Illinois DMV Practice Test 3 (2026)

Speed limits and following distance are tested on every real exam, and this free Illinois DMV practice test covers both. Illinois interstates run up to 70 mph, but the Illinois Rules of the Road is clear that you must always drive to conditions, slowing for rain, traffic, curves, and construction no matter what the posted limit says. This Illinois permit practice test asks how basic speed law works and when a legal speed becomes unsafe. How many questions are on the Illinois permit test? Thirty-five, and you need 80% to pass, so understanding speed rules keeps your score high.

Following distance is the other half of this Illinois Secretary of State practice test. Use the three-second rule: pick a fixed object, and if you reach it before you finish counting three seconds after the car ahead passes it, you are too close. Add more seconds in rain, snow, or fog. Tailgating causes rear-end crashes and shows up often on the Illinois DMV test 2026. This free Illinois permit test practice needs no signup, so retake it until safe speed and following distance feel natural before your official Illinois DMV test.
