Since drunk driving is very dangerous, all 50 states have stringent laws against the practice. However, each state has slightly different laws and slightly different penalties. It is important to be aware of the laws in Wisconsin. 

Like many states, Wisconsin has an ignition interlock requirement for certain types of OWI offenders. According to the Wisconsin Department of Transportation, repeat OWI offenders, OWI offenders who have high alcohol concentration, and drivers who do not provide a breath or blood sample when requested must install ignition interlock devices. 
 
What is an ignition interlock device? 
 
An ignition interlock device is a breathalyzer that a third-party company installs in your car. While the ignition interlock device is in your car, the vehicle will not start unless you breathe into it first. The device will measure if there is any alcohol on your breath. If there is, the car will not start. 
 
Ignition interlock devices prevent drunk driving before it begins. You will also need to breathe into the device periodically to prove that you have not ingested alcohol since turning on the vehicle. 
 
When will I get my regular license back? 
 
The length of time you need to have an occupational license for driving (which means that you need to have an ignition interlock device installed) depends on your particular case. 
 
Persons who have an income that is less than 150% of the federally designated poverty level may be eligible for lower costs associated with ignition interlock devices. Most of the time, if you need an ignition interlock device to legally operate a vehicle you will be responsible for all of the costs associated with it.
