View All PlansWelcome to our North Dakota CDL Class B Practice Test! Available 24/7, this intuitive tool can help you master commercial driving theory and prepare for your dream career. All you need to access it is a compatible device and a stable internet connection. It closely reflects the content and format of the official general knowledge exam, which you must pass before you can get a Commercial Learner’s Permit (CLP). All 50 questions are based on the official North Dakota Commercial Driver License Manual (North Dakota CDL Handbook 2025), which you should read multiple times during your learning phase.
Unlike the official general knowledge exam, this practice test is not timed. Take as much time as you need before you select an answer. Read every question twice and consider all answer choices carefully. If you get stuck on a difficult question, you can ask “Officer Frank” for assistance. This AI coach can provide hints, real-life examples, and helpful insights. “Officer Frank” will be present during all of your training sessions, so don’t be afraid to ask him for help!
You get unlimited attempts to train as often as your schedule allows. If you fail, you can begin a new practice session straight away. However, we recommend visiting your personal Challenge Bank™ first. This section stores every question you get wrong and provides detailed explanations that help you learn from your mistakes. You can practice with these questions and improve your knowledge through active learning. Questions in your Challenge Bank will remain there until you answer them correctly.
Commercial driving theory is a complex subject that cannot be mastered overnight. It takes time and effort to build the foundation for this career path, but it will pay off in the long run as you receive better job opportunities and gain confidence on the road. Our North Dakota CDL Class B Practice Test can help you achieve a passing score on your first attempt, but earning a CDL is only the beginning. As you advance in your career, it’s important to revisit learning resources to refresh your knowledge and stay updated on the changing regulations.
