1 What score do you need to pass the Illinois knowledge test?
Illinois requires 80% (28 of 35 questions) to pass.
2 For drivers under 21 in Illinois, the blood-alcohol limit is:
Illinois has zero tolerance: any measurable alcohol for a driver under 21 can mean license suspension.
3 Heavy snow is falling on a Chicago expressway. You should:
Never use cruise control on slick roads; slow down, leave extra space, and make gentle inputs.
4 What is the shape of a STOP sign?
Only the STOP sign is an octagon. The unique 8-sided shape lets drivers recognize it even when snow or dirt hides the wording.
5 A solid yellow line on your side of the center line means:
A solid yellow line on your side means you may not cross it to pass. A broken yellow line on your side would allow passing when safe.
6 Under good conditions, the minimum safe following distance is about:
Use the 3-second rule: pick a fixed point, and you should pass it at least 3 seconds after the car ahead. Add more time in rain, fog, or at higher speeds.
7 A triangular (downward-pointing) sign tells you to:
A downward triangle is always a YIELD sign. Slow down, be ready to stop, and give the right-of-way to traffic and pedestrians already in the intersection.
8 When a traffic light is flashing red, you must:
A flashing red light has the same meaning as a STOP sign: come to a full stop, then proceed only when it is safe.

High beams reflect off fog and reduce visibility. Use low beams (and fog lights if equipped), and slow down.
10 A school bus ahead stops and turns on its flashing red lights on an undivided road. You must:
On an undivided road, traffic in BOTH directions must stop for a school bus with flashing red lights and remain stopped until the lights are turned off.

Illinois runs a 35-question exam (28 to pass) built around right-of-way, road signs, and the state's tough alcohol and 'Scott's Law' move-over rules. Read the Illinois Rules of the Road once, then drill in short daily sets so the wording feels familiar.
Drivers under 18 must complete driver education first; the original knowledge test is taken in person at a Secretary of State Driver Services facility.
Retaking the knowledge test is generally covered by your application.
The driving test is included in the graduated licensing process.
Driver Services facilities accept card, cash, and check. Confirm current fees with the Illinois SOS.
Local statutes to flag
Illinois mixes Chicago lake-effect snow, black ice, dense prairie fog, and strong crosswinds on open interstates. SOS questions like to test winter following distance, skid recovery, and reduced-speed habits.
Finish driver education (if under 18), then book a Driver Services appointment. Arrive early with ID, SSN, residency proof, and consent forms. Use the wait to review alcohol-law and Scott's Law questions, then check in calm and ready.
