Illinois CDL Road Test & Physical Requirements
The Illinois CDL skills and drive test normally checks vehicle inspection, basic control, and on-road driving. Practice the permit material first, then study pre-trip inspection and low-speed control so the skills test does not feel like a separate surprise.
Illinois CLP and CDL applicants should keep required DOT medical certification current and follow Secretary of State commercial driver requirements.
Before scheduling, confirm current fees, medical certificate rules, CLP holding periods, and appointment steps with Illinois Secretary of State.
