- Pre-Trial Hearings: Your DUI attorney may challenge evidence, traffic stops, and test accuracy.
- Trial (if necessary): A judge or jury will determine whether you are guilty or not guilty.

We Win DUI Cases Other Lawyers Said Were Impossible
Some DUI defense lawyers will tell you that if you fail a breathalyzer test or field sobriety tests, there’s no way to win. That’s not true. We have successfully defended clients with high BAC readings, poor field sobriety test results, and seemingly impossible cases.
For example, in People of the State of Illinois v. J.A., our client was arrested for driving the wrong way on a four-lane road for over a mile at 2:00 a.m. Despite failing field sobriety tests and having a strong smell of alcohol, we successfully challenged the case based on officer testimony and procedural issues. The officer admitted that other than the wrong-way driving, the client’s driving was acceptable, and that in some foreign countries, people drive on the opposite side of the road. Additionally, the field sobriety tests were discounted due to a lack of video evidence. As a result, our client was found not guilty after a bench trial in Cook County.

The prosecution’s burden of proof becomes significantly more challenging, making refusal cases much more defensible.
