View All PlansDid you know that in Connecticut, commercial drivers must perform a pre-trip inspection of their vehicle at the beginning of their shift? Federal and state laws mandate pre-trip inspections to ensure commercial vehicles are safe and in proper working condition before they go on the road. As you begin your learning phase, it is crucial to develop good habits that will serve you throughout your career. You can find more information on pre-trip inspections and other aspects of commercial driving theory in the official Connecticut Commercial Driver’s License Manual (Connecticut CDL Handbook 2025). Read this manual multiple times, and when you’re ready, you can use our practice tests to evaluate your knowledge.
Our Connecticut CDL Class B Practice Test closely reflects the content and format of the official general knowledge test, helping you get an idea of what to expect on exam day. It consists of 50 multiple-choice questions that will evaluate your knowledge of safe driving practices, air brake systems, and emergency situations. You get unlimited attempts and nonstop access to train as often as your schedule allows. Run a quick session while the dinner cooks, during football halftime, or at the end of a busy day.
Customize your testing experience with the test settings menu, which can be opened by clicking the three dots in the top-right corner of the page. From there, you can toggle features like voice-over and ambient music. For added flexibility, you can also take this practice test using only your keyboard. Use the “Shift + ?” key combination to display a list of available shortcuts.
A detailed explanation of the correct answer is provided for each question. You can use this feedback to strengthen your knowledge and learn from your mistakes. For future reference, we recommend noting it in a notebook or notebook app. This way, you can understand the reasoning behind each correct answer instead of memorizing them mechanically.
Commercial driving theory is a complex subject that cannot be mastered overnight. It takes weeks of consistent practice to become an expert in this field. Our Connecticut CDL Class B Practice Test can help you study efficiently, but you must practice with it regularly.
