To operate LCVs (Longer Combination Vehicles) in Utah, you must hold a valid Class A CDL (Commercial Driver’s License) with a Double/Triple (“T”) endorsement. To qualify, you must be at least 18 for intrastate driving (within Utah) and 21 for interstate driving (across state lines) or hauling hazardous materials. You must also pass a medical examination, pass a vision test, and complete Entry-Level Driver Training (ELDT) from a provider listed in FMCSA’s Training Provider Registry (TPR).
The “T” endorsement can be obtained by passing a -question knowledge test. It is based on the official Commercial Driver License Handbook (Utah CDL Handbook 2026), specifically Section 7 (Doubles and Triples). To achieve a passing score of 80% on your first attempt, you should train with our Utah CDL Double/Triple Trailers Practice Tests. They are available online and can be accessed on any compatible device.
You’re about to take the fourth practice test in this series. Its content and format are similar to those of the official Double/Triple Trailers Knowledge Exam, helping you familiarize yourself with the official testing experience. All questions on this practice test have multiple answer choices, but only one is correct. For your convenience, we have omitted any timer and implemented several features.
Please read each question several times to fully understand what is being asked. If you encounter a difficult question, our automated assistant can provide you with hints. These hints will nudge you in the right direction without revealing the correct answers. It’s easier to understand this subject when you receive personalized help, so don’t hesitate to ask for it during your training sessions.
