If you’re in Wisconsin, this free CDL school bus practice test is for you!
Since the United States is a car-reliant country averaging roughly two vehicles per household, most of its residents use a car to get around. Whether commuting to work, adventuring on road trips or simply running errands like grocery shopping, the first choice tends to be a personal vehicle. But what about students who are too young to obtain a driver’s license? What if their parents don’t have one either?
Introduced in the 1920s, school buses are specialized vehicles designed to transport students to and from school. They’re easily recognizable due to their bright yellow color, chosen for increased visibility in various weather conditions. These buses have several unique features, such as flashing lights, high seat backs, and stop arms. Built to meet strict safety standards, they can only be operated by trained professionals.
To become a school bus driver in Wisconsin, you’ll need a School Bus (S) Endorsement on your Commercial Driver’s License (CDL). If the school bus is designed to carry 16 or more occupants, you’ll also need a Passenger Vehicles (P) Endorsement. Additionally, your CDL must authorize you to operate vehicles with air brakes if the school bus you intend to drive is equipped with air brakes. This restriction is removed by passing an additional written exam.
The official 2025 CDL manual explains these concepts well, but it’s not enough on its own. Our CDL School Bus practice tests closely reflect the official exam, allowing you to become familiar with its content and format. Consisting of 21 questions, these practice tests can be used both as an educational tool and a way of evaluating your knowledge. This CDL school bus practice test makes it easy to pass in Wisconsin!
Since there is no time limit, students can take as long as they need to select an answer. Immediate feedback and a detailed explanation of the correct answer are provided after each question, so you don’t have to wait until the end of the test to know your score. You should practice regularly and only take the official written exam once you consistently obtain a passing score on our practice tests.

At Driving-Tests.org, we understand the importance of reliable and accurate practice tests to help you prepare for your DMV exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.

Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
