An ignition interlock device (IID) is a portable breathalyzer that is installed into your car. Before you can start your vehicle, you must pass the breathalyzer test each time. Because the ignition interlock device is wired to your ignition, once you pass the test, you are able to start the car. The court allows DUI offenders to obtain an ignition interlock device so that they can continue to drive.
As a result of a DUI arrest, you may be required to apply for an ignition interlock device, as well as an ignition interlock license (IIL). Generally, these devices are required prior to trial for repeat DUI defendants, as well as first-time defendants whose blood alcohol content registered above a certain range.

Important Tips for Using Your Ignition Interlock Device (IID)
Once your IID is installed, follow these essential tips to avoid issues and stay on the right side of the law:
- Absolutely No Drinking and Driving: Never attempt to drive after drinking.
- No Third-Party Use: Don’t allow anyone else to blow into your IID. This can lead to violations.
- Avoid “Testing” the Device: Don’t use the IID as a way to check anyone’s alcohol level. The results are logged and reported.
- Wait Before Driving After Certain Products: Some everyday items can cause false positives. To avoid issues, wait at least 15 minutes after using any of the following before attempting to start your vehicle:
- Mouthwash
- Spicy foods
- Soda
- Yeast-based foods (bread, donuts, cinnamon rolls)
- Alcohol-filled chocolates
- Breath mints
- Perfume or aftershave
- Hair spray
- Nyquil or similar products (Note: Nyquil contains alcohol—use caution.)
- Handling False Positives: If you receive a false positive, rinse your mouth with water and wait a few moments before trying again. Documenting the incident with a second test can help avoid misunderstandings. Talk with your attorney immediately about whether you should get an EtG urine test to establish you have not been drinking.
- Responding to IID Alerts: When the IID prompts for a breath sample while driving, respond promptly. Ignoring these prompts may lock you out of the system, requiring costly intervention to restore access.
- Avoid Missed IID Appointments: Attend all scheduled IID appointments to stay in compliance and avoid penalties.
- Seek Help for Device Issues: If you experience any problems with your IID, contact your provider immediately. They are there to help keep you on the road.
