am I Able to Appeal My BAIID Violation?

Check your state's appeals policy to determine if this is possible. It varies by state.

How Can I Remove My BAIID Device?

If your device was mandated, wait until you receive notification from the state that you are authorized to remove the device. When you have the authorization, you can make an appointment with your interlock provider to have the device removed. It is important to have the device removed by a professional, as they will do so without damaging your vehicle and also ensure the device is returned to the interlock provider.
