Illinois Permit Test FAQs
How many questions are on the real Illinois permit test?
The Illinois written exam contains 35 questions. Fifteen questions cover traffic-sign identification, while the remaining 20 are multiple-choice or true/false questions.
What score do I need to pass?
You must answer at least 80% of the questions correctly. On a 35-question test, that means at least 28 correct answers.
How much does the Illinois knowledge test cost?
The fee for an Illinois Class D instruction permit is $20. This application fee covers up to three attempts to pass each required examination within one year from the date the fee is paid.
Can I take the Illinois permit test online?
No. The official written examination must be completed in person at an Illinois Secretary of State DMV facility that offers written testing. Appointment requirements vary by location, and appointments are required at many of the busiest facilities.
What should I bring to the Illinois DMV office?
Bring acceptable documents proving your written signature, date of birth, Social Security number and Illinois residency, together with the required fee. Applicants under 18 may also need parent or legal-guardian consent and proof of enrollment in or completion of an approved driver-education course.
