Covers the FMCSA General Knowledge core every IL CDL applicant is tested on - 49 questions on vehicle inspection, basic control, and safe driving practices, with 39 correct to pass.
Illinois CDL General Knowledge Practice Test 2: what to expect and what trips drivers up
Round two raises the difficulty. This CDL general knowledge test practice set for 2026 pulls fresh Illinois CDL test questions and answers across inspection, cargo, hazard perception, night and winter driving, emergencies, and hours of service, so you are not simply re-reading what you already got right the first time.
Treat it as an Illinois CDL permit test rehearsal. The same written commercial driver's license practice test material stands behind the Commercial Learner's Permit, and the format on exam day is fixed: 50 questions, 80 percent to pass, 40 correct answers minimum. Score in the low forties consistently and you are ready; score in the thirties and you have found your weak chapter.
After each run, take the misses back to the Illinois CDL Manual and read the full section rather than the single sentence that would have saved you. That habit is what turns a commercial drivers license practice test into real preparation for the Illinois Secretary of State exam.
Every question traces back to the Illinois CDL Manual - skim the right-of-way and signs chapters before your retake.
