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.

There are only five licensed and approved ignition interlock providers in Colorado. They are listed below:

Smart Start, Inc. 
Westminster, CO 80030

Guardian Interlock Systems 
Denver, CO 80022

Denver, CO 80216

LifeSafer of Colorado 
Aurora, CO 80011

Draeger Safety Diagnostics 
Denver, CO 80216

To determine if you will be required to have the ignition interlock device installed on all vehicles you own or may drive, visit the driver’s license reinstatement section of our site or contact the Colorado Department of Revenue, Division of Motor Vehicles (DMV) at 303.205.5631 for full reinstatement requirements.
