Take a free, untimed Illinois DMV practice test in the real exam format: 35 questions, 28 correct to pass. Fresh random questions every attempt.
The Illinois knowledge test is a single 35-question exam covering road signs and the rules of the road together. You need 28 correct (80%) to pass.
Answer: The vehicle on the left must yield to the vehicle on the right
When vehicles arrive simultaneously at an uncontrolled intersection, the vehicle on the left yields to the vehicle on its right.
Right-of-Way
Answer: Wait for the green, unless a sign specifically allows a turn on the red arrow, or you are turning left from a one-way onto a one-way after stopping and yielding
A steady red arrow generally prohibits turning until green, except where a sign allows it, or for a left turn from one one-way street onto another after stopping and yielding.
Signals
Answer: 5 points
Speeding 1-10 mph over the limit adds 5 points to an Illinois driving record.
Points & Suspension
Answer: Toward the curb
Facing downhill with a curb present, turn your wheels toward the curb so the car rolls into it if it moves.
Parking Rules
Answer: Age 2, unless the child weighs over 40 lbs or is over 40 inches tall
Illinois requires rear-facing seating until age 2, unless the child exceeds 40 pounds or 40 inches tall, whichever comes first — effective since January 1, 2019.
Child Passenger Safety
Answer: The vehicle on the left yields to the vehicle on its right
At a four-way stop, the driver who stopped first generally goes first; for a true simultaneous stop, the left yields to the right.
Right-of-Way
Answer: The protected turn is ending, or you may turn after yielding to oncoming traffic
A yellow arrow (steady or flashing) signals that the protected phase is ending, or that you may turn but must first yield to oncoming traffic.
Signals
Answer: 15 points
Speeding 11-14 mph over the limit adds 15 points.

Back to the full Illinois study route
Questions and exam format researched against Illinois's official driver handbook and state sources. Last verified 18 August 2026.
Illinois Secretary of State official "Rules of the Road" handbook (ilsos.gov, 2026 edition) and its official practice workbook; Illinois Administrative Code 92 §1040.20 (violation point values) and §1040.30 (suspension/revocation thresholds), via ilga.gov — researched and verified 2026-08-18. Exam format: ilsos.gov officially confirms a unified 35-question test (15 sign-identification + 20 rules-of-the-road, one combined pool with no separate sign-section gate). The passing score is NOT officially published on ilsos.gov; only third-party sources cite 80%, which this module uses (rulePassPct: 0.8) with this caveat noted explicitly rather than presenting it as confirmed. signCount/signPassCount are set to 0 per the app's unified-format convention, since the 15 sign questions are folded into the same 35-question pool as the 20 rules questions rather than gated separately. Known gaps deliberately NOT invented, per the research doc: exact dollar fines for work-zone speeding, seat belt, handheld-phone, and child-restraint violations (none published in the handbook); truck/bus no-zone footage figures (diagram shown but no numbers given); reckless driving has no mph threshold (conduct-based only, correctly reflected as such rather than inventing a number); Illinois does not use a curb-color system, so no colored-curb rules were written; no distracted-driving statistic is published. Re-verify periodically, as SOS handbook content, fees, and point/suspension thresholds change over time.
