How Many Ignition Interlock Violations Can You Have in Minnesota?
If you’ve been ordered to use an ignition interlock device (IID) in Minnesota, you’re likely working toward getting your driving privileges back. But repeated violations can delay or even derail that process. Understanding what counts as a violation and how many are allowed is key to staying compliant and getting your license reinstated.
What Is an Ignition Interlock Device?
An ignition interlock device is a small breathalyzer installed in a vehicle to prevent someone from starting the engine if alcohol is detected on their breath. The driver must blow into the device before starting the car and periodically while driving.
In Minnesota, IIDs are required for:
- Drivers with multiple DWI convictions.
- First-time offenders with a high blood alcohol content (0.16 or higher).
- Drivers seeking early reinstatement of their license through the Ignition Interlock Device Program.
The program is managed by the Minnesota Department of Public Safety (DPS), Driver and Vehicle Services (DVS) Division.
What Counts as a Violation?
Violations can happen in several ways, including:
- Failed breath tests.
- Missed or skipped rolling retests while driving.
- Tampering with or attempting to circumvent the device.
- Failure to report for calibration or required service.
- Operating a vehicle without a device installed, if mandated.
Each violation is logged and reported to the DVS by the monitoring agency or interlock vendor.
How Are Violations Monitored?
Interlock devices are equipped with data recorders that capture:
- Test results (pass/fail)
- Time stamps
- Photos or video (depending on device)
- GPS data
- Attempts to tamper with the system
This information is uploaded to the DVS regularly, typically during required monthly service appointments.
How Many Violations Are Allowed Before There Are Consequences?
Minnesota doesn't have a specific fixed number of "allowed" violations before penalties apply. Instead, each violation can lead to a program extension or a restart, depending on severity and frequency.
According to the Minnesota DPS Ignition Interlock Program Guidelines:
“Any program violation may result in a restart of the revocation period, cancellation of driving privileges, or a program reset.”
This means even one violation can set you back, especially if the offense suggests intentional misuse or non-compliance. The consequences of each violation depend on factors like the type of violation, prior driving record, and the discretion of authorities. However, repeated violations can lead to extensions of the ignition interlock program period or even termination from the program.
Legal and Administrative Consequences
The consequences of repeated violations include:
- Extension of your interlock period (e.g., starting your required time over).
- License cancellation, especially if the violation suggests tampering or circumvention.
- Permanent ineligibility for reinstatement in extreme cases.
- Court penalties if the violation leads to criminal charges (e.g., for driving without an IID).
Your interlock vendor must report all violations to the DPS, and the agency will determine the next steps.
Tips to Stay Compliant
To avoid setbacks in the program:
- Always follow testing prompts.
- Don’t consume alcohol before driving, even in small amounts.
- Keep your service appointments—calibration is required monthly.
- Don’t let anyone else blow into the device on your behalf.
- Call your vendor immediately if you have a mechanical issue.
If you believe a violation was recorded in error (e.g., due to mouthwash or a false positive), document the situation and notify your vendor right away.
Should I Speak with a DWI Attorney?
