View All PlansIf you’ve just started studying commercial driving theory, you’re probably familiar with the official Commercial Driver License Handbook (Utah CDL Handbook 2025). This resource describes important topics you should know.
Your knowledge of commercial driving regulations, pre-trip inspections, and safe driving practices will be evaluated through 50 multiple-choice questions on the official general knowledge test. You must score 80% or higher to pass, leaving little room for error. Our Free Utah CDL Permit Practice Test can help you achieve a passing score on your first attempt. You can use it anytime, anywhere in the world as long as you have a compatible device with a stable internet connection.
If you are interested in driving combination vehicles, you must also pass the official combination vehicles knowledge test and a skills test in a combination vehicle. The official commercial driver license handbook includes a section that describes this subject in detail (Section 6). You should study it carefully, and when you’re ready, you can use our Free Utah CDL Combination Practice Tests to evaluate your knowledge. This particular practice test has 25 questions, which you can answer at your own pace. Your session will not be timed, so you can take as long as you need to answer all the questions.
A detailed explanation of the correct answer will be provided for each question. Please read this explanation and note it in a notebook or notebook app before you proceed to the next question. If you make a mistake, we will automatically add the missed question to your personal Challenge Bank™. This section provides helpful insights that can significantly boost your learning potential. Visit this section regularly to identify areas that need improvement and learn from your mistakes.
Commercial driving theory is a complex subject that takes weeks to master. Use our practice tests alongside the official commercial driver license handbook to study efficiently. Consistency, patience, and perseverance are the keys to success.
