Yes. Illinois allows a person tested by law enforcement to obtain an additional independent chemical test at the subject's own expense under 625 ILCS 5/11-501.2. The law requires the arresting agency to allow reasonable opportunity but does not require the agency to transport or arrange the independent test. The subject typically arranges a blood test at a hospital shortly after release. The independent result becomes admissible and can contradict the state's number, particularly on borderline cases where absorption or elimination timing matters. Denial of a reasonable opportunity may support suppression of the state's test. A Chicago DUI lawyer confirms opportunity was given and, when denied, files the motion.
