Minnesota’s New DWI Laws Are Tougher Than Ever

If you have a DWI on your record from the last decade — or you’re facing a new charge — Minnesota’s 2025 DWI law changes may affect you more than you realize.

Last year, Minnesota enacted changes to its DWI laws that significantly increase the consequences for drivers, especially those with prior offenses. The new laws went into effect on July 1, 2025.

If you are facing a DWI charge or have a prior offense on your record, understanding these new laws is critical. So is having an experienced defense attorney who knows how to navigate both the criminal and administrative sides of your case. At The Law Office of Lauren Campoli, we have extensive experience defending individuals against DWI charges and helping them protect their constitutional rights, driving privileges, and futures.

What You Need to Know

The Look-Back Period Has Doubled to 20 Years

One of the most impactful changes is the expansion of Minnesota’s DWI look-back period from 10 years to 20 years. This means prior DWI-related incidents from up to two decades ago can now be used to:

  • Increase license revocation periods
  • Trigger enhanced ignition interlock requirements
  • Require completion of chemical dependency treatment

Harsher Consequences for Repeat Offenders

Minnesota’s new DWI laws place a strong emphasis on repeat offenders, imposing stricter and longer-lasting penalties.

Longer License Revocation and Cancellation Periods

  • Second DWI in 20 years — mandatory 2-year revocation
  • Third DWI in lifetime — mandatory 6-year cancellation
  • Fourth DWI in lifetime — mandatory 10-year cancellation

Once your license is cancelled, you must apply for a new one. This process generally involves successful completion of ignition interlock and treatment requirements to get your license back.

Mandatory Ignition Interlock

To fully regain driving privileges, drivers convicted of a second or subsequent DWI are now required to install and maintain an ignition interlock device in their vehicle. The new timelines are as follows:

  • Second DWI in 20 years — mandatory 2-year ignition interlock period
  • Third DWI in lifetime — mandatory 6-year ignition interlock period
  • Fourth DWI in lifetime — mandatory 10-year ignition interlock period

Violating ignition interlock program rules — such as blowing over 0.02 in the interlock device, tampering with the device, or driving a vehicle without a device — can result in serious penalties that delay your license reinstatement, including a complete restart of the interlock period.

Additionally, it is now a gross misdemeanor to drive any vehicle without the required ignition interlock once your license is restricted.

Mandatory Treatment

Another major shift: in repeat cases, treatment is no longer optional. To fully regain driving privileges, drivers convicted of a second or subsequent DWI are now required to complete a licensed treatment program.

Changes to Temporary Licenses in Test Refusal Cases

Minnesota also updated its rules regarding temporary licenses issued after a DWI arrest under the implied consent law.

Previously, drivers typically received a 7-day temporary license after a revocation notice. Under the new law, temporary licenses now last 14 days. This change provides drivers with additional time to arrange transportation, consult with an attorney, decide whether to challenge the revocation, and begin the ignition interlock process (if eligible).

While this may seem like a small procedural change, it can make a meaningful difference in the critical early days of a DWI case — especially in test refusal cases, which often carry harsher penalties.

Why These Changes Make Legal Representation More Important Than Ever

Minnesota now has some of the strictest DWI laws in the country. The consequences of a DWI case extend far beyond the courtroom and deeply impact a person’s ability to travel, work, and maintain independence.

Key issues that require skilled legal advocacy in your DWI case include:

  • Challenging the legality of the traffic stop, DWI investigation, or arrest
  • Contesting breath or blood test results
  • Fighting license revocation through implied consent proceedings
  • Advising on ignition interlock eligibility and compliance
  • Minimizing the long-term consequences of repeat offenses
