Do you think it is possible to face OUI charges in Wisconsin if a police officer pulls you over in traffic and you have not consumed so much as a drop of alcohol beforehand? If you answered, "No," then you'd better keep reading. If you answered, "Yes," then you're likely aware that there are numerous conditions and commercial products that can cause false positive results on a preliminary alcohol screening test.
This test occurs at the scene of a traffic stop. This is different than a chemical Breathalyzer, which determines the amount of alcohol in your bloodstream. A preliminary test uses a mobile test device and merely detects whether or not there is alcohol on your breath. The only problem is that there are many things besides alcoholic beverages that happen to prompt such devices to register positive. You are in for quite a challenge if you plan to fight OUI charges in a Wisconsin court.
