Understanding Your Ignition Interlock Device

An Ignition Interlock Device (IID) is a breathalyzer-type device installed in your vehicle. It's required by courts as a condition of driving after a DUI or DWI conviction. The IID prevents your car from starting if it detects alcohol in your breath. Understanding its operation is crucial for maintaining your driving privileges.

Initial Installation and Setup

What to Expect: The installation process usually takes about an hour. A certified technician will install the IID in your vehicle, typically near the steering column. They'll explain the device's operation and answer any questions.

Calibration and Testing: The technician will calibrate the IID and perform initial testing. This ensures the device is functioning correctly and recording accurate readings.

Important Documents: You’ll receive documentation outlining the device's usage, maintenance requirements, and contact information for support. Keep these documents readily accessible.

Daily Operation of Your IID

Starting Your Car: Before starting your vehicle, you'll need to provide a breath sample into the IID's mouthpiece. The device will analyze the sample for alcohol.

Random Testing: Throughout your driving session, the IID will randomly request additional breath tests. These are to ensure you remain alcohol-free while driving.

End-of-Trip Tests: When you turn off your vehicle, the IID will likely require another breath test. This is a final check to ensure you haven't consumed alcohol during your trip.

Maintaining Your IID

Regular Calibration: You'll need to schedule regular calibration appointments with the IID service provider. This ensures the device's accuracy and compliance. The frequency of these appointments will vary depending on the specific device and your jurisdiction.

Service and Maintenance: Follow the manufacturer's instructions regarding maintenance. This might include cleaning the mouthpiece regularly and avoiding exposure to extreme temperatures.

Reporting Issues: Report any malfunctions or difficulties with the device immediately to your service provider. Prompt attention can prevent potential violations.

Troubleshooting Common IID Issues

Failed Breath Test: If the IID fails a breath test, your vehicle will not start. This can be due to several reasons, including:

Alcohol Consumption: Ensure you haven't consumed any alcohol before attempting to start your car. Even mouthwash or certain medications can trigger a positive test.
Mouthwash or Other Substances: Avoid using mouthwash or other products containing alcohol before operating your vehicle. Inform your service provider of any medications you are taking.
Device Malfunction: If you suspect a device malfunction, contact your service provider immediately.

Device Malfunctions: If the IID isn't working correctly, it's crucial to contact your service provider promptly. They can diagnose the problem and arrange for necessary repairs.

Missed Calibration: Missing scheduled calibration appointments can lead to violations. Ensure you schedule and attend all required appointments.

Consequences of Non-Compliance

Failing to follow the rules and regulations regarding your IID can result in severe consequences. These can include:

License Suspension or Revocation: Your driving privileges could be suspended or revoked.
Jail Time: In some cases, non-compliance can result in jail time.
Fines: Significant fines could be imposed for violating the terms of your IID program.

Important Reminders

Always keep your IID service provider's contact information handy.
Be aware of the rules and regulations specific to your jurisdiction.
Never attempt to tamper with or bypass the device. This is illegal and will result in severe penalties.
Follow all instructions provided by your service provider.
Maintain regular contact with your probation officer or legal counsel.
