A DUI arrest in Colorado can have serious consequences—including the suspension of your driving privileges. However, Colorado offers a way for some drivers to regain limited driving rights through what’s called an Ignition Interlock License (IIL). This license allows you to legally drive with certain restrictions, primarily the requirement to install an Ignition Interlock Device (IID) in your vehicle.
If you’re trying to get back on the road legally after a DUI, here’s everything you need to know about qualifying for and obtaining a Colorado Ignition Interlock License—and why it’s crucial to consult with a Denver DUI lawyer throughout the process.
What Is an Ignition Interlock Device?
An Ignition Interlock Device is a breathalyzer installed in your car that prevents the engine from starting if it detects alcohol in your breath. In Colorado, the legal limit for IIDs is extremely low—typically 0.025% BAC. You may also be required to perform rolling retests while driving.
These devices are a key part of Colorado’s strategy to prevent repeat DUI offenses while allowing certain individuals the ability to drive for work, family, or essential needs.
Who Needs an Ignition Interlock License?
You may need to apply for an Ignition Interlock License if:
- You’ve been convicted of DUI (Driving Under the Influence) or DWAI (Driving While Ability Impaired)
- You’ve refused to take a chemical test under Colorado’s Express Consent Law
- You’re labeled a Persistent Drunk Driver (PDD)
- You want early reinstatement of your license after a suspension
The length of time you’ll be required to use an IID depends on the severity of your offense and your driving history.
Ignition Interlock Requirements Based on Offense
Here’s a general breakdown of IID requirements in Colorado:
- First-time DUI offense (BAC ≥ 0.08 but < 0.15)
Eligible for early reinstatement after 1 month of no driving with a minimum of 8 months on IID. - First-time DUI offense (BAC ≥ 0.15 or refusal to test)
Considered a Persistent Drunk Driver. Required to have IID for 2 years, with no early reinstatement. - Second or subsequent DUI offense
Typically requires 2 years with IID, and you may face longer waiting periods before eligibility.
Because each case has unique variables, it’s wise to have a Denver DUI lawyer evaluate your eligibility and guide you through the reinstatement process.
Steps to Get a Colorado Ignition Interlock License
1. Serve the Required Suspension Period
You must first serve the mandatory portion of your license suspension. For a first offense, this is typically 30 days. During this time, you are not permitted to drive at all.
2. Complete Alcohol Education or Therapy
If required, you must enroll in and show proof of participation in an alcohol education or therapy program, approved by the Colorado Department of Behavioral Health.
3. Get SR-22 Insurance
You must provide proof of SR-22 insurance, a special type of high-risk auto insurance required after a DUI. Your insurance company will file this certificate with the DMV on your behalf.
4. Have an IID Installed
Choose a state-approved IID provider to install the device in your vehicle. You will need to provide proof of installation to the DMV. Be aware that the cost of the device—including installation, monthly fees, and maintenance—must be paid out of pocket.
5. Apply for Reinstatement and Pay Fees
Submit your application for early reinstatement or a restricted license to the Colorado DMV, along with:
- Reinstatement fee (around $95)
- SR-22 form
- Proof of IID installation
- Proof of enrollment in alcohol education (if required)
Once approved, you will receive a restricted license that allows you to drive only vehicles equipped with an Ignition Interlock Device.
Conditions You Must Follow
While on an Ignition Interlock License, you must follow all program rules, including:
- Driving only vehicles with an IID
- Avoiding any alcohol use before driving
- Attending all required maintenance appointments
- Avoiding any attempts to tamper with or bypass the device
Violations can lead to an extension of your IID requirement or the revocation of your driving privileges altogether.
Why You Need a Denver DUI Lawyer
The rules around Ignition Interlock Licenses can be complex and change depending on your individual circumstances. A Denver DUI lawyer can help by:
- Reviewing your eligibility for early reinstatement
- Guiding you through paperwork and DMV requirements
- Representing you at DMV hearings, if necessary
- Advising you on how to remain in compliance with IID regulations
Mistakes in the process or missteps while using the device can cost you your limited license—so legal guidance is highly recommended.
