FREE Alberta Class 4 Licence Knowledge Exam Practice Test
In Alberta, a Class 4 licence allows you to drive taxis, rideshare vehicles, ambulances, and small buses (up to 24 passengers, including the driver). To obtain a Class 4 licence, applicants must be at least 18, pass a medical exam, submit a completed Driver's Medical Report Form, pass the Alberta Class 4 knowledge exam, and pass a road test specific to Class 4 vehicles. The official written test has 30 multiple-choice questions based on the official Alberta Commercial Driver's Guide. To pass, you must answer at least 25 questions (83%) correctly, which leaves little room for error. Our Alberta Class 4 Licence Knowledge Practice Test has been designed with efficiency in mind. This intuitive tool adds flexibility to your study sessions, allowing you to practice anytime, anywhere in the world. All you need is a compatible device and a stable internet connection. Beginners who are unfamiliar with operating Class 4 vehicles should ignore their scores and focus on increasing their knowledge instead. We provide a detailed explanation for every question, allowing you to learn from your mistakes as soon as they occur. Please note this feedback down in a notebook or notebook app and revisit the material during future practice sessions. Keep track of your progress with the test overview on the left side of the page. This feature updates in real time, giving you insight into your performance. Each question you've gotten right will turn green, while those you've answered wrong are coloured red. You can wipe your current progress and begin a new session at any time by using the “Restart” button. Use it whenever you want to try a different approach and rebuild your confidence after a disappointing attempt. Becoming a safe and responsible driver takes time and effort. As you begin your learning phase, you should avoid rushing through this process and gradually increase your knowledge over the next few weeks. Incorporate this practice test into your study sessions and learn driving theory through repetition. Since you get unlimited attempts and nonstop access, there’s no limit to how often you can study with this intuitive tool.

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 state'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.
Our Premium Membership comes with a Pass Guarantee (30-day access and longer). If you successfully complete all the practice tests for your province/territory, we promise you a passing grade on your official written knowledge test or we'll refund your money. Your most recent completion of all the tests should be not earlier than 30 days before your exam date.
