If you’re arrested for driving while impaired (DWI) in Minnesota, one of the biggest concerns is whether you’ll lose your driver’s license. Minnesota law allows certain drivers to regain limited driving privileges through the ignition interlock device (IID) program.
The program requires installing a small breath-testing device in your vehicle that measures alcohol levels before the car can start. If alcohol is detected, the engine will not start.
At Martine Law, our DWI attorneys help clients understand the ignition interlock program and explore whether it’s the best option for restoring their driving privileges.
Who is required to use the ignition interlock?
Not everyone charged with DWI has to use an ignition interlock. It is typically required for:
- Repeat DWI offenders
- Drivers with high blood alcohol concentration (BAC) (0.16% or higher)
- Drivers seeking to shorten or avoid long license revocations
- Drivers convicted of felony-level DWI
For many, the choice is either enroll in the IID program or remain without a license for months or years.
How the program works
The ignition interlock device is installed in your vehicle by a certified vendor. Here’s how it operates:
- Initial breath test: You must blow into the device before starting the car.
- Rolling retests: While driving, you may be required to blow again to ensure no alcohol was consumed after starting.
- Data recording: Each test result is logged and reported to the Department of Public Safety (DPS).
- Violations: If alcohol is detected or the device is tampered with, the violation is reported, and your time in the program may be extended.
License options under ignition interlock
Minnesota offers two main license types through the IID program:
- Limited license: Allows you to drive for essential purposes, such as work, school, or treatment.
- Full license with interlock restriction: You can drive anywhere, but only with the IID installed.
Which option you qualify for depends on your BAC level, number of prior DWIs, and other factors.
Costs of the ignition interlock program
The driver is responsible for the costs of participating in the program. Typical expenses include:
- Installation: $90–$150
- Monthly monitoring fee: $70–$120
- Removal fee: $50–$100
Over the course of a year, this can add up to more than $1,000. However, many clients see it as worth the expense to regain driving privileges.
How long must you use ignition interlock?
The length of time depends on the severity of the offense and prior record:
- First DWI with BAC under 0.16%: May not be required
- First DWI with BAC 0.16% or higher: 1 year
- Second offense: 1–2 years
- Third offense: 3–6 years
- Fourth or subsequent offense: At least 4 years, possibly longer
If you violate program rules, the timeframe may be extended.
Benefits of the program
While it may feel restrictive, the IID program offers key benefits:
- Lets you continue driving legally rather than facing a long suspension
- Demonstrates responsibility to the court and probation officers
- Helps maintain employment, education, and family responsibilities
- Can reduce the overall length of license revocation
Defenses and alternatives
Not everyone is automatically eligible, and some may want to challenge the requirement. A Minnesota DWI lawyer can help by:
- Challenging the validity of the breath test that triggered the requirement
- Reviewing whether the Department of Public Safety followed proper procedure
- Exploring options for limited driving privileges without ignition interlock
In some cases, successfully fighting the DWI charge altogether may prevent the need for IID.
Key takeaways

- It requires blowing into a device before starting your car and sometimes while driving.
- Costs and requirements vary depending on your record and BAC level.
