View All PlansTo legally operate combination vehicles (such as semi-trucks and tractor-trailers), you must hold a Class A CDL (Commercial Driver’s License). To receive this license, you must pass a 50-question general knowledge exam and a 20-question combination vehicles knowledge test, as well as a skills test in a combination vehicle. During the licensing process, you must also complete ELDT (Entry-Level Driver Training) from a provider listed in FMCSA’s Training Provider Registry (TPR) and pass a medical examination (unless you plan to engage in excepted commerce).
We’ll help you pass the official combination vehicles knowledge test by providing you with access to intuitive tools. Our Free Rhode Island CDL Combination Practice Tests are designed to significantly boost your learning potential. This particular practice test includes 25 multiple-choice questions based on Section 6 (Combination Vehicles) of the official Commercial Driver License Manual (Rhode Island CDL Handbook 2025).
We have recently updated this practice test for December 2025. It includes the latest updates brought by DMV rules or state law, and you will always practice with the latest version. (For the most up-to-date information, you should visit the official DMV website.)
Even experienced truck drivers revisit learning materials to keep their skills sharp. A passing score on your theory exams is not enough to make you a better driver. When you study commercial driving theory, it is crucial to understand each topic. Don’t just memorize the correct answers mechanically. Please pay attention to the detailed explanation provided for each question. This feedback can help you understand the reasoning behind each correct answer so that you can apply the knowledge in real-life driving situations.
You get unlimited attempts and nonstop access to train as often as your schedule allows. On average, it takes several weeks to learn a new subject. If you are unfamiliar with general commercial driving theory, you can check out our Free Rhode Island CDL Permit Practice Test. It is available 24/7, and you can access it on any compatible device.
Before you schedule and take your skills tests, use our practice tests to master commercial driving theory and its various aspects. Keep track of your scores and train until you consistently achieve 90% or higher. Passing your theory exams is your first step toward earning a Class A CDL, and we’ll help you build the knowledge and confidence to succeed.
