Not sure how it works in MN or IA but in IL when you get a drivers license you give implied consent to the cops to administer a breathalyzer. If you don't , two things happens: you automatically lose your license for something like 6 months for the refusal and they take you to a hospital, make a call for a search warrant and draw blood to get your BAC. Same result.<quoted text>
What does that have to do with refusing a Breathalyzer?
The only way you can get out of it is if the cop did not have probable cause to pull you over in the first place.
