Ignition Interlock Devices: The Basics of Leasing and Using Your Device

Ignition interlock devices (IID), sometimes referred to as breath alcohol ignition interlock devices, or BAIIDs, help prevent drunk driving. Often, DUI offenders are required to install an IID as a condition of regaining their driving privileges. 

Ignition interlock devices are small devices installed in your vehicle that require you to take a breath alcohol test before starting your vehicle. If you have alcohol in your system, you will not pass and will be unable to start your car until you do. The IID will also require retesting at various intervals, so you’ll be unable to beat the device by having a sober person test for you.

How to Get an Ignition Interlock Device

Whether you’ve been required to get an IID or are choosing to get one voluntarily, you should look for an approved provider you can trust. Intoxalock is one you can trust, and we meet state requirements everywhere our devices are available. Your state alcohol safety website or department of motor vehicles may also list other providers they work with to compare. 

When it’s time to get your device installed, here’s what you’ll do: 

• Make your installation appointment — our state specialists can help you find an Intoxalock location near you. They will get the details about your offense so they can get you to the right technician. Wherever you go, make sure the technician is certified in IID installation, so your device is installed correctly. 
• Go over how it works — your technician will go over how the device works with you. Make sure you understand and that it’s functioning correctly before driving off.
• Return for calibration — ignition interlock devices require frequent calibration, typically every 30-90 days. Choose a location that’s convenient for you, since you will be making many return visits.
• Get your certification of installation — many courts will require you to prove the IID was installed before you can obtain a hardship license or move forward with your court proceedings. Intoxalock provides a certificate of installation for this purpose. 
• Set up your account — Intoxalock state specialists can help you set up your device account online. Once this is done, you will be able to make payments online and manage your account there or via the app.

An important note: Generally, IIDs are leased, not purchased outright. Intoxalock devices cost between $2.50 and $3.50 per day, plus we offer a $10 monthly protection plan. 

If you notice any issues with your device, contact the installer right away. They can ensure your device is in good working order and keep you on track with court requirements. 

How to Use My Intoxalock Ignition Interlock Device

Ignition interlock devices are designed to prevent drunk driving. Once the device is installed, anyone who attempts to drive your car will need to pass a breath test before they can start. If you have any alcohol in your system, you will fail the breath test. 

Intoxalock devices were designed to be easy to use, so you can get back on the road quickly. Here’s what to do once your device is installed.

• Press the button — your handheld Intoxalock device only has one button on it, which makes things simple. Press it and wait for the LED display to show the word “blow”
• Take the breath test — Intoxalock uses a simple blow-inhale-blow pattern. Some other devices require a single long breath. Make sure you understand which method your device requires.
• View your results — if your BrAC is below the limit set by your state, the car will start. If it’s above the limit, your car will not start until you submit a breath sample that has no presence of alcohol. Sometimes innocuous things like mouthwash can cause failed re-tests, so be aware.
• Retest when necessary  — all states require mandated retests be submitted while the car is running. The device will beep to signal the retest request, and Intoxalock devices have a 6 minute delay to allow drivers to pull over to safety if need be. The blow-inhale-blow pattern is simple enough that many can retest while driving. If you fail the retest, you will be signalled to stop driving. Your car will NOT shut down, however.
