The Illinois written test covers road signs, traffic laws, and safe driving practices

The Illinois Secretary of State administers a written test as part of the driver license process. The test has 35 questions, and you must answer at least 28 correctly to pass. Questions come from the Illinois Driver's Manual and cover traffic signs, right-of-way rules, speed limits, parking laws, and what to do in emergencies. You take the test at a Driver Services facility, and results are available when ready after you finish.

The test is multiple choice with four answer options per question. You answer on a computer terminal at the facility — there is no paper version. The test is offered in English and several other languages, including Spanish, Polish, and Mandarin Chinese. You can request an interpreter or reader if you need one, though you must arrange this before your test date by contacting the facility where you plan to test.

What the Illinois Driver's Manual covers

The Illinois Driver's Manual is the source document for every question on the written test. The manual is divided into sections on traffic signs and markings, right-of-way and turning rules, speed limits and safe speeds, parking and stopping, seat belts and child safety seats, and what to do if you are stopped by police or involved in a crash.

The manual also covers impaired driving laws, distracted driving rules, and the consequences of traffic violations. A section on sharing the road addresses pedestrians, bicyclists, and motorcyclists. The manual is updated periodically when Illinois law changes, so if you studied an old version, some answers may have shifted. You can read the current manual as a PDF from the Illinois Secretary of State website, or pick up a printed copy at any Driver Services facility at no cost.

How to prepare for the test

Most people study the Illinois Driver's Manual for a few days to a week before their test date. Read through each section and pay close attention to the traffic signs — the test includes several questions showing sign images and asking what they mean. The manual includes practice questions at the end of each chapter, and working through these gives you a sense of how test questions are worded.

Some people use online practice tests, which are available through third-party websites. These are not official Illinois materials, but they follow the same format and topics as the real test. If you use a practice test, verify that it covers current Illinois law — older versions may include outdated information. Focus on areas where you scored lowest on practice tests, rather than re-reading sections you already know well.

What happens on test day

Arrive at your Driver Services facility at least 15 minutes before your scheduled appointment. Bring a valid form of ID — a passport, military ID, or state ID card all work — and proof of your current address, such as a utility bill or lease. The staff will verify your identity and check that you are not already licensed in another state.

You will be taken to a computer terminal in a quiet area. The test administrator will explain how to use the terminal and answer any questions about the format. Once you begin, you have no time limit per question, though the entire test usually takes 20 to 30 minutes. You can review your answers before you submit. After you submit, the computer when ready shows your score and whether you passed.

What to do if you fail

If you do not reach 28 correct answers, you fail the test. There is no waiting period — you can return to the same facility or a different one on another day and test again. You will pay the test fee again, which varies by facility but is typically around $10 to $15. Some people fail because they did not study the manual thoroughly; others because they misread questions or second-guessed correct answers.

If you fail, ask the staff whether they can tell you which topics gave you trouble. Not all facilities provide this feedback, but some do. Return to the manual and focus on those sections before your next attempt. If you have failed twice, consider studying with someone else or using a practice test to identify gaps in your knowledge.

Retesting and moving forward

You can retake the written test as many times as you need. There is no limit on the number of attempts, and no waiting period between tests. Once you pass, your passing score is valid for a set period — usually 12 months — while you complete the other steps toward a license, such as the vision test and road test.

If your passing score expires before you complete the road test, you will need to retake the written test. This happens most often when people pass the written test but then delay scheduling their road test. Check with your local Driver Services facility about how long your passing score remains valid in your area.

Test accommodations and language options

If you have a disability that affects your ability to read or understand the test, you can request accommodations. Common accommodations include a reader who reads questions aloud, extra time to answer, or a screen magnifier for people with low vision. You must request accommodations before your test date — ideally when you schedule your appointment — by contacting the Driver Services facility directly.

The test is available in English, Spanish, Polish, Mandarin Chinese, and several other languages. If you need the test in a language not listed, contact your local facility to ask whether they can arrange it. Some facilities offer more language options than others, so if your preferred language is not available at your nearest location, you may be able to travel to a larger facility that offers it.

Frequently Asked Questions

Can I use the Illinois Driver's Manual on my phone during the test?

No. You cannot bring any materials into the testing area, including phones, books, or notes. The test is closed-book, and the facility staff will ask you to leave personal items in a locker or with a staff member before you enter the testing area.

What if I do not speak English well?

The test is available in multiple languages. Contact your Driver Services facility when you schedule your appointment and tell them which language you need. If your language is not available at that location, ask whether another facility nearby offers it, or whether they can arrange an interpreter.

Do I have to pass the written test before I take the road test?

Yes. You must pass the written test before you can schedule a road test. The written test comes first in the process. Once you pass, you can move on to the vision test and then the road test.

How long does the written test take?

Most people finish in 20 to 30 minutes. There is no time limit per question or for the entire test, so you can take as long as you need. You can review your answers before you submit them.

What if I pass the written test but then move to another state?

Your passing score is valid only in Illinois. If you move before you complete the road test, you will need to start the process over in your new state. Each state has its own written test and licensing requirements.
