Illinois DMV is administered by the Illinois Secretary of State, headquartered in Springfield. The official Illinois written knowledge exam has 35 questions, and drivers must answer 28 correctly (80%) to pass. Our practice tests match the exact format, topics, and difficulty of the real Illinois DMV test.
What makes the Illinois DMV test unique?
Illinois's test emphasizes rail-grade crossings (the state has the second-most in the US), Scott's Law (move-over for emergency vehicles), and bicycle right-of-way on Chicago-area streets.
Scott's Law: drivers must slow down and change lanes away from stopped emergency, tow, or maintenance vehicles — violations start at $250.
Teen applicants also take a 20-question road signs section that must be passed with 15 correct.
