FREE ICBC Knowledge Test Practice: Class 4 Licence
- Based on 2026 BC commercial driver's licence manual
- Updated for January 2026
- Perfect for first-time and renewal commercial applicants, and those adding endorsements
- Triple-checked for accuracy
In British Columbia, a Class 4 licence provides a wide range of opportunities. You can drive taxis, small buses (up to 24 passengers), and ambulances. To apply, you must be 19 or older and hold a valid class 5 licence. A medical exam is also required, and a criminal record check is conducted for some vehicles. Your Class 4 licence is issued after passing a multiple-choice knowledge exam and a road test. If you are anxious about this process, we’ll help you build the confidence and knowledge to obtain a passing score.
To assist students in their learning phase, the Insurance Corporation of British Columbia (ICBC) publishes the official British Columbia guide for driving commercial vehicles. You should read its contents at least once to learn the various aspects of commercial driving theory. However, there are other tools that are more efficient by enabling active learning. To pass the official exam on your first attempt, we recommend adopting a systematic approach and developing a study routine you can follow consistently.
Our ICBC Class 4 knowledge practice test can significantly boost your learning potential. Each of its questions has multiple answer choices, but only one is correct. This intuitive tool has been designed to closely reflect the content and format of the official exam, giving you valuable insight into the testing experience. Too many students make avoidable mistakes at the ICBC office by rushing. Since we have omitted any timer from this intuitive tool, we recommend you read every question twice before selecting an answer. If you make a mistake, our system automatically provides a detailed explanation of the correct answer. Please note this feedback down in a notebook or notebook app to make it easier to remember later.
With this practice test, you’re not just studying to obtain a passing score; you’re building the foundation of your dream career and developing a lifelong skill. Start today and take the first step towards becoming a safe and responsible driver. With the right tools, even the most complex aspects of commercial driving theory are easier to understand.

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.
