FREE Quebec Class 4 Licence Test
In Quebec, the Class 4 licence is divided into three different subclasses. A Class 4A licence allows you to drive emergency vehicles, and a Class 4B lets you drive small buses with a seating capacity of 24 or fewer passengers. To become a taxi driver, you'll need a Class 4C licence, which allows you to drive taxis.To obtain a Class 4 licence in Quebec, you must pass a knowledge exam and meet several other requirements. All 30 questions are based on the official Quebec commercial driver’s handbook, the main study resource for aspiring commercial drivers. A score of 80% or higher is required to pass, and you must answer all questions before the timer runs out. Students struggling with test anxiety are more likely to make mistakes. However, you can significantly increase your chances of obtaining a passing score by beginning your learning phase several weeks in advance.During this time, you should use the most efficient tools available. Our Quebec Class 4 Licence practice test has been designed to closely reflect the content and format of the official written knowledge test. When you regularly train with this tool, you'll know what to expect at the SAAQ office on exam day. You get unlimited attempts and nonstop access to this intuitive tool so that you can increase your knowledge through repetition. For your convenience, we have omitted any timer from this practice test. Please take your time and avoid rushing through the questions.If you make a mistake, we will point it out as soon as it occurs. A detailed explanation of the correct answer will help you understand why your choice was wrong. You should note this feedback in a notebook or notebook app and revisit the material during future practice sessions. Obtaining a Class 4 licence may be difficult for a beginner unfamiliar with commercial vehicles, but we'll make it easier for you to understand this subject. Our helpful automated assistant can provide personalized answers to your individual questions, making it a great addition to your study sessions. Additionally, you can request hints whenever you get stuck on a difficult question.

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.
