What the Illinois written test covers and how it's scored
The Illinois written driving test has 35 questions, and you need to answer at least 28 correctly to pass — that's 80 percent. The test covers road signs, right-of-way rules, speed limits, parking laws, and safe driving practices. You'll see real Illinois road signs and scenarios you might encounter on an actual road.
The test is offered in English and several other languages. You take it on a computer at a Secretary of State facility, and you get your score when ready. If you fail, you can retake it the same day, though you'll need to pay the test fee again.
The written test is separate from the road test. You must pass the written test before you can schedule the driving portion, so this is your first gate.

Where to find the official Illinois study materials
The Secretary of State publishes the Rules of the Road, a free guide that covers everything on the written test. You can read it as a PDF from the Illinois Secretary of State website or pick up a printed copy at any Driver Services facility. This guide is the most direct way to prepare because the test questions come directly from the material in it.
The guide includes sections on traffic signs and their meanings, right-of-way rules, speed limits, parking, lane changes, and what to do at traffic lights and stop signs. It also covers rules for sharing the road with pedestrians, bicycles, and large trucks. Read through it at least once before you test.
The Secretary of State website also lists the test locations and hours for Driver Services facilities near you. You'll need to know where your nearest facility is and whether it requires an appointment or accepts walk-ins, as this varies by location.
How to register and schedule your test appointment
In Illinois, you do not need to schedule the written test in advance at most locations — you can walk in during business hours and take it the same day. However, some Driver Services facilities do require appointments, so check the Secretary of State website for your specific location before you go.
Bring your current ID, proof of residency (such as a utility bill or lease), and your Social Security number. If you're under 18, you'll also need a parent or guardian present. The test fee is currently $10, though you should confirm the current amount when you call or visit the facility.
If you fail the test, you can retake it when ready by paying the fee again. There is no waiting period between attempts on the same day, so you can study the material you missed and try again right away.
What to expect during the test itself
You'll sit at a computer terminal in a quiet testing area. The test is multiple choice — each question shows you a scenario or a sign, and you select the correct answer from four options. You have time to review your answers before you submit, so take your time and don't rush through.
The questions are not in any particular order of difficulty. You might see a sign recognition question, then a right-of-way question, then a parking rule question. The computer will not tell you which answers are wrong until after you finish and submit the entire test.
Once you submit, you'll see your score when ready on the screen. If you passed, you'll receive a printed score report that you'll need to bring to your road test appointment. If you failed, you can decide whether to retake it that day or come back another time.
Common mistakes people make on the Illinois test
The biggest mistake is not reading the Rules of the Road before testing. People often assume they know the rules from driving experience or from other states, but Illinois has specific rules about things like school bus passing, railroad crossing procedures, and right-of-way at four-way stops. The test asks about these specific rules, not general driving sense.
Another common error is misunderstanding right-of-way at intersections. Many people get confused about who has the right of way when two cars arrive at a stop sign at the same time, or what to do when a traffic light is broken. The Rules of the Road explains these situations clearly, and several test questions will cover them.
People also sometimes confuse speed limit rules. Illinois has different speed limits for residential areas, school zones, and highways, and the test includes questions about when each applies. Reading the specific section on speed limits in the study guide will help you avoid these mistakes.
What happens after you pass the written test
Once you pass, you'll receive a score report. Keep this document — you'll need to bring it to your road test appointment. The written test score is valid for a set period, so check with the Secretary of State about how long your passing score remains good before you must take the road test.
You then schedule your road test with a Driver Services facility. The road test is where an examiner watches you drive and evaluates your ability to control the vehicle, follow traffic laws, and respond to road conditions. The written test and road test are separate events, and you must pass both to get your license.
If you're under 18, Illinois has additional requirements under the Graduated Driver License (GDL) program, including a learner's permit period and restrictions on when and where you can drive. The written test is the same for all ages, but the licensing timeline is different for minors.
Retaking the test if you don't pass on your first try
If you score below 28 out of 35, you did not pass. You can retake the test when ready at the same facility by paying the fee again. Before you retake it, review the Rules of the Road, focusing on the topics you found confusing. Many people pass on their second attempt after spending time on the specific weak areas.
There is no limit to how many times you can retake the written test in Illinois. However, each attempt costs the test fee, so studying thoroughly before your first attempt saves you money. If you keep failing after multiple attempts, consider asking a friend or family member to quiz you on the material, or visit a Driver Services facility to ask staff which topics are giving you the most trouble.
Frequently Asked Questions
Can I take the test in a language other than English?
Yes. Illinois offers the written test in English, Spanish, Polish, and several other languages. When you arrive at the Driver Services facility, tell the staff which language you need, and they will set up the test in that language. The content and passing score are the same regardless of language.
What if I fail the written test — do I have to wait before retaking it?
No. You can retake the test the same day you fail it. You'll need to pay the test fee again, but there is no waiting period. Many people use the time between attempts to review the Rules of the Road and focus on the topics they found hardest.
How long is the written test score valid before I have to take the road test?
The written test score is valid for a specific period set by Illinois, though the exact length varies. Check the Secretary of State website or ask at your Driver Services facility when you pass, so you know the important date for scheduling your road test. If your score expires, you'll need to retake the written test.
Do I need an appointment to take the written test in Illinois?
Most Driver Services facilities accept walk-ins for the written test, but some locations require appointments. Check the Secretary of State website for your nearest facility to see whether you need to book ahead. Calling the facility directly is the fastest way to confirm.
What documents do I need to bring to take the written test?
Bring a current ID, proof of residency (such as a utility bill or lease), and your Social Security number. If you're under 18, a parent or guardian must be present. Bring the test fee in cash or card, depending on what the facility accepts.
