What is an Ignition Interlock Device?
Also known as an IID, an ignition interlock device is a tool used to measure breath alcohol content. When installed in a vehicle, the user will not be able to drive a vehicle without passing the unit‚Äôs breath alcohol test.
When a driver starts the car, the IID will turn on, and the driver will need to breathe into a small device similar to a breathalyzer. If the driver passes the test, the vehicle will start. If the driver fails, the ignition interlock device will lock out, and a short-time suspension (a few minutes long) will occur prior to retesting. Every subsequent failed test after the first test will impose longer lockout times.
Depending on the type and severity of your sentence, some ignition interlock devices in Wisconsin integrate the use of ‚Äúrunning retests.‚ÄĚ As the driver is utilizing the vehicle, some IID‚Äôs require the individual to blow into the breathalyzer component every so often to dissuade those from bypassing the system. If the driver exceeds the breath alcohol level for driving, or avoids the test altogether while operating the vehicle, an auditory or visual warning system initiates and continues until the vehicle is shut off. The warning system could include horn honking, hazard and headlights flashing, etc.
Wisconsin DUI Laws Regarding an Ignition Interlock DeviceForty-seven states plus the District of Columbia allow the use of a breath alcohol ignition interlock device (BAIID) for repeat DUI offenders. The state of Wisconsin DUI laws indicate that first-time offenders qualify for the ignition interlock device if sobriety tests indicate the individual has an alcohol concentration of .15 or higher.
In 2009, the Wisconsin Act 100 was passed to increase the penalties for DUI and OWI offenders. In this Act, the Wisconsin DUI laws require IIDs to be mandatory for offenders convicted of:
- First OWI offense with .15 or higher alcohol concentration
- Second and repeat OWI offenses
- Refusals for sobriety testing
