Ignition Interlock Device Installation

Ignition Interlock Device Installation

Our DUI Lawyers in Denver Explain Your Options

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.

Colorado, like many other states, is requiring repeat offenders and excessive BAC first-time offenders to install the ignition interlock device in all vehicles they own in order to reinstate driving privileges. As of January 1, 2009, Colorado requires all offenders to install the ignition interlock device in their vehicles in order to obtain a restricted license.
