"What is an "Interlock?" An Ignition Interlock is a device that is installed on motor vehicles to prohibit individuals from operating a vehicle while under the influence of alcohol. It requires your breath sample before the engine will start and you are periodically required to provide breath samples while driving. If the device detects an elevated alcohol concentration level, the vehicle will not start.
You will be required to have an Ignition Interlock Device and make application for an Ignition Interlock Restricted License if you have been convicted of Driving under the Influence of Alcohol.
First DUI conviction with a BAC of .15 or above
Second or subsequent DUI conviction regardless of the BAC level
Circumventing or disconnecting the device will result in additional legal action, driving penalties and additional ignition interlock required time. Anyone assisting with device tampering and/or circumvention may also be subject to criminal and/or suspension action.

An ignition interlock restricted license shall not be issued to any person who is not eligible. An ignition interlock restricted license shall not be issued to any person holding a commercial driver's license (CDL).
