FREE Ontario Class B (Bus) Commercial Licence Practice Test 1
- Based on 2025 ON commercial driver's licence manual
- Updated for August 2025
- Perfect for first-time and renewal commercial applicants, and those adding endorsements
- Triple-checked for accuracy
Bus drivers are entrusted to safely transport passengers to their destinations. This trust is based on the skills they have acquired through extensive training. If you want to drive a school bus, you’ll need to meet several requirements, including passing the Class B Commercial Licence Knowledge Test to obtain a commercial learner’s licence. The official knowledge test is an opportunity to demonstrate you know how to keep passengers safe. However, you should make sure you are ready for the challenges of the official knowledge test before asking Attridge for the keys to one of their buses.
Our Ontario Class B Licence Practice Test 1 will prepare you to answer questions on passenger safety regulations typically seen on the official knowledge test. The practice test includes multiple-choice questions to test your driving skills. You will get an accurate evaluation of your skill level that points out areas for improvement. Using the practice test, you’ll be able to more efficiently budget your study time to concentrate on the topics you don’t completely understand. Whether it’s emergency procedures, medical reporting, or any other topic you need to study, the practice test will rapidly increase your knowledge base. You will become more confident in your skills and more likely to pass the official knowledge test on your first try.
Compared with other on-line resources, this Ontario Class B Written Practice Test 1 offers the most comprehensive instruction on keeping passengers safe. It is based on the most recent Ontario Official Ministry of Transportation (MTO) Bus Handbook. The practice test goes the extra mile to provide you with an optimal learning experience to support your knowledge base. Other on-line resources, such as study guides, limit your training to memorizing the answers to the questions. If you want to meet the requirement of correctly answering 80% of the official knowledge test questions, a little extra preparation would be helpful. The practice test is interactive and keeps you focused and engaged using randomly selected questions. If you submit an incorrect answer, the practice test will provide a detailed explanation of the correct one. You will gain insight into the logic that supports the answer and apply it to your driving skills. The practice test will equip you with the skills and confidence to safely transport passengers and find greater job satisfaction.

At Tests.ca, we understand the importance of reliable and accurate practice tests to help you prepare for your driver's knowledge 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 Driving Handbooks:
Every question we develop is based on the most recent version of each province's official driving manual. Our team regularly monitors each province's official 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 provincial government manuals. Additionally, we update the free electronic copy of the province's driver's license manuals on our site, typically within a few days after the government 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 driver's knowledge exam.
