Free OR CDL School Bus Practice Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 OR commercial driver's license manual
- Triple-checked for accuracy
- Updated for March 2025
Oregon is well-known for its diverse landscapes, ranging from coastal cliffs to mountainous regions. Here, school buses play a critical role in safely transporting students across these diverse terrains, ensuring children from both urban and rural areas have access to an education. To become a school bus driver in this state, you must obtain a Commercial Driver’s License (CDL) with a School Bus (S) endorsement and a Passenger Vehicles (P) endorsement. You must also pass the official Air Brakes knowledge test so that your CDL will allow you to operate school buses equipped with air brakes. These requirements ensure that drivers can manage these large vehicles and safely transport students to and from school.
To make this process easier for you, we’ll help you pass the official School Bus knowledge test in Oregon. This test has 20 questions based on the official Oregon CDL Handbook 2025. This manual contains everything you need to know about commercial driving and its endorsements, but most students find the material difficult to study. Fortunately, there are plenty of online resources available for everyone who wants to adopt a smarter approach.
Our free Oregon CDL School Bus practice tests closely reflect the official written exam. Updated for March 2025, these practice tests are designed to help you better understand what this subject is about. Driving a school bus in Oregon involves more than just transporting students. It requires skill, responsibility, and the ability to adapt to the changing road conditions. When you consistently use our practice tests, you naturally develop a better understanding of these concepts.
Passing the official exams shouldn’t be your final goal. The learning process never truly ends. After starting a career as a school bus driver, you’ll be required to periodically attend training sessions. They are supposed to keep your memory fresh and inform you of the latest changes. While our practice tests help build the foundation for this skill, it is your job to keep it sharp over the years.
Even after passing the official written exam and successfully becoming a school bus driver, you can use our practice tests to ensure you don’t forget certain aspects of commercial driving. Since you have unlimited attempts, you can practice as often as you want, limited only by your own schedule.
