What is Commercial DUI Under 625 ILCS 5/11-501?

Commercial DUI means driving a commercial vehicle with a BAC of .04 or higher, or driving any vehicle with CDL holder status. This has a lower BAC threshold that can destroy commercial driving careers.

Unlike standard DUI cases, commercial DUI cases involve complex evidence including CDL regulations, commercial vehicle standards, and employment implications. However, these procedures may contain technical flaws and constitutional violations that experienced defense attorneys can challenge to win cases.

The key to defending commercial DUI charges lies in attacking the reliability of commercial testing standards and constitutional violations during arrest.
