View All PlansImagine you are pulling a 53-foot refrigerated trailer loaded with produce from Salt Lake City to Las Vegas. You approach a steep downgrade, and you need to know exactly how your air brakes will respond, how to prevent trailer swing, and what your stopping distance is. In Utah, the Driver License Division (DMV) requires all aspiring commercial drivers to master the various aspects of commercial driving theory before they can obtain their Commercial Driver’s License (CDL). This subject is thoroughly described in the official Utah Commercial Driver License Handbook (Utah CDL Handbook 2025). You should read this manual multiple times during your learning phase, especially the sections you are most interested in.
To drive combination vehicles (such as semi-trucks and tractor-trailers), you must pass the official combination vehicles knowledge exam and your CDL skills tests in a combination vehicle. All 20 questions on the theory exam are based on Section 6 (Combination Vehicles) of the official Commercial Driver License Handbook. They cover pre-trip inspections for combination vehicles, weight distribution, cargo securement, and coupling and uncoupling procedures. A minimum score of 80% is required to pass, leaving little room for error.
Our Utah CDL Combination Vehicles Practice Tests are designed to help you master this subject. This particular practice test closely reflects the content and format of the official combination vehicles knowledge exam. It is up to date as of November 2025 to reflect the latest updates brought by DMV rules or state law. Each question includes a detailed explanation. Please pay attention to this feedback as it helps you learn from your mistakes.
You get unlimited attempts and nonstop access to our practice tests. We recommend taking this practice test until you can consistently score 90% or higher. Your knowledge will naturally improve with more practice. However, it is crucial to understand the reasoning behind each correct answer. Don’t just memorize answers mechanically. Commercial driving involves great responsibility, and only professional drivers find success in this field.
Start your learning phase today and use our practice tests to boost your learning potential. Our Free Utah CDL Permit Practice Test can help you ace the official general knowledge exam on your first attempt. Check it out and incorporate it into your daily study routine. Consistency and perseverance are keys to success when studying a new subject, so you should stick to your study routine and stay committed.
