How the 2025 DWI Law Changes Affect License Reinstatement

All Minnesotans should be aware of a significant update to the state’s DWI laws that took effect on August 1, 2025. A new law passed during the 2025 legislative session significantly expands the use of ignition interlock devices and extends the lookback period for repeat DWI offenses. The changes affect how and when drivers with past offenses can regain their driving privileges.

This update reflects a shift in how Minnesota handles DWI-related license reinstatements, with expanded requirements that may affect many drivers across the state.

At Sieben Edmunds Miller, we help individuals navigate the complex legal and administrative consequences of DWI charges. Here’s what you need to know about these changes to Minnesota’s ignition interlock program:

New Minnesota DWI Law Expands Ignition Interlock Requirements as of August 1, 2025

What Is Changing Under the New DWI Law?

The new law makes the ignition interlock program mandatory for more drivers and imposes stricter requirements for those with multiple DWI offenses or criminal vehicular convictions. 

Mandatory Ignition Interlock for Repeat Offenders

As of August 1, 2025, any driver who has more than one DWI offense within the past 20 years must participate in the ignition interlock program in order to be eligible for a driver’s license. Previously, the lookback period for determining repeat offenses was only 10 years.

This means that even older offenses, dating back two decades, can now trigger a requirement to use an interlock device.

Expansion to Criminal Vehicular Homicide and Operation

Drivers convicted of criminal vehicular homicide (CVH) or criminal vehicular operation (CVO) involving alcohol are now required to complete the ignition interlock program before they can drive again. This change closes a prior gap in the law and imposes stricter oversight for the most serious driving-related crimes. 

Length of Program Participation

Under the updated law, the minimum duration for participating in the ignition interlock program depends on the driver’s offense history: 

  • 1 prior DWI offense within 20 years: 2 years of interlock use 
  • 2 prior offenses (lifetime): 6 years 
  • 3 or more priors: 10 years 
  • CVH/CVO involving death or serious injury: potentially 15 years or longer 

These terms must be satisfied before a driver is eligible for full license reinstatement.

Substance Use Treatment Requirement

All participants in the ignition interlock program must also complete a licensed substance use disorder treatment or rehabilitation program. This requirement reflects the law’s dual focus on accountability and recovery.

New Penalties for Noncompliance

Driving without a properly installed and functioning ignition interlock device while your license is revoked for a DWI-related offense will now be classified as a gross misdemeanor under the new law.

This offense carries serious consequences, including possible jail time, extended license revocation, and additional ignition interlock program requirements.

License Reinstatement Fee Change

Previously, individuals were required to pay the $680 license reinstatement fee before enrolling in the ignition interlock program. Under the new law, drivers can begin participating in the program before paying the fee, a change that may make it easier to get back on the road sooner. However, the full fee must still be paid before a standard license is reinstated. 

Why Was This Law Passed?

This legislative update followed heightened attention to the risks posed by repeat impaired driving incidents. Lawmakers sought to address gaps in the license reinstatement process and improve monitoring tools for individuals reentering the driving population after serious convictions. 

The reforms reflect an effort by Rep. Larry Kraft and Sen. Ron Latz to establish more consistent standards across offenses and ensure public safety through structured accountability measures like ignition interlock and treatment requirements.
