What Constitutes OWI?

In Wisconsin, the illegal act of drinking and driving is charged as operating a vehicle while intoxicated (OWI). A motorist may be charged with OWI if they have a blood alcohol concentration (BAC) of .08% or more, also called the prohibited alcohol concentration (PAC). Note that it is still possible to be charged with OWI even if the motorist has a BAC below .08% if they perform poorly in the field sobriety tests, showing obvious and dangerous impairment.

DUI/OWI Defense in Wisconsin

Refusals in Wisconsin

Did you receive a refusal in Wisconsin? Many times, when someone gets a refusal in Wisconsin they are confused. You might be wondering how you could have received an OWI when you refused the chemical test. In the state of Wisconsin the implied consent law indicates that anyone who operates a vehicle has the right to consent to a chemical test: blood, breath, or urine.

Illinois Drivers

Note that if you have an Illinois driver’s license and you get an OWI in Wisconsin, it is important to speak to an experienced attorney. Illinois tends to treat the first OWI conviction must harsher than Wisconsin in terms of the license revocation period, obtaining an occupational driver’s license, and applying to reinstate your license. A first offense in Illinois could result in a 1-year driver’s license revocation and a license reinstatement process that could take 2-3 years.

Commercial Driver’s License

A CDL Holder may choose to fight their OWI case since the penalties are much greater for a CDL holder than an individual with a regular driver’s license. When fighting a DUI it is crucial to have a lawyer look over your case to make sure you get the best defense and outcome. A lawyer can build a strong defense for you.

Unlike the first OWI offense in Wisconsin, If you have a second OWI offense within 10 years of your first offense it will be charged as a crime. Wisconsin increases the penalties for any person caught transporting a minor under the age of 16 while under the influence of alcohol and/or drugs.  If you were charged with an OWI causing injury it will increase the severity of the penalties for your OWI. A number of variables will determine the charges.
