The Illinois permit test has 35 questions, and you must answer at least 28 correctly to pass

The written knowledge test for your Illinois learner's permit contains 35 multiple-choice questions. You need to score at least 80 percent — which means getting 28 questions right — to pass. The test covers rules of the road, road signs, safe driving practices, and Illinois-specific traffic laws. You take it at a Secretary of State facility when you explore for your permit.

The test is not timed in the sense that you are not rushed, but you should expect to spend 20 to 30 minutes on it. You answer questions on a computer at the testing station. If you fail, you can retake the test the same day or come back another day, depending on the facility's schedule.

Key Takeaways

  • You must answer at least 28 of 35 questions correctly to pass the Illinois permit test.

  • Questions are multiple-choice and taken on a computer at a Secretary of State office.
  • You can retake the test the same day if you fail, though some facilities may require you to return another time.

What the 35 questions cover

The Illinois permit test draws from the Illinois Rules of the Road handbook, which the Secretary of State publishes. Questions focus on practical driving situations you will face: when to yield, how to handle intersections, what different road signs mean, speed limits, parking rules, and what to do in bad weather or emergencies.

You will see questions about right-of-way — for example, who goes first at a four-way stop, or how to proceed at a traffic light turning green when pedestrians are still crossing. Other questions test your knowledge of Illinois-specific rules, such as seat belt laws, distracted driving rules, and what to do if a police officer pulls you over.

Road signs make up a significant portion of the test. You need to recognize warning signs (yellow diamonds), regulatory signs (white rectangles), and informational signs (green rectangles), and understand what each one means. Some questions show you a sign and ask what it indicates; others describe a situation and ask which sign applies.

How the test is scored and what happens if you fail

The Secretary of State's computer system scores your test when ready after you finish. You learn your result before you leave the testing station. If you pass, you receive your learner's permit that same day. If you score below 80 percent, you do not pass.

Illinois allows you to retake the test, but policies vary by location. Many Secretary of State offices let you retake it the same day; others require you to wait and return another time. There is no limit to how many times you can retake the test, but each attempt may require you to pay the permit process fee again — currently $5 for a learner's permit — depending on the facility's rules. Call your local Secretary of State office before your test to confirm their retake policy.

How to prepare for the 35-question test

The Secretary of State publishes the Illinois Rules of the Road handbook free online and in print at any Secretary of State office. This handbook contains nearly all the information tested on the permit exam. Reading it cover to cover is the most direct way to prepare.

Many people also use practice tests available online through third-party websites and apps. These are not official, but they follow the same format and cover the same topics as the real test. Taking practice tests helps you get used to the multiple-choice format and identify which topics you need to study more.

Study the road signs section carefully — it accounts for a meaningful portion of the test, and many people find it the hardest part. Spend extra time on right-of-way rules and Illinois-specific laws like distracted driving and seat belt requirements. If you struggle with a particular topic, go back to the handbook and reread that section before you test.

What to bring and what to expect at the testing station

Bring a valid form of identification — a passport, birth certificate, or state ID — and proof of your Social Security number. You will also need to bring proof of your Illinois residency, such as a utility bill or lease agreement. The Secretary of State office will tell you the exact documents needed when you call to schedule your appointment or when you arrive.

At the testing station, you will check in at the counter, provide your documents, and pay the permit fee if you have not already. A staff member will direct you to a computer terminal where you take the test. You sit alone at the terminal and answer the 35 questions. Once you finish, the system scores it and displays your result on the screen. If you pass, you proceed to get your photo taken for your permit. If you fail, you can ask about retesting options right there.

Frequently Asked Questions

Can I use my phone or notes during the permit test?

No. The Secretary of State does not allow phones, notes, or any outside materials in the testing area. You must answer all 35 questions from memory based on what you have studied. Attempting to use unauthorized materials can result in your test being voided and your process being denied.

What happens if I get exactly 28 questions right?

You pass. Twenty-eight correct answers out of 35 is exactly 80 percent, which is the passing score. You do not need to answer more than 28 correctly; 28 is the minimum required to pass and move forward with your permit.

Do all 35 questions count the same toward my score?

Yes. Each of the 35 questions is worth one point. There are no weighted questions or bonus points. Your score is straightforward the number of questions you answer correctly out of 35.

Can I see which questions I got wrong after I fail?

Policies vary by Secretary of State office. Some facilities provide feedback on which topics you missed; others do not. Call your local office to ask whether they review failed tests with you or provide a breakdown of your weak areas before you retake it.

Is the permit test different if I am under 18?

No. All applicants for an Illinois learner's permit take the same 35-question test, regardless of age. The content and passing score are the same for everyone.
