What is an ignition interlock device and when is it required?
The ignition interlock device is an instrument which, when installed in an automobile, requires the driver to blow into the device before the engine will start. The device detects the presence of alcohol on the driver’s breath and will disable the vehicle’s engine in that event. The device is expensive and must be calibrated regularly. The Court can order the device be installed in any vehicle owned or operated by the defendant, for up to three years. It will be considered a possible condition of probation whenever a defendant has a prior conviction, or where a first offender’s breath or blood alcohol reading is over .20 percent. In addition, the DMV may require proof of installation of the device before granting a restricted license after a year of the suspension has elapsed.
