Minnesota’s ignition interlock program allows drivers convicted of a DWI to regain limited driving privileges sooner (if they install a breath-testing device in their vehicle), but the program comes with strict rules. Even minor violations can extend your time in the program, result in license revocation, or trigger new criminal charges.

If you’re enrolled in Minnesota’s ignition interlock program, here’s what you need to know about violations, early removal, and how to protect your driving privileges.

How the ignition interlock program works

Under Minn. Stat. § 171.306, the ignition interlock device (IID) prevents a vehicle from starting until the driver provides a breath sample showing no alcohol.

The program is available to:

  • First-time DWI offenders with a BAC of 0.16 or higher 
  • Repeat offenders 
  • Drivers whose licenses were revoked, suspended, or canceled for alcohol-related offenses 

It’s a pathway to restricted driving privileges while completing revocation periods.

Common ignition interlock violations

1. Tampering or circumventing the device

Any attempt to remove, disable, or bypass the ignition interlock is considered tampering. This includes:

  • Disconnecting the device 
  • Having another person blow into it 
  • Altering the wiring or power supply 

Tampering can result in:

  • Immediate license cancellation 
  • Extended program duration (up to 1 additional year) 
  • Criminal charges for interference with the device 

2. Failed breath tests

The device records all breath samples. A test failure occurs when:

  • A driver’s BAC is 0.02 or higher, or 
  • A “rolling retest” shows alcohol while driving 

Consequences:

  • First violation: Extension of the program period (often by 90 days or more) 
  • Repeated failures: Longer extensions or full program restart 
  • Possible criminal charges if driving privileges were contingent on sobriety 

3. Missed rolling retests

While driving, the IID requires random breath tests (rolling retests). Failing to take one or missing multiple tests can be treated as a violation—especially if there’s no valid explanation (such as a technical malfunction).

4. Early removal of the device

Removing the ignition interlock before completing the required period is a serious violation. Doing so may:

  • Cancel your driver’s license 
  • Reset your reinstatement process entirely 
  • Lead to reinstatement fees and longer program participation

You must receive official written authorization from the Minnesota Department of Public Safety (DPS) before removal.

5. Device lockouts or data issues

Lockouts occur when the device detects violations or repeated test failures. Missing scheduled calibration or data uploads can also result in a violation notice.

It’s critical to maintain regular communication with your device vendor and document any technical issues immediately.

How violations are handled

The ignition interlock program uses electronic monitoring, and reports are sent to the DPS. If a violation is detected, DPS may:

  • Send a written violation notice 
  • Extend your participation period 
  • Cancel your license (requiring full reinstatement) 

You can appeal violations or license actions through an administrative hearing, but deadlines are short—usually within 15 days of notice.

If you receive a violation notice, consult a Minneapolis criminal defense attorney right away.

How to avoid violations

  • Never allow anyone else to blow into the device 
  • Avoid using mouthwash, alcohol-based hand sanitizer, or vaping before driving 
  • Keep calibration and service appointments 
  • Report device issues immediately to your vendor and keep proof of communication 
  • Stay sober while in the program—any alcohol detection can lead to severe consequences 

Key takeaways

  • Minnesota’s ignition interlock program helps drivers regain limited driving privileges after DWI convictions. 
  • Violations include tampering, failed tests, missed retests, or early removal of the device. 
  • Even minor violations can extend your program or lead to license cancellation. 
  • You can appeal violations, but time limits are short. Legal guidance is essential.

Can someone else blow into my interlock for me?
