Traveling with an Ignition Interlock Device
When traveling, having an ignition interlock device (IID) or car breathalyzer, in your vehicle can feel like an added layer of complexity. Whether you’re going to work, visiting family, or taking a much-needed vacation, careful planning and staying compliant with IID regulations are essential.

Researching State Regulations
Ignition interlock requirements can vary significantly across states, which is why understanding the regulations of the states you’ll travel through is important. Regulations often address calibration requirements, reporting obligations, reciprocity agreements between states, and which authorities to notify when traveling.
Key Regulations to Research:
- Out-of-state Calibration: Some states allow you to have your car breathalyzer calibrated at your IID provider’s service centers outside your home state, while others require you to return for servicing. Check with your IID provider to confirm your options.
- Documentation Requirements: Ensure you have all the necessary paperwork, such as proof of IID installation and compliance with your home state’s IID program.
- Reciprocity Agreements: Many states have reciprocity agreements, meaning they share information about IID program compliance. This means your IID restrictions will follow you, regardless of where you travel.
- Notifying Relevant Parties: Before traveling, notify the appropriate state agencies or monitoring authorities. This step is not only required in some states but also ensures you remain compliant with your IID program.
To avoid surprises, always reach out to your IID provider or official state DMV resources for accurate and up-to-date information.
Staying Compliant on the Road
Traveling doesn’t change the fundamental rules of driving with an IID. Compliance remains key, regardless of your location.
Tips for Staying on Track
Follow All IID Procedures:
- Perform breath tests before starting the vehicle.
- Complete random retests as prompted by the device.
Avoid Alcohol:
- Do not consume alcohol before or while driving. Even trace amounts can be registered during a test.
Do Not Tamper with the Device:
- Any attempt to bypass the interlock device or circumvent its functions can lead to severe penalties and immediate program violations.
Compliance not only keeps you on the right side of the law but also ensures the safety of everyone on the road.
