There are approximately 12,000 people in Illinois currently driving with a breath alcohol ignition interlock device (BAIID). These devices monitor former DUI offenders to prevent further episodes of drunk driving. To gain a clear understanding of this legal requirement, the following sections will explore several frequently asked questions about BAIIDs in Illinois.
What is a Breath Alcohol Ignition Interlock Device (BAIID)?
These devices are installed on a motor vehicle’s ignition system. In order to start the vehicle, the driver must register a test of their blood-alcohol concentration (BAC). If the BAIID fails to register a test — or registers a BAC of 0.025 or more — then the motor vehicle will not start.
After the initial test, the BAIID requires the driver to submit additional BAC tests at random times. If the driver fails to register or exceeds the established BAC limit, then the car will stop working properly.
