The Wyoming Department of Transportation (DOT) requires all applicants to pass the official combination vehicles knowledge test and meet several other requirements before they can operate tractor-trailers or semi-trucks. This exam consists of 20 multiple-choice questions based on the official Wyoming Commercial Driver License Manual (Wyoming CDL Handbook 2025). This manual includes a section dedicated to combination vehicles (Section 6). A minimum score of 80% is required to pass.
These questions cover topics such as safe driving practices for combination vehicles, pre-trip inspections, and coupling and uncoupling procedures. Knowing how to prevent the jackknife situations that Wyoming’s icy roads can trigger is crucial during winter. That’s why you must fully understand this subject before moving forward in the licensing process.
Our Wyoming CDL Combination Vehicles Practice Tests can significantly boost your learning potential. This particular practice test includes 25 questions with detailed explanations. Please pay attention to the feedback provided after you select an answer. This helpful insight explains the reasoning behind each correct answer, and you should note it in a notebook or notebook app for future reference.
Optimized for multiple devices, this practice test can be accessed on laptops, smartphones, tablets, and desktop computers. You’ll need a stable internet connection since this tool runs in your web browser. If your connection is interrupted during a practice session, you won’t lose your progress. As long as you’re not in private browsing mode (such as Incognito mode in Google Chrome), you can resume from the last question you answered once your connection is restored.
Commercial driving theory is a complex subject, and sometimes reading the official Commercial Driver’s Handbook is not enough. You can check out our Free Wyoming CDL Permit Practice Test, which is specifically designed to make you a better driver. Improve your knowledge one question at a time and build a strong foundation for your driving skills.
Once you’re consistently scoring 90% or higher on our practice tests, it’s a strong indication you’re ready. On exam day, you will walk into the DOT location with confidence, ready to ace your theory exams on your first attempt.
