Welcome to our Maine CDL Combination Vehicles Practice Test, one of several we offer. Consisting of 25 multiple-choice questions, this intuitive tool closely reflects the content and format of the official combination vehicles knowledge exam. You must answer all questions and score 80% or higher to pass. Except for our exam simulators, our practice tests are not timed. You can finish each training session at your own pace, taking as long as you need to read and answer every question.
The official Maine Commercial Driver License Manual (Maine CDL Handbook 2025) is a comprehensive resource published by the Department of the Secretary of State (DMV). This handbook describes the various aspects of commercial driving theory in detail, including pre-trip inspections and safe driving practices. We recommend reading this manual multiple times during your learning phase. To boost your learning potential, you can use this resource alongside our Free Maine CDL Permit Practice Test.
Your personal Challenge Bank™ can help you identify areas that need improvement and learn from your mistakes. This section automatically stores every question you get wrong so you can practice with them later. We recommend reviewing these questions at the end of your study sessions, and you can even note their explanations in a notebook or notebook app. Premium users can manually add any question to their Challenge Bank. Please keep in mind that questions will remain in your Challenge Bank until you answer them correctly.
