FREE YT General Knowledge Test 1 2025
Welcome to the first of our Yukon General Knowledge Practice Tests. This intuitive tool is up to date as of June 2025, so you will always practise with the latest version. All 25 questions have multiple answer choices, but only one is correct. The official Driving Commercial Vehicles manual is a guide for professional drivers and includes complete information on air brakes and other aspects of commercial driving theory. Please read its contents at least once, as all the multiple-choice questions on the official Yukon Commercial Vehicle Knowledge Test are based on this manual.
Commercial driving is a lifelong skill that cannot be learned overnight. As you begin your learning phase, it is crucial to adopt an unhurried, deliberate approach. During this time, you should develop a study routine and follow it on a daily basis. Include the official manual and our practice tests in this routine, and see your confidence and knowledge gradually improve with time. You can use several features of our testing system to enhance your learning potential by customizing your testing experience. Access them from the “Test settings” menu on the left side of the page. From here, you can enable the voice-over function, which uses an artificial voice to read the questions and answer choices aloud. This particular feature is useful for students with auditory memory and those studying in busy environments where distractions are more common.
Our automated assistant will be present during your training sessions. It can provide hints that nudge you in the right direction without revealing the correct answer. Initiate a conversation whenever you wish to receive further explanations and real-life examples that help you better understand commercial driving theory.
Since you get unlimited attempts and non-stop access to our practice tests, there’s no limit to how often you can study. For best results, we recommend keeping track of your scores and taking the official general knowledge exam only after you consistently achieve passing scores on our practice tests. The roads of Yukon can be harsh and unforgiving, but as a professional driver, you’ll face every challenge with confidence and safely deliver cargo to the most remote destinations.
