Calibration, Violations, and Staying Compliant

Calibration, Violations, and Staying Compliant

Author: Dan Rhodes

Introduction

By now you are used to living with your ignition interlock device in California. You know how to start your car, handle rolling retests, and avoid false positives. The next big step in your IID journey is understanding calibration and compliance. This part of the process can feel like DMV red tape, but it is really about keeping you on track and proving you are serious about finishing your program.

Calibration in California

California requires IID calibration every 60 days. Calibration is a short appointment where the device is checked, cleaned, and its data is downloaded and reviewed. Think of it like taking your IID to the Doctor for a quick check up. If everything looks good, you are back on the road in less than 30 minutes.

Miss a calibration, though, and things can get messy. The device may go into lockout mode, which means you may need a tow to the shop. Worse, missed calibrations can count as violations and can extend your IID term. 

Common IID Violations

Violations are every driver’s nightmare, but they are avoidable if you know what to expect. In California, the most common IID violations include:

– Failing a breath test (blowing over the limit).

– Missing or ignoring a rolling retest.

– Skipping a calibration appointment.

– Tampering with or trying to remove the device.

Every violation is reported to the DMV Mandatory Actions Unit and can trigger penalties like extra fees or a longer IID requirement.

Consequences of Violations

So what happens if you get a violation? Consequences vary depending on the situation, but they often include fines, an extended IID term, or even losing your restricted license altogether. Think of it like hitting the reset button on your progress. Every violation delays your finish line.

How Clear2Drive Keeps You Compliant

At Clear2Drive, we know compliance can feel like juggling fire. That is why we help you every step of the way:

– Automated reminders so you never miss a calibration.

Why Compliance Matters

Compliance is not about punishment. It is about proving to the state that you can handle the responsibility of driving again. Every calibration you attend on time and every clean test you blow gets you closer to removal day. Stay focused, stay consistent, and let Clear2Drive handle the reminders so you can handle the driving.
