Ignition Interlock Failure vs Violation: When a Failed Test Becomes a Problem

interlock failure vs violation

Summary: Understanding the difference between interlock failure vs violation will help you complete your Colorado interlock program successfully. A failure happens when your device detects alcohol and prevents your car from starting, often from mouthwash or hand sanitizer, while a violation is a reportable pattern of non-compliance that can extend your program or result in penalties. At Pit Stop Interlock, we provide the education, support, and reliable Smart Start technology you need to avoid violations and regain your full driving privileges.

What Is an Interlock Failure?

An interlock failure happens when you provide a breath sample that registers alcohol, and your device prevents your vehicle from starting. When this happens, your interlock device is doing exactly what it’s designed to do: keeping you and others safe. Interlock devices are sensitive and can detect alcohol from various sources, not just drinking. Interlocks can be triggered by alcohol-based mouthwash, certain medications, hand sanitizer residue, or even foods prepared with alcohol. If you fail a test, your device records the event, but it doesn’t automatically mean you’re in trouble.

Think of a failure as a data point. Your interlock system is collecting information throughout your program period, and occasional failures can happen for legitimate reasons. You’ll be given another opportunity to provide a clean sample after a short waiting period, usually a few minutes. If you genuinely haven’t been drinking, that second test will likely pass once any residual alcohol from external sources has dissipated. Know that a single failed test isn’t necessarily going to derail your entire program.

What Is an Interlock Violation?

A violation differs from a failure because it reflects a pattern of breaking the rules of your interlock program. Violations get reported, and they can result in serious consequences including lockouts, program extensions, additional fines, or criminal charges. Common violations include multiple failed tests in a short period, attempting to tamper, missing calibration appointments, or failing to provide a rolling retest. Each of these actions suggests either an attempt to circumvent the system or a failure to comply with the program.

Your interlock program has specific thresholds that determine when a failure becomes a violation. For example, if you have several failed tests in a row without passing tests in between, that pattern might trigger a violation report. Similarly, if you fail a rolling retest while driving, it’s even more serious than a failed startup test. A failed rolling retest implies that you are drinking and driving.

Interlock Failure vs Violation

The main difference between an interlock failure vs violation comes down to frequency, context, and intent. A failure is an isolated event. Your device detected alcohol and prevented the vehicle from starting. A violation is a reportable incident that suggests non-compliance with your program requirements. You can have failures without violations, but violations often involve multiple failures or other problematic behaviors.

Your monitoring authority understands that life happens and that not every failed test means you’ve been drinking and driving. They’re looking for repeated patterns that indicate you’re attempting to drive under the influence.

What Happens When You Have a Violation

Your interlock program has a set end date, but violations can push it further into the future. Each violation can add weeks or months to your program, which means more time with the device in your vehicle and more monthly fees. When a violation occurs, your interlock provider must report it to the Colorado DMV and your monitoring authority, which may be the court, probation office, or DMV, depending on your specific case.

The consequences depend on the type and severity of the violation, as well as your overall compliance history. For minor violations, you might receive a warning or be required to attend additional education or counseling. More serious violations can result in an extended program, additional fines, or, in severe cases, revocation of your interlock-restricted license. Also know that if you’re caught drinking and driving, you could face new criminal charges.

Interlock Failure vs Violations: Tips to Complete Your Program Successfully

The best way to avoid violations is to treat your interlock program seriously and follow all requirements consistently:

  • Always provide breath samples when your device prompts you.
  • Never ask someone else to blow into your device.Can mouthwash cause me to fail an interlock test?
  • Avoid alcohol completely during your program period.
  • Be mindful of products that contain alcohol and can cause false positives.
  • Keep your monthly calibration appointments on schedule. If you need to reschedule, do it before your appointment date passes, not after.

If you do fail a test, don’t panic. Wait a few minutes, rinse your mouth with water, and test again. Document any medications you’re taking, just in case you need to explain a failed test. If you continue to have problems, contact us immediately. We can help you troubleshoot and determine whether there’s a problem with your device or something in your routine causing false positives.

Frequently Asked Questions

Can mouthwash cause me to fail an interlock test?
Yes, mouthwash is one of the most common causes of failed interlock tests because many brands contain 20% alcohol or more. To avoid a failed test, wait at least 15 minutes after using mouthwash before providing a breath sample, or switch to alcohol-free alternatives. Rinsing your mouth with water before testing can also help clear any residual alcohol.
How many failed interlock tests result in a violation in Colorado?
A single failed interlock test typically won’t result in a violation if you provide a passing sample shortly after. However, multiple failed tests within a short period without passing tests in between, or a pattern of failures over time, will likely trigger a violation report to the Colorado DMV. The specific thresholds vary by monitoring authority. You should reach out to Pit Stop Interlock if you want to learn exactly what your program requires.
What happens if I miss my monthly interlock calibration appointment?
Missing your monthly calibration appointment can result in a violation being reported to the Colorado DMV, and your device may enter a lockout period where it won’t allow your vehicle to start. You should reschedule immediately if you realize you’ll miss your appointment, ideally before the due date passes. At Pit Stop Interlock, we make it easy. We offer convenient walk-in calibrations with quick 10-15 minute service times to help you stay on schedule.
