The Illinois written test has 35 questions, and you need to answer at least 28 correctly to pass
The Illinois Secretary of State administers a 35-question multiple-choice test for anyone seeking a driver's license or renewing one after a suspension or revocation. Each question has four possible answers. You must score at least 80 percent — which means 28 correct answers out of 35 — to pass and move forward to the road test portion.
The test covers material from the Illinois Driver's Manual, which the Secretary of State publishes and makes available online and at driver services facilities. The questions draw from sections on traffic laws, road signs, safe driving practices, and what to do in emergencies or collisions. The manual is the official source document, and studying it directly is more reliable than relying on third-party study guides that may contain outdated or incomplete information.

What the test covers and how questions are distributed
The 35 questions span several broad categories, though the Secretary of State does not publish an exact breakdown of how many questions fall into each topic. However, based on the manual's structure, you can expect questions on traffic signs and their meanings, right-of-way rules, speed limits and safe following distances, parking regulations, and what to do at intersections and railroad crossings.
A significant portion of the test addresses impaired driving, seat belt laws, and distracted driving — topics the state emphasizes heavily in its licensing materials. You will also encounter questions about vehicle maintenance, tire tread, and brake function, as well as scenarios involving pedestrians, cyclists, and motorcyclists. A smaller number of questions typically cover administrative matters like license renewal, vehicle registration, and insurance requirements.
The test is not designed to trick you. Questions are straightforward, and the correct answer is usually the safest or most legal option. If you have studied the manual thoroughly, you should recognize most scenarios presented.
How to prepare and what to expect on test day
The Illinois Secretary of State publishes the Driver's Manual in English and several other languages on its website. You can read it online, read it as a PDF, or request a printed copy at a driver services facility. The manual is organized by topic, making it practical to study one section at a time rather than trying to memorize everything at once.
Some people use practice tests available through third-party websites or apps, but these vary in accuracy and may contain errors. The official manual is always your most reliable source. If you use a practice test, cross-check any answers you are unsure about against the manual itself.
On test day, you will take the test at a driver services facility. You will be given a paper test or take it on a computer, depending on the location. You have a set amount of time to complete it — typically 30 minutes, though this can vary. You will not be allowed to use notes, phones, or reference materials. Bring a valid form of identification and any documents required for your specific situation (such as proof of residency if you are explore for the first time).
Retaking the test if you do not pass
If you score below 28 correct answers, you do not pass and will need to retake the test. You can schedule another attempt, though there may be a waiting period before you can test again. The exact waiting period and number of retakes allowed depend on whether you are a first-time applicant, renewing after suspension, or in another category — contact your local driver services facility or check the Secretary of State website for your specific rules.
Many people pass on their second or third attempt after spending more time with the manual. There is no penalty for retaking the test beyond the fee charged each time you test, which varies by facility.
Differences between the written test and the road test
The written test and the road test are separate events. Passing the written test does not mean you automatically pass the road test, and vice versa. You must pass both to receive your driver's license. The written test measures your knowledge of laws and safe practices; the road test measures your ability to operate a vehicle safely and follow instructions from an examiner.
You typically take the written test first. Once you pass it, you can schedule the road test at a later date. Some facilities allow you to take both on the same day if you pass the written portion, but this is not may provide — check with your local driver services office about their scheduling practices.
Where to find the official manual and test information
The Illinois Secretary of State website (cyberdriveillinois.com) is the official source for the Driver's Manual, test scheduling, facility locations, and current fees. You can also visit or call any driver services facility in Illinois to ask questions about the test, request a manual, or schedule your appointment.
The Secretary of State also publishes information about what documents you need to bring, whether you are a first-time applicant, renewing, or testing after a suspension. Having the correct documents on test day prevents delays and ensures your test counts toward your license.
