Understanding Minnesota’s New DUI Laws (Effective August 1, 2025)
By Sullivan Rice
Minnesota recently enacted its most significant overhaul of impaired-driving laws in years. These changes, effective August 1, 2025, fundamentally alter how the state handles DUI (technically “DWI” — Driving While Impaired) cases — especially for repeat offenses. If you or someone you care about is charged with impaired driving, it’s crucial to understand these updates and how they can impact your rights and future.
Expanded “Look-Back” Period
One of the biggest changes is the extension of the “look-back” period — the time frame during which prior DWI convictions can be counted to increase penalties.
Old law: 10-year look-back period
New law: 20-year look-back period
Under the updated law, a DWI conviction from as long as two decades ago can now affect your current case. That means an offense you thought was long behind you may still influence penalties today.
Longer and Broader Ignition Interlock Requirements
An ignition interlock device (IID) is a breathalyzer installed in a vehicle that prevents it from starting if alcohol is detected. Minnesota now requires many more drivers to use these devices — and for much longer periods — if they have previous offenses:
1 prior DWI within 20 years: 2-year IID requirement
2 prior DWIs: 6-year IID requirement
3 or more prior DWIs: 10+ years on IID — and in serious cases (like crashes with death or severe injury), lifetime IID use can be imposed.
Additionally, driving without a required IID is no longer just an administrative violation — it’s now a gross misdemeanor, which may include jail time and fines.
Mandatory Treatment Before License Reinstatement
Under the new law, anyone seeking to regain full driving privileges after a DWI must complete a licensed substance use disorder treatment program. This requirement applies even for some first-time offenses — a major shift from prior rules.
Temporary License and Administrative Changes
Minnesota also extended the period drivers can legally operate on a temporary license after a DWI arrest from 7 days to 14 days, giving individuals more time to make arrangements while they decide how to respond to charges.
On the administrative side, the law allows drivers to begin the ignition interlock program before paying the full license reinstatement fee — but the fee still must be paid before a standard license is restored.
Why These Changes Matter
These updates reflect Minnesota’s effort to reduce repeat impaired driving and improve public safety, especially following tragedies involving intoxicated drivers. But the new rules also raise the stakes dramatically for anyone charged with a DWI:
Older convictions can still count against you.
Longer IID periods mean extended monitoring of your driving.
Non-compliance with ignition interlock can lead to criminal charges.
Mandatory treatment adds another layer of legal and personal requirements.
That’s why a DWI charge today isn’t just about the night you were arrested — it’s about your future legal rights, driving freedom, and long-term consequences.
