Ignition interlock devices are mandatory for drivers in Colorado who are convicted of more than one DUI offense, and they are sometimes used for first-time offenders as well. If your DUI attorney in Denver advises you that an ignition interlock advice is likely to be part of the resolution of your case, here are the answers to some of the questions you are likely to have.

What is an ignition interlock device?

Ignition interlock devices, or IIDs, are used to prevent drivers from operating a motor vehicle while intoxicated. The device consists of a Breathalyzer machine that you blow into to start the vehicle. If the device detects alcohol in your system, it will prevent the vehicle from being started. Typically, an IID will lock the ignition for a specific period before you can re-attempt the test. The period you are locked out gets longer every time you fail a Breathalyzer test. Many IIDs also require you to periodically take Breathalyzer tests while you are driving. The device will prompt you to do a test, and if you fail to do so or fail to test sober, an alarm may sound. The device may also record your failure to test or the results of a test that showed you were intoxicated.

Who is required to get an IID?

Under Colorado law, IIDs are mandatory after a second DUI conviction. In some cases, IIDs are required for drivers after their first DUIs, at the discretion of the court. Your DUI attorney will help you understand the nature of the charges and the exact penalties you could be facing. In some cases, you may be required to get an IID if you refuse to submit to a chemical test—blood, urine, or breath—at the time of your arrest.

Who pays for IID installation?

In most cases, the person convicted of the DUI is required to pay for the IID installation and maintenance. There may also be a security deposit required for the device itself. Your DUI attorney will tell you how to find an approved IID installer for your installation and any court-mandated maintenance.
