ON Commercial General Knowledge Road Signs
- Based on 2025 ON commercial driver's licence manual
- Updated for September 2025
- Perfect for first-time and renewal commercial applicants, and those adding endorsements
- Triple-checked for accuracy
Did you know that Ontario’s Queen Elizabeth Way is the only major highway in the province that doesn’t have a posted highway number? Instead, its signs feature the letters “QEW” in blue on a yellow background. As a licensed driver, you must be able to recognize road signs and follow their indications at all times. The official Ministry of Transportation (MTO) Truck Handbook describes the various aspects of commercial driving theory, including traffic signs, safe driving practices, and pre-trip inspections.
Our Ontario Commercial General Knowledge Road Signs Practice Test consists of multiple-choice questions based on the traffic signs section of the official MTO Truck Handbook. To pass, you must score 80% or higher. If you make a mistake, we will provide immediate feedback that helps you understand why your choice was wrong. Pay attention to the detailed explanation and note it down in a notebook or notebook app for future reference.
During your learning phase, it is crucial to avoid rushing. For this reason, we have omitted any timer from this practice test. Take as long as you need to analyze each question, inspect the image of the road sign, and consider the answer choices. If you encounter an unfamiliar sign, you can request help from our automated assistant. It can provide hints that nudge you in the right direction without revealing the correct answer. When you receive personalized help, you can study commercial driving theory efficiently.
All users get unlimited attempts and nonstop access to this intuitive tool. You don’t need advanced computer skills to control this practice test. If you fail, you can begin a new session right away. However, you should check your personal Challenge Bank™ first, as it includes detailed explanations for all the questions you got wrong during your previous attempts. Questions in the Challenge Bank will remain there until you answer them correctly.
Your dream career is within reach, and with the right tools, you’ll build the knowledge and confidence necessary to pass the official written knowledge test.

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.
