What is an ignition interlock device (IID)?

An ignition interlock device is a car breathalyzer designed to prevent anyone under the influence from driving the vehicle. It requires a breath sample to be submitted below a pre-set state limit before it will allow the driver to start the vehicle. If the breath alcohol concentration (BrAC) is above the pre-set limit, the vehicle will not start. Ignition interlocks are also referenced as breath alcohol ignition interlock devices (BAIIDs)

Do ignition interlocks reduce recidivism rates (repeat offenses)?

Ignition interlock devices decrease the re-arrest rate by up to 67%. They also allow people to be responsible and productive in their lives after a DUI by allowing them to drive legally and safely.

Will an ignition interlock device damage my vehicle?

An Integrity ignition interlock device will not damage your vehicle. We are experts in working with a vehicle’s electrical system. Our Wisconsin Ignition Interlock service centers are staffed by in-house experts who are continuously working with new vehicles to ensure we are able to install safely in any type of vehicle.

How long does it take to install an ignition interlock device?
Please Allow in your schedule 1-2 hours for most vehicles for the install process.   We install all equipment in a very professional manner to avoid future problems with vibration and normal driving activity.
What happens if I fail the breath test when I am trying to start my car?

If you fail a breath test, your vehicle will not start. In some states, your Integrity Interlock system may enter into a temporary lock out, preventing you from submitting another sample for a few minutes. Once the temporary lock out is over, you will be able to submit another sample. Once you pass the test, you will be able to start your vehicle. In many states, too many failed attempts to start your vehicle will cause your device to go into a service lockout.

How does an Ignition Interlock device work?

Each event below is recorded by the device including dates, times, test results:

  • The driver will turn the ignition on.
  • The device will prompt the driver to provide a breath sample.
  • The driver must provide a sufficient breath sample.
  • The device’s fuel cell will measure the amount of alcohol in the breath sample.
  • If the amount of alcohol is below the pre-set state limit, the device will allow the driver to start the car.
  • If the amount of alcohol in the breath sample is not within the pre-set limit, the vehicle’s ignition will be disabled. The device will go into “Lockout” for a set period of time. Once the “Lockout” period has expired, the device will allow the driver to provide another breath sample.
  • Once the vehicle has been started, retests will be randomly required during operation of the vehicle. A failed or missed retest will not disable the vehicle’s engine; however the violation will be recorded. If required, the vehicle’s horn may sound and headlights may flash if a retest is failed or missed until a breath test is passed or the vehicle is shut off by the driver.
How do I apply for an occupational license?

To apply for an occupational license, you will need to fill out form (MV3027) listing the counties or states in which you will be driving, the time(s) of day you will be driving, etc. You can download form MV3027 by CLICKING HERE


Are Ignition Interlock Devices (IIDs) mandatory?

Ignition Interlock Devices (IIDs) will be mandatory for the following convictions:

  • ALL repeat OWIs
  • ALL refusals
  • ALL 1st offense OWI with an alcohol concentration of 0.15 or higher
  • IIDs are required for every vehicle owned by or registered to the offender, unless the vehicle is specifically exempted by the court.

IIDs must be ordered for a minimum of one year:

  • For operating privilege, restriction begins when offender is issued an occupational license or reinstates operating privilege (cannot “wait out” IID anymore).
  • For vehicles, courts may order the IID restriction to begin immediately.
  • Failure to install, removal, disconnection, tampering or circumvention violations result in a six-month extension of IID.
  • The minimum waiting period for occupational license is 45 days, for 2nd / subsequent OWIs. If no occupational license is issued, proof of IID installation is required for all vehicles owned and registered, before DMV can reinstate the offender’s driver license (cannot “wait out” IID).
Can I start my vehicle without taking a test?

No, you must provide a passing breath sample before your vehicle is allowed to start. Any tampering or attempted circumvention is recorded. This could affect your driving privileges and require you to keep your ignition interlock device installed longer. In many states, tampering with your interlock device may be considered a felony.

If someone else blows into my ignition interlock device who is intoxicated, will I be held responsible?

You are responsible for every sample blown into your ignition interlock device. However, we do recommend that you keep a log of when anyone else drives or attempts to submit a breath sample in your vehicle.
