Yes, under the zero tolerance framework at 625 ILCS 5/11-501.8. Any measurable BAC triggers administrative summary suspension. A criminal DUI charge under 625 ILCS 5/11-501 still requires either BAC of 0.08% or actual impairment proof. The chicagoduilawyer.net brand handles many cases where the detectable BAC was well under 0.08% but administrative consequences hit hard: three-month license suspension on first offense derails college semester driving, part-time employment, and family logistics. Defense on these cases challenges the traffic stop, the breath test calibration, and the officer's reasonable articulable suspicion before administrative penalties become final.
