There are safeguards present to prevent false positives, false negatives, tampering, and another person from giving the breath alcohol sample. All ignition interlock systems keep a running log of activity so an accurate report can be delivred to your court appointed monitoring officers. Many of the new models take a digital photo of the breath alcohol sampling process to ensure that the person using the device is in fact the driver.


Ignition Interlock devices keep a record of the activity on the device and the interlocked vehicle’s electrical system. The state requires that you bring your vehicle back to the installation location every 30 days after the installation, so that the device is checked and a report is sent to the state. When you are ready to drive the vehicle, you will have to blow approximately 1.5 liters of air into a handheld alcohol sensor unit.

If your breath alcohol content is over a preset limit, the device will not allow the car to start. Rolling tests occur at random intervals, from about 5 minutes to 45 minutes after the car has started. These tests are designed to keep the driver from having a sober friend blow into the ignition interlock device. It also prevents the driver from drinking alcoholic beverages once the car has been started.

If the driver fails to provide a breath sample or had a BAC level over the preset amount during one of these rolling tests, the ignition interlock device will issue a warning and an alarm will go off. The alarm is the horn honking until the ignition is turned off. However, the ignition will not automatically shut down while the car is being driven.

The ignition interlock devices contain a computer chip that records your BAC content when you take the breath tests. If your BAC is over a certain limit, either when trying to start the car or during one of the rolling tests, this report can be downloaded and provided to the RMV. The reports will also note if the device has been tampered with.
