ILLINOIS STUDY GUIDE
How to prepare for the Illinois written test
Use the current 2026 Rules of the Road as your main study source. The Secretary of State workbook describes a test structure with separate sign-identification questions and additional rule questions. This original sample is designed to help you review those subjects; it is not a state exam or a guarantee of passing.
Review the teen permit phase
For 15-year-old permit applicants, Illinois lists parent or guardian consent, driver-education enrollment, vision and written tests, and a minimum nine-month permit period.
Know passenger and nighttime limits
Initial license restrictions include nighttime hours and a limit on unrelated passengers under 20 during the first year or until age 18. Local curfews may differ.
Keep your phone put away
Illinois prohibits texting and other electronic communication while driving. Drivers under 19 may not use a cellphone, including hands-free, except for specified emergencies.

- Take the 35-question practice mode, which samples 15 sign questions and 20 other questions.
