Illinois has 50 questions on the written permit test, and you must answer at least 40 correctly to pass
The Illinois Secretary of State administers the written knowledge test for a learner's permit (also called a driver's license instruction permit). The test contains exactly 50 multiple-choice questions drawn from the Illinois Rules of the Road handbook. You need a score of 80 percent — which means 40 correct answers — to pass and move forward to the road test.
The questions cover traffic laws, road signs, safe driving practices, and rules specific to Illinois roads. Each question has four possible answers. You answer them on a computer at a Driver Services facility, and you receive your score when ready after you finish.

What the questions cover
The 50 questions test your knowledge of Illinois traffic laws and safe driving. Common topics include right-of-way rules, speed limits, parking regulations, what different road signs mean, how to handle intersections, and rules about following distance and lane changes.
Questions also cover situations specific to Illinois, such as rules for toll roads, handling weather conditions common to the state, and laws about distracted driving and seat belt use. Some questions ask about what to do in an emergency or how to respond to a police officer during a traffic stop.
The test does not include questions about vehicle maintenance or how to operate specific car controls — those are covered during the road test with an examiner.
How to prepare for the 50-question test
The Illinois Secretary of State publishes the official Rules of the Road handbook free online at cyberdriveillinois.com. You can read it on your computer, read it as a PDF, or request a printed copy at any Driver Services facility. The handbook contains all the information you need to answer the 50 questions correctly.
Many people study the handbook by reading it cover to cover, while others focus on the sections that cover the topics most likely to appear on the test: signs, right-of-way, speed limits, and parking. You can also take practice tests online through third-party websites, though the Secretary of State does not publish an official practice test with the exact same questions.
Some Driver Services facilities offer in-person study sessions or written materials to help you prepare. Call your local facility to ask what resources they have available.
Retaking the test if you don't pass
If you score below 40 correct answers, you do not pass. You can retake the test at the same Driver Services facility, often on the same day, though some locations may require you to wait or return another day. There is no waiting period between attempts, but you will pay the test fee again for each retake.
The test fee in Illinois is set by the Secretary of State and covers both the written knowledge test and the road test together. Check the current fee at cyberdriveillinois.com or ask at your local Driver Services office.
Where and when you take the test
You take the 50-question test at a Driver Services facility run by the Illinois Secretary of State. These offices are located throughout Illinois in most counties. You must bring a valid form of identification, proof of your Social Security number, and proof of your Illinois residency (such as a utility bill or lease).
Driver Services facilities operate during regular business hours, typically Monday through Friday, with some locations open on Saturday mornings. Hours vary by location, so check the Secretary of State website or call ahead to confirm the hours at the facility nearest you. You do not need an appointment at most locations, but some facilities accept appointments to reduce wait times.
After you pass the 50-question test
Once you pass the written test with a score of 40 or higher, you receive your learner's permit when ready. The permit allows you to drive with a licensed adult who is at least 21 years old sitting in the front passenger seat. You must carry your permit with you whenever you drive.
With your permit in hand, you can practice driving and prepare for the road test, which is the next step toward getting your full driver's license. The road test is administered by a Secretary of State examiner and tests your ability to operate a vehicle safely and follow traffic laws in real driving conditions. You must pass both the written test and the road test to receive your license.
Frequently Asked Questions
Can I take the permit test online from home in Illinois?
No. Illinois requires you to take the 50-question written test in person at a Driver Services facility. You cannot take it remotely or from home. You must go to an office, bring your identification and proof documents, and complete the test on a computer at that location.
What happens if I fail some of the 50 questions but not all?
Your score is based on the total number of correct answers. If you answer 39 questions correctly, you score 78 percent and do not pass — you need 40 correct (80 percent) to pass. There is no partial credit or second chance on individual questions; you either pass or retake the entire test.
Are the 50 questions the same every time someone takes the test?
No. The questions are drawn from a larger pool of possible questions, so different people taking the test on different days will see different questions. However, all questions come from the same Rules of the Road handbook, so studying that handbook prepares you for any version of the test.
How long do I have to answer the 50 questions?
Illinois does not publish a strict time limit for the written test. Most people finish within 30 to 45 minutes, but you are not rushed. The test is untimed, so you can take as long as you need to read each question and choose your answer.
Do I need to pass the 50-question test before I can take the road test?
Yes. You must pass the written knowledge test first. Only after you pass and receive your learner's permit can you schedule and take the road test with a Secretary of State examiner.
