How to Stay Compliant with Colorado Ignition Interlock Laws
Learning everything you can about Colorado interlock laws and violations can help you save money and provide peace of mind through your DUI journey.
If you’re dealing with a DUI in Colorado, you know your ignition interlock device (IID) is your ticket to driving freedom while you prove you can make responsible choices. IID violations in Colorado are taken seriously by the DMV and can affect your ability to regain full driving privileges after a DUI.
Every failed test, missed retest, or missed service appointment for your device is logged and reported. If you rack up enough interlock violations, you could face longer restrictions, license suspension, or even criminal charges. That means more time off the road, more money out of your pocket, and more stress for you and your family.

Colorado DUI Interlock Laws and Violations
An ignition interlock violation happens when you don’t follow the rules of your ignition interlock device. An IID is the in-car breathalyzer required after most DUI convictions in Colorado and in most other states, too. It doesn’t matter if you’re in Denver or Colorado Springs; you will need to comply with Colorado DUI laws if you’re convicted of drunk driving. The ignition interlock violations Colorado residents face are typically tied to missed tests, alcohol detection, or tampering issues.
These violations can be frustrating but understanding them helps you stay on track and avoid bigger problems. For a full breakdown of the different types of ignition interlock violations, take a look at our complete list of common IIID violations and what they mean.
What is an IID Violation in Colorado?
An ignition interlock violation in Colorado happens when you break the rules set for your ignition interlock device, which is required after a DUI, some Driving While Ability is Impaired (DWAI) convictions, or certain license revocations.
4 Common Types of Ignition Interlock Violations
1. Failed Breath Test
Your interlock will prevent your car from starting and record a violation if it detects alcohol on your breath.
2. Missed or Failed Random Retest
While driving, the IID may ask for a random retest. If you miss or fail this test, it counts as a violation.
3. Tampering with the Device
This includes removing, altering, or trying to bypass the interlock device, or having someone else blow into the device for you. Tampering is a crime in Colorado and can lead to immediate license revocation and criminal charges.
4. Missed Maintenance or Calibration
Failing to bring your vehicle in for required check-ups can result in a violation.
Avoiding interlock violations and lockouts is totally in your control. Stick to the Colorado DMV interlock policy, keep up with maintenance, and ask for help when you need it, and you’ll stay ahead of penalties and get your full driving privileges back faster.

Steps to Take After an IID Violation in Colorado
A single mistake won't ruin your entire IID program, and taking the proper steps quickly can help protect your license and eligibility for early device removal.
- Review your violation notice: Carefully read communications from the DMV or your IID provider to understand your violation.
- Contact your IID provider: They can explain what triggered the violation. It could have been a failed BAC reading, missed calibration, or a tampering alert.
- Consult a DUI attorney: Your lawyer can help you understand your options and prepare for a hearing or appeal. Let them know if you believe the violation was in error so they can help you build a case.
- Request a DMV hearing, if applicable: You may have a short window to request one, but a hearing lets you present your side of the case and helps protect your license.
- Demonstrate you've resolved the issue: Schedule missed service appointments, renew a lapsed lease, or address challenges that caused the violation. Ensure the DMV receives confirmation of these and keep a copy of the documents.
- Work to avoid future violations: Learning what caused your violation can help you avoid another one.

Your Colorado Interlock Violation Questions Answered
What happens if you don't service your interlock on time?
The IID lockout rules Colorado enforces are strict: failing to meet service deadlines can immediately impact your ability to drive legally. If you miss a scheduled calibration or maintenance visit, your device may enter a lockout state. According to the rules for ignition interlock devices in Aurora and across Colorado, failure to service the device every 60 days can result in license suspension until compliance is restored.
Can you argue against a Colorado interlock violation or penalty?
If you believe an interlock violation was reported in error, you can request a hearing through the Colorado DMV. Under Colorado DUI interlock laws, you can present evidence and testimony to dispute the violation. A DUI attorney might help improve your chances of a favorable outcome.
How many interlock violations can you have in Colorado before facing penalties?
Typically, three or more violations within a 12-month period can trigger consequences like license suspension or an extension of your IID restriction. The Colorado DMV tracks these violations and applies penalties based on your compliance history. Your IID provider must report violations to the DMV.
