View All PlansHave you ever wanted to know what the official general knowledge exam is like? Too many applicants fail simply because they weren’t properly prepared. That’s why using the right tools during your learning phase is so important. With perseverance and consistent practice, you’ll gradually improve your knowledge and gain the confidence to walk into the DMV office, ready to succeed on your first try.
Our Maine CDL Class B Practice Test closely reflects the content and format of the official general knowledge exam. It consists of 50 questions based on the Maine Commercial Driver License Manual (Maine CDL Handbook 2025), an official resource published by the Maine DMV. There are multiple answer choices, but only one is correct. Please read every question twice and think before you choose an answer.
Students with auditory memory can significantly boost their learning potential by activating the voice-over function. This feature uses an artificial voice to read the questions and answer choices aloud, making it easier for you to retain information. You can also activate the ambient music to eliminate distractions and maintain focus in busy environments.
All users benefit from unlimited attempts and nonstop browser-based access. Getting started with our practice test is simple. All you need is a compatible device and a stable internet connection. Whether you’re on a laptop at home, a tablet in a coffee shop, or your phone while traveling, you can access this tool anytime, anywhere in the world.
To prevent eye strain and discomfort during longer study sessions, you can adjust the font size to your preference. Use the slider in the test settings menu to enlarge the text until it becomes easier to read. This menu can be accessed by clicking the three dots in the top-right corner of the page.
Commercial driving cannot be learned overnight. It takes several weeks to fully master this subject. Use our Maine CDL Class B Practice Test alongside the official commercial driver license manual to build essential knowledge that will serve you throughout your career.
