What driver fitness rules are on the Illinois permit test?

Illinois's driver fitness questions come from its own statutes and the Illinois Secretary of State handbook. QuizLane covers 4 Illinois-specific driver fitness items, drawn from 4 distinct source sections, alongside 10 questions on rules that apply in every state.

How many driver fitness questions are on the Illinois permit test?

Illinois Secretary of State does not publish a per-topic breakdown. The test as a whole has 35 questions and you need 28 correct (80%) to pass, so driver fitness is worth studying alongside every other topic rather than in isolation.

Are these official Illinois DMV driver fitness questions?

No. These are original study questions written against Illinois law and the official handbook, each carrying the section it came from. They are not endorsed by Illinois Secretary of State and are not copies of the real exam.

Do I need an account to practice Illinois driver fitness questions?

No. Practice starts immediately as a guest. An account is optional and only saves your attempt history across devices.

4 questions on Illinois’s own driver fitness rules

These differ from the rules that hold nationally — they are the ones that catch out drivers who studied another state’s handbook.

- AIncreasing your speed
- BDriving with the windows closed
- CFixing your gaze on the centre line

- ANoticing signs sooner
