Free IL CDL School Bus Practice Test 2025
If you’re looking to get a School Bus (S) endorsement, you must pass a written knowledge exam that evaluates your understanding of this subject and meet a number of other requirements. Some aspiring school bus drivers find this daunting process more difficult than expected. But with preparation and practice, every challenge can be overcome by those who adopt a systematic approach. We will help you pass the CDL School Bus written test in Illinois so you can fulfill your dream of becoming a school bus driver.
You might already be familiar with the official 2025 CDL manual, but it won’t necessarily help you learn what driving school buses is about. While this manual is an essential piece of the puzzle, it is not enough on its own

To drive yellow (e.g., full-size) school buses, you must also obtain a Passenger Vehicles (P) endorsement. Our free Illinois CDL school bus practice tests cover a wide range of commercial driving topics, including all endorsements.
Illinois is well-known for having one of the most stringent safety programs for school buses. The Illinois Department of Transportation (IDOT) ensures high safety standards through several methods.
Annual inspections are performed for every school bus, and drivers must complete an 8-hour initial classroom training course. Additionally, they must attend annual refresher courses to stay up-to-date with laws and safety practices. The learning process never truly ends, so it is recommended that you continue practicing on our tests periodically to ensure your knowledge stays fresh throughout the year.
