Minnesota’s ignition interlock device program has undergone its most significant transformation in years. Effective August 1, 2025, new legislation expanded who must participate, extended how long participation is required, and added new consequences for violations. If you are facing a DWI in Minnesota or are already navigating the license reinstatement process, understanding the current state of the ignition interlock program is essential.
Sieben Edmunds Miller was among the first law firms in Minnesota to publish a comprehensive guide to the August 2025 changes. Here is what every driver needs to know.
What Is an Ignition Interlock Device?
An ignition interlock device (IID) is a breath-testing instrument installed directly in your vehicle’s ignition system. Before starting the vehicle, you must provide a breath sample by blowing into the device. If the device detects alcohol above a set threshold—typically 0.02 percent in Minnesota—the vehicle will not start. The device also requires periodic rolling retests while the vehicle is in motion. It cannot shut off a running engine, but failed retests are recorded as violations and reported to the Minnesota Department of Public Safety.
Modern ignition interlock devices include cameras that photograph or video-record each breath test to confirm that the registered driver is the one providing the sample. This prevents someone else from blowing into the device on the driver’s behalf.
Who Is Required to Use an Ignition Interlock Device in Minnesota?
As of August 1, 2025, the ignition interlock program is mandatory for a broader group of drivers than ever before. The new law requires participation from:
- All repeat DWI offenders within a 20-year lookback window (previously 10 years).
- Drivers convicted of criminal vehicular homicide (CVH) or criminal vehicular operation (CVO) involving alcohol—a new category added by the 2025 legislation.
- Any driver whose license has been revoked for a DWI-related offense who wishes to legally drive again.
A driver who operates a vehicle without a required ignition interlock device now faces a gross misdemeanor charge—a significant upgrade in the criminal consequences for non-compliance.
How Long Must You Participate in the Ignition Interlock Program?
The length of required participation depends on your DWI history under the new 20-year lookback framework:
- One prior DWI within 20 years: Two years of ignition interlock required.
- Two prior DWIs: Six years of ignition interlock required.
- Three or more prior DWIs: Ten years of ignition interlock required.
- Criminal vehicular homicide or operation with death or serious injury: Fifteen years or longer.
These periods must be completed in full before you can be reinstated to a standard driver’s license. Any violation—such as a breath test reading over 0.02—can result in the required time being extended or reset. The program operates on a compliance-based removal model, meaning you must demonstrate a period of clean compliance before being released.
Mandatory Treatment Under the 2025 Law
One of the most important new requirements under the August 2025 legislation is that all ignition interlock participants must complete a licensed substance use disorder treatment or rehabilitation program before their standard driving privileges can be restored. Previously, not all participants were required to complete formal treatment. This change reflects a broader policy shift toward treating DWI as a public health issue as well as a public safety one.
Practical advice: if you are already in the ignition interlock program or expect to enter it, begin exploring treatment options immediately. Completing treatment early and maintaining documentation of your participation will help streamline the reinstatement process.
Ignition Interlock Device Cost in Minnesota
The cost of the ignition interlock program is borne entirely by the participant. Typical costs in Minnesota include an installation fee and a monthly lease fee. Installation runs roughly $70 to $150 depending on the provider, and monthly lease and service fees generally range from $90 to $140 per month, or approximately $2.50 to $3.50 per day.
For drivers experiencing financial hardship, Minnesota offers a financial assistance program through the Department of Vehicle Services. If your annual household income is below 150 percent of the Federal Poverty Guidelines, you may be eligible to pay only half of the regular installation and monthly service fees. Eligibility is determined by your probation officer, so speak with yours as early as possible if cost is a concern.
Prior to the 2025 changes, participants had to pay the $680 license reinstatement fee before starting the ignition interlock program. Under the new law, you can begin the program without making any upfront payment, though the fee must be fully paid before your standard license is reinstated.
Choosing an Ignition Interlock Device Provider
Minnesota approves multiple ignition interlock device manufacturers, and participants can choose any state-approved provider. All devices must meet Minnesota Department of Vehicle Services standards. Approved providers operate service centers throughout the state where participants go for scheduled monthly calibration and monitoring visits. The device data is transmitted to DVS and reviewed for compliance.
When selecting a provider, consider factors such as service center locations near your home or work, customer service reputation, and overall costs. DVS allows participants to change manufacturers at any time, so you are not locked in if your initial choice is not working for you.
Driving Restrictions While on Ignition Interlock
While participating in the ignition interlock program, several restrictions apply. You must have the device installed in every vehicle you operate personally. Company-owned vehicles are an exception—you may drive an employer’s vehicle without an interlock during normal working hours, but only with your employer’s written consent and only for work-related driving. You must carry proof of insurance on all vehicles in the program and may not operate any vehicle that is not equipped with the interlock.

Frequently Asked Questions About the Ignition Interlock Program
Which ignition interlock device is considered most reliable for preventing DWI incidents?
Minnesota approves multiple ignition interlock device manufacturers, and all must meet the same state standards set by DVS. The most important factor is choosing a provider with convenient service centers and a strong track record of accurate reporting. Popular providers in Minnesota include Intoxalock, Smart Start, and RoadGuard. Consult your attorney or probation officer for guidance based on your location.
How much does an ignition interlock device cost in Minnesota?
Installation typically costs between $70 and $150. Monthly lease and service fees range from approximately $90 to $140 per month. Financial assistance is available for those who qualify based on household income. The $680 license reinstatement fee can now be paid in installments under the 2025 law.
What do ignition interlock laws require after a DWI conviction in Minnesota?
As of August 1, 2025, repeat DWI offenders must use an ignition interlock device for two to ten years depending on the number of prior offenses within the 20-year lookback window. All program participants must also complete a licensed substance use disorder treatment program before their standard license is reinstated. Driving without a required interlock is now a gross misdemeanor.
How does the ignition interlock program work for drivers seeking license reinstatement?
Eligible drivers enroll in the program through DVS, have the device installed by an approved provider, and maintain scheduled monthly service visits. The device reports breath test results and any violations to DVS. Drivers must maintain compliance—no readings above 0.02—throughout the required program period and complete treatment before their standard license is reinstated.
What restrictions apply when driving with an ignition interlock device installed?
You must install the device in all vehicles you personally operate. You cannot drive any vehicle without the interlock unless it is an employer-owned vehicle driven during work hours with written employer consent. You must submit to rolling retests while driving, carry proof of insurance, and keep your service appointments. Any failed test is recorded as a violation and may extend your required participation period.
