An ignition interlock is a breath analyzing device slightly larger than a cell phone and is wired to the vehicle’s ignition and installed on the vehicle dashboard. Before the vehicle can be started, the driver first must exhale into the device. If the interlock detects alcohol on the breath, the engine will not start.

At random times after the engine has been started, the device will require the driver to provide another breath sample. If the breath sample isn’t provided, or the sample exceeds a set blood alcohol level, the device will log the event, warn the driver and then start up an alarm (e.g., lights flashing) until the ignition is turned off, or a clean breath sample has been provided.

For safety reasons, the device can not turn off the car ignition once it has been started.
