In Wisconsin's Waukesha County, a drunk driving charge is formally referred to as Operating While Intoxicated (OWI). There are various ways to be charged with an OWI offense, including driving with a blood alcohol content (BAC) of 0.08 percent or higher; driving under the influence of an illegal drug or other controlled substance; driving with a noticeable measure of restricted or controlled substance in the blood; or driving under the influence of any intoxicant such as alcohol, prescription or over the counter medication, or an illegal or controlled drug.
When pulled over by the police, most people's first inclination is to volunteer information. Although it is generally not wise to refuse to speak with an officer asking routine questions, it would be wise to avoid embellishing or providing extra information. This is because the probability of incriminating yourself or providing more facts that support your guilt increases the more you speak. Rather, you should be polite, calm, and cooperative with the police.
