Every state in the Union has laws against drunk driving. However, it is important to know that the particular laws may vary between states.

Wisconsin is one of many states that has ignition interlock requirements after certain kinds of DUI convictions. According to the state of Wisconsin, you will have to install an ignition interlock device if you have had multiple DUIs, if you had a BAC higher than .15 at the time the police pulled you over, or if you refuse a breathalyzer test when stopped. 
 
What is ignition interlock? 
 
An ignition interlock device is a small breathalyzer a mechanic installs in your car. If you have an ignition interlock device installed, you must breathe into it as you are starting your car. If the device detects any alcohol on your breath, the car will not start.

 Once the car is operating, you will need to breathe into it at regular intervals. This is to ensure that you have not not consumed alcohol after starting the vehicle. 
 
Can I “wait it out?”
 
It is of course possible to choose not to drive after receiving a DUI. However, there is no way of waiting out an ignition interlock order. Even if you choose not to drive in the direct aftermath of a DUI conviction, the requirement for ignition interlock will still stay on your record. If at any point in the future you wish to obtain a driver’s license, the requirement will still be there. 
 
If you require an ignition interlock device, the burden for payment is on you. However, if you can prove need to the state, you may be eligible for a 50% reduction in cost.
