Everything you need to pass the Illinois written knowledge test — exam format, passing score, permit requirements and the local rules examiners focus on.
Important Illinois rules
Scott's Law
Illinois' Move Over law carries some of the steepest penalties in the country for failing to yield to stopped emergency vehicles.
Winter driving
Black ice and lake-effect snow are common; braking distances can quadruple on packed snow.
Nine-month permit period
Drivers under 18 must hold the instruction permit for at least nine months with 50 hours of supervised practice.
Zero tolerance
Any trace of alcohol for a driver under 21 results in suspension on a first offense.
- 15 with driver education enrollment
- 35 questions — road rules and road signs
- Passing score 80%
How to study for the Illinois exam
- Illinois emphasizes Scott's Law and school-bus rules on the written exam.
- Practice winter-condition questions — they are unusually common.
- Confirm your documentation early; Illinois enforces strict identity requirements.
