The Illinois written test has 35 questions, and you need to answer at least 28 correctly to pass
The Illinois Secretary of State administers one written test for your learner's permit. That test contains 35 multiple-choice questions. You must answer at least 28 of them correctly — that is 80 percent — to pass and move forward to the road test.
The test covers rules of the road, road signs, safe driving practices, and what to do in emergency situations. All questions come from the Illinois Driver's Manual, which the Secretary of State publishes online for free. You can read the manual before you test, and many people do.
You get one attempt per visit to the Secretary of State facility. If you do not pass, you can return and test again, but you will need to schedule another appointment and pay the test fee again.

What topics the 35 questions cover
The Illinois test does not break down its 35 questions by topic in a published way, but the Driver's Manual does. The manual is organized into chapters on vehicle control, traffic signs and signals, right-of-way rules, speed limits, parking, driving in different weather and road conditions, and what to do after an accident. Questions are drawn from all of these areas.
Road signs make up a significant portion of the test. You should be able to recognize and explain the meaning of stop signs, yield signs, warning signs (like curves ahead or pedestrian crossing), regulatory signs (like speed limit or no parking), and guide signs. The test will show you a sign image and ask what it means or what you should do when you see it.
Right-of-way questions are common because they directly affect safety. You will see scenarios: a car approaching from the left at an intersection, a pedestrian in a crosswalk, a school bus with its lights on. The test asks who has the right of way and what you should do.
How the test is administered at the Secretary of State
You take the test at a Secretary of State Driver Services facility in person. You cannot take it online. When you arrive for your appointment, a staff member will check your identification and direct you to a testing station — either a computer terminal or a paper test, depending on the facility.
You have a set amount of time to complete all 35 questions. The time limit varies slightly by facility, but you typically have 20 to 30 minutes. This is enough time if you read carefully; rushing is the most common reason people miss questions they could have answered.
Once you finish, the test is scored when ready if you are testing on a computer. If you took a paper test, staff will grade it while you wait. You will know your pass or fail status before you leave the facility.
How to prepare using the Illinois Driver's Manual
The Illinois Secretary of State publishes the Driver's Manual online as a PDF. You can read it, read it on screen, or print it. The manual is the only official source for test questions — everything on the test comes from it, and nothing on the test comes from anywhere else.
Read the manual section by section. Take notes on road signs, speed limit rules, right-of-way scenarios, and parking rules. Many people find it helpful to read a section, then close the manual and write down what they remember, then check their notes against the manual.
Some people use practice tests to get used to the format and pacing. Practice tests are not official, but they follow the same structure and cover the same topics. They can help you identify which areas you need to study more, but they are not a substitute for reading the manual itself.
What happens if you do not pass on your first attempt
If you score below 28 out of 35, you do not pass. You will receive a score report showing how many questions you answered correctly. The report does not break down which topics you missed, but you can use your score to decide whether to study the entire manual again or focus on the areas where you felt less confident.
You can retake the test, but you must schedule a new appointment and pay the test fee again. There is no waiting period between attempts in Illinois — you can test again the next day if you want to, though most people take a few days to study more.
Each time you test, you get a new set of 35 questions. The questions are different, but they cover the same topics and come from the same manual.
Differences between the learner's permit test and the road test
The written test and the road test are separate. Passing the written test does not mean you pass the road test, and vice versa. You must pass both to get your license.
The written test is 35 questions about rules and signs. The road test is a 20-minute drive with an examiner in your car. The examiner watches how you handle the vehicle, follow traffic laws, and respond to other drivers and pedestrians. The road test has no questions — it is a performance test.
You can take the written test before you have much driving experience. Many people pass it after a few weeks of studying the manual. The road test requires more practice — most people spend several months driving with a learner's permit before they feel ready.
Common mistakes on the Illinois test
The most common mistake is misunderstanding right-of-way rules at intersections. Many people think they have the right of way when they actually do not. Read the right-of-way section of the manual carefully and work through the scenarios slowly.
Another common mistake is confusing similar road signs. Warning signs are yellow, regulatory signs are white or red, and guide signs are green or blue. If you can remember the color, you can often figure out the sign's purpose even if you are not sure of the exact meaning.
Speed limit questions trip up some test-takers because Illinois has different limits for different road types and conditions. School zones have lower limits, residential areas have lower limits, and highways have higher limits. The manual lists these clearly — memorize the numbers.
Frequently Asked Questions
Can I use my phone or take notes during the test?
No. You cannot bring phones, notes, or any reference materials into the testing area. You must answer all 35 questions from memory. This is why studying the manual before your appointment is essential.
What if I fail the test — do I lose my learner's permit?
No. Failing the written test does not affect your learner's permit status. You can keep driving with your permit and retake the written test whenever you schedule another appointment. Your permit remains valid until its expiration date.
Are the test questions the same every time, or are they different?
The questions are different each time you test. The test draws from a larger bank of questions, all based on the Illinois Driver's Manual. This is why studying the manual itself is more useful than memorizing specific practice test questions.
How long does it take to get my results?
You get your results when ready. If you test on a computer, the score appears on screen right away. If you test on paper, staff grade it while you wait, usually within a few minutes. You will know whether you passed before you leave the facility.
Do I have to pass the written test before I can take the road test?
Yes. You must pass the written test first. Once you pass, you can schedule your road test. You cannot take the road test without a passing written test score on file with the Secretary of State.
