What the Illinois written test covers and how to study for it
The Illinois written driving test is a 35-question multiple-choice exam that covers road signs, traffic laws, and safe driving practices specific to Illinois. You need to score at least 28 correct answers (80 percent) to pass. The test draws from the Illinois Driver's Manual, which the Secretary of State publishes free online and in print at any Driver Services facility.
The actual test questions come directly from material in that manual. This means you can study the exact content that will appear on your exam — there are no trick questions or content outside the manual's scope. Most people who read through the manual once and take a practice test know what to expect on test day.
You take the written test at a Driver Services facility in person. You cannot take it online or by mail. The test is offered in English and several other languages, and you can request a reader or other accommodation when you schedule your appointment.

Where to find the official Illinois Driver's Manual
The Secretary of State publishes the Illinois Driver's Manual online at cyberdriveillinois.com. You can read it there, read it as a PDF, or order a printed copy. The manual is also available in Spanish and several other languages on the same website.
If you prefer a printed copy, you can pick one up free at any Driver Services facility when you go in to take your test, or you can request one by mail through the Secretary of State's office. Many libraries and high schools also keep copies on hand.
The manual is divided into chapters covering traffic signs, right-of-way rules, speed limits, parking, alcohol and drugs, seat belts, and other Illinois-specific laws. Read through the entire manual at least once before you take a practice test. Most people find they can read it in two to three hours.
How to use practice tests effectively
Practice tests show you the question format and help you identify which topics you need to study more. The Secretary of State does not publish an official practice test, but several free practice tests are available online through third-party websites. These tests use questions modeled on the real exam and cover the same topics from the Driver's Manual.
Take a practice test after you have read through the manual once. Score yourself and note which questions you missed. Go back to the manual and reread the sections that cover those topics. Then take another practice test a few days later to see whether you have improved.
Do not memorize practice test questions word-for-word. The real test will ask about the same rules and signs, but the wording will be different. Focus on understanding the rule or concept behind each answer, not just picking the right letter.
What to bring and expect on test day
Bring a valid form of identification — a passport, birth certificate, or state ID card. You will also need proof of your Social Security number and proof of your Illinois residency (a utility bill, lease, or bank statement with your name and address). Check the Secretary of State website for the complete list of acceptable documents before you go.
Arrive at least 15 minutes early. You will check in at the front desk, and a staff member will verify your documents and take your photo. You will then be called to a testing station where you sit at a computer or receive a paper test, depending on the facility.
You have up to three hours to complete the 35 questions. You can go back and change your answers before you submit. Once you submit, the computer or staff member will tell you when ready whether you passed. If you pass, you will receive a learner's permit that day. If you do not pass, you can retake the test, usually the same day or within a few days.
Retaking the test if you do not pass
If you score below 28 correct, you do not pass and must retake the test. You can usually schedule a retest the same day or within a few days at the same facility. There is no waiting period between attempts in Illinois.
Before you retake the test, go back to the Driver's Manual and focus on the topics where you struggled. If you missed questions about right-of-way, for example, reread that chapter carefully. Take another practice test to check your understanding before you go back to the facility.
Most people pass on their second or third attempt. If you are still struggling after three attempts, consider studying with a friend or asking a parent or teacher to quiz you on the manual's content.
What happens after you pass the written test
Once you pass the written test, you receive an Illinois learner's permit (also called a Graduated Driver License or GDL permit). This permit lets you practice driving with a licensed adult in the car, but it comes with restrictions — you cannot drive alone, and there are limits on when you can drive and how many passengers you can have.
You must hold your learner's permit for a certain amount of time before you can take the road test. The length of time depends on your age. After you meet the permit holding period, you schedule a road test at a Driver Services facility. The road test is a separate exam where a state examiner watches you drive and evaluates your ability to handle a vehicle safely.
