Illinois Permit Test: What's on the Written Exam and How Many Tries
What is on the Illinois written test, and how many times can I take it?
Under the Illinois Rules of the Road, the written exam asks you to identify traffic signs, signals and pavement markings, and to answer multiple-choice and true-or-false questions on traffic laws, safety rules, crash prevention and vehicle equipment. One application fee covers a limited number of attempts for each exam, so ask the Secretary of State (SOS) how many tries you have. If you cheat, you fail and must wait before you can retest.
Where these Illinois test rules come from
The exam content, the attempt limit, the cheating rule, the oral exam and the vision checks come from the 2025 edition of the Illinois Rules of the Road, the official handbook of the Illinois Secretary of State (SOS). The saved copy is from 2025, so this guide does not give its exact limits and waiting times. Check the current handbook or ask the SOS. The 8-year rule and the renewal rules come from the SOS drivers FAQ and the SOS driver's license page. The language rule and the expired-license rule come from 625 ILCS 5/6-109 of the Illinois Vehicle Code, and the permit steps from the SOS Graduated Driver Licensing (GDL) page. This guide is current as of 2026. Confirm the rules with the Illinois Secretary of State (ilsos.gov) before you drive.
What does the Illinois written exam ask?
The basic written exam asks you to do three things. You identify traffic signs by shape, color or symbol. You identify signals and pavement markings. You answer multiple-choice and true-or-false questions about traffic laws, safety rules, crash prevention and vehicle equipment.
State law also requires questions in the exam's question pool on safe driving near bicycles and on what to do when you approach a stationary emergency vehicle. The Rules of the Road has the information you need for the test on traffic laws and signs. Motorcycle, truck and bus exams are different, so use the manual for that vehicle.

How many times can I take the Illinois permit test?
The number of tries is limited. The 2025 Illinois Rules of the Road links the attempts for each exam to the date you paid your application fee, not to your first try, so a late first try leaves less time for the other attempts. The saved handbook is from 2025, so ask the SOS for the current number of attempts and the time limit before you start. The free practice question on exam attempts after one application tests this rule.
Do I take the written test for a permit?
Yes. A vision screening and a written test are required to get or renew any Illinois instruction permit, and you must pass the exams for the license class you want. At age 15, you also need parent or guardian consent and enrollment in an approved driver education course. At 17 years and 3 months or older, you can apply without a driver education course. The guide to getting an Illinois instruction permit has the full steps.
What happens if you cheat on the test
- The SOS warns an applicant who does something that could look suspicious during the written exam, such as having an open book in view or looking around.
- An applicant found cheating fails the exam and must wait before a retake.
- Taking any part of the exam for another person is a crime. It carries a fine and a mandatory jail term.
- The SOS can deny a license or permit to a person who tries to bribe or influence an SOS employee.
Can I take the Illinois written test orally or in Spanish?
Yes, in some cases. You can ask for an oral exam for the written test in person at an SOS driver's license facility. Ask the facility on which days it gives oral exams. The service is for applicants who may have a language barrier or a reading or learning disability. State law says written and verbal exams may be given in Spanish and, at the SOS's discretion, in other languages, on request. English words on the pictures of road signs stay in English.
When do Illinois drivers take the written test again?
Illinois vision standard for the permit and license
Every permit applicant also has a vision screening. The screening checks your visual acuity and your peripheral vision, with or without corrective lenses. Under the 2025 handbook, lower acuity can limit you to daylight driving. A license applicant can instead submit a Vision Specialist Report from a licensed optometrist, ophthalmologist or physician. The saved handbook is from 2025, so ask the SOS for the current limits and how recent the report must be. At renewal, everyone has a vision screening, except with online renewal.

Illinois written test: common questions
Where can I take the Illinois written test?
Take it at an SOS driver's license facility, which the SOS also calls a DMV or driver services facility. Express facilities do not offer written testing, and they do not process out-of-state transfers. Check the facility type before you go, so that you do not lose a trip.
Can I use my phone during the Illinois written test?
No. The SOS treats checking a cellphone or other wireless device during the exam as an act that could look suspicious, and it warns the applicant. An applicant found cheating fails the exam and must wait before a retake. Put your phone away before the exam starts.
How long are Illinois written test results valid?
For an instruction permit, your vision and written test results stay valid until the permit expires, and the permit is valid for 24 months. If you are 15 to 17, you must hold the permit for at least 9 months before you can get a driver's license.
Do I retake the test if my Illinois license expired?
Expect an exam if your license or permit has been expired for more than one year. State law requires the SOS to examine any applicant who renews after that time. The exam tests your eyesight, your ability to read official traffic control devices, and your knowledge of safe driving and Illinois traffic laws.
