What to Do When Your Ignition Interlock Device Records a False Positive

Steps to Take If You Encounter a False Positive

An ignition interlock device (IID) is often required for individuals convicted of DUI (Driving Under the Influence). This device helps prevent drunk driving. However, sometimes, IIDs can register false positives. This means they may indicate alcohol consumption even when none has occurred. Here’s what you need to know. Additionally, here are the steps to take if your IID records a false positive:

Understanding False Positives

A false positive occurs when an IID detects alcohol on the breath of the driver, triggering a lockout despite the driver being sober. Several factors can contribute to false positives, including:

 

• • Residual Mouth Alcohol: Certain mouthwashes, medications, or even certain foods can leave traces of alcohol in the mouth, which the device may detect.

• • Environmental Factors: Products like cleaning agents or adhesives containing alcohol can emit fumes that the IID may detect.

• • Device Malfunction: Although rare, technical issues or calibration errors in the IID can lead to inaccurate readings.

Steps to Take If You Encounter a False Positive

 

1. 1. Stay Calm and Cooperate: If your IID shows a positive reading and locks you out, stay calm. Follow the device’s instructions carefully, and cooperate fully to avoid further complications.

      Document the Incident: Keep detailed records of what happened. Note any recent use of mouthwash or exposure to alcohol-based products. These could influence the device’s reading.

      Request a Retest: Most IIDs allow for retesting after a short wait. Follow the device’s protocol for retesting to show that subsequent tests indicate no alcohol consumption.

      Contact Your Monitoring Authority: If the false positive continues or you face repeated issues, contact your monitoring authority immediately. This could be your probation officer, the DMV, or the company that installed the IID. Inform them of the situation and ask for guidance on how to proceed.

1. 1. Seek Professional Assistance: If you believe the false positive was due to a technical issue with the IID, contact the service provider who installed the device. They can perform diagnostics, recalibration, or repairs as necessary to ensure accurate readings.

1. 1. Keep Records and Documentation: Maintain thorough documentation of all communications, tests, and interactions related to the false positive incident. This documentation may be helpful if you dispute any violations or seek adjustments to your monitoring requirements.

Tips to Avoid False Positives

Avoid Alcohol-Based Products: To reduce the risk of false positives, steer clear of mouthwashes, medications, and other products that contain alcohol.

Follow Device Maintenance Guidelines: Regularly maintain and calibrate your IID according to the manufacturer’s recommendations. This helps prevent technical issues.

Conclusion

Experiencing a false positive on your ignition interlock device can be frustrating. However, responding calmly and taking the proper steps to resolve the issue quickly is important. Document all incidents, cooperate with authorities, and seek professional assistance when necessary. This will help you manage false positives and maintain compliance with your DUI requirements.

If you face ongoing issues or need more clarification about handling false positives, consult your DUI attorney or monitoring authority. They can provide tailored advice to help you navigate this part of your DUI sentencing effectively.
