What Are the Potential Defenses Against a DUI Charge in Illinois? Facing DUI criminal charges in the state of Illinois? Combs Waterkotte attorney Joshua Boardman discusses possible defenses used in Illinois DUI cases. A defense attorney may challenge whether the officer had reasonable suspicion to stop the vehicle or probable cause to make the arrest. Other defenses may focus on the reliability of field sobriety tests, breathalyzer results, or chemical testing procedures. Errors in police reports, improper testing protocols, or violations of constitutional rights can sometimes weaken the prosecution’s case. Understanding the best DUI defenses in Illinois can be critical when fighting DUI charges and protecting your future.

Interview Transcript

Scott Michael Dunn: So what are the potential defenses against a DUI charge in Illinois?

Joshua Boardman: You want to start at the beginning. Was there reasons for the stop? Was there proper investigation done by the law enforcement officer? Was all equipment calibrated? Were they properly trained on it? Are there any extenuating circumstances as far as justifications for performing poorly on a field sobriety test? Different things like that.
