The Illinois knowledge test is 35 questions and you need 28 correct (80%) to pass. Questions come from the official Illinois Rules of the Road (Illinois SOS) — with the state's heavy emphasis on road signs, signals, and Scott's Law.
The state doesn't publish its full pool. We author these from the same official source the real test uses — the Illinois Rules of the Road (Illinois SOS) — each grounded in a specific rule. Traffic laws are facts, not copyrightable.
It's completely free and no signup is required. Sign in only to save history and track weak areas.
Traffic laws and right-of-way, road signs and signals, safe-driving practices, alcohol/drugs and penalties, sharing the road, and parking/vehicle rules.
You can retake the Illinois knowledge test. Drill full 35-question simulations here until you're consistently above the 80% pass mark.
