View All PlansIn Vermont, the Department of Motor Vehicles (DMV) oversees the licensing process and requires all aspiring commercial drivers to pass several exams. You must be at least 18 to apply for a Class A CDL (Commercial Driver’s License), but you won’t be able to transport passengers, carry hazardous materials, or drive across state lines before you turn 21.
The official general knowledge test is your first theory exam. You must answer all 50 questions and score 80% or higher to pass, leaving little room for error. All questions are based on the official Commercial Driver’s Manual (Vermont CDL Handbook 2025), which you should read multiple times during your learning phase. Our Free Vermont CDL Permit Practice Test will help you prepare for this exam, so you can easily achieve a passing score on your first attempt.
All of our practice tests are available online and can be accessed in a browser, so you won’t need any sophisticated software. The simple user interface makes it easy for anyone to take our practice tests, even those who are unskilled with computers. Keep in mind that you will need a stable internet connection at all times.
If you are interested in driving combination vehicles (such as tractor-trailers and 18-wheelers), you must also pass the official combination vehicles knowledge exam and a skills test in a combination vehicle. Since most combination trucks in Vermont are equipped with air brakes, we recommend passing the official air brakes knowledge test as well. You must pass this exam to have the “L” restriction removed from your CDL. The combination vehicle you use for your CDL skills test must also be equipped with air brakes.
This Free Vermont CDL Combination Practice Test closely reflects the content and format of the official combination vehicles knowledge test. All 25 questions are based on Section 6 (Combination Vehicles) of the official commercial driver’s manual. Please answer all questions at your own pace and avoid rushing. Improve your knowledge gradually and keep track of your scores. Train daily, and on exam day, you’ll ace the official combination vehicles knowledge exam on your first attempt.
