Let’s be honest: no one plans to get a Driving While Impaired (DWI) charge. But if you’ve ever had one in the past—or know someone who has—there’s a major update in Minnesota law that deserves your attention. In 2025, the Minnesota Legislature passed a new bill that significantly strengthens the state’s DWI laws.

New Legislation

While the legal language can be tricky, there are real serious implications attached to the new legislation. The changes include: the DWI “lookback” period just doubled—from 10 years to 20 years; ignition interlock requirements got tougher, especially for repeat offenders; and other smaller changes now make things like license reinstatement and compliance even more complex.

Confused by all the changes? You are not alone—and we are here to make it easier to understand.

What is the "Lookback Period"?

Let’s start with the “lookback period.” This refers to the length of time the court is allowed to review your past DWI convictions when determining the severity of a current DWI charge. If you have had prior offenses within that period, the new charge can be “enhanced”—meaning you could face steeper penalties, such as longer jail time, higher fines, extended license revocation, and mandatory use of an ignition interlock device.

Previously, Minnesota’s lookback period was 10 years. So, for example, if you had a DWI in 2012 and were arrested again in 2024, your new charge would be treated as a first-time offense, because the earlier conviction fell outside the 10-year window.

Under the new law, the lookback period has been extended to 20 years. That means a DWI from 2005 could now resurface and significantly impact your current case. An offense you may have thought was behind you could once again be used to enhance penalties.

In addition to this major change, Minnesota is also increasing the required use of ignition interlock devices for repeat offenders, which is the breathalyzer device installed in vehicles that require the driver to provide a clean breath sample before the engine will start.

Here’s the new breakdown:

• 1 prior DWI: 2 years of interlock
• 2 priors: 6 years
• 3 or more: 10 years

Now, individuals with a prior DWI conviction or license revocation within the past 20 years may face forfeiture of their vehicle if charged with a new qualifying DWI offense. This is a major shift from the previous 10-year look-back period and significantly broadens the number of cases where forfeiture may apply. However, the law also offers important protections: drivers who voluntarily enter and remain compliant with the ignition interlock program may be eligible for a stay of forfeiture, potentially allowing them to keep their vehicle while the case is pending.

On top of that, a DWI is what we call an enhanceable offense, meaning that the more prior DWI convictions you have on your record, the more severe the consequences can become. Repeat offenses often lead to increased jail time, steeper fines, longer license revocations, and extended ignition interlock requirements, among other penalties. The good news? Knowledge is power—and taking action early can make all the difference. The most important step you can take is to speak with an experienced criminal defense attorney.
