View All PlansAre you looking for an efficient tool to help you study for your upcoming knowledge tests? Our Connecticut CDL Combination Vehicles Practice Tests are the solution to your study needs. The practice test that you’re about to take closely mirrors the official combination vehicles knowledge test. 25 multiple-choice questions are included, and they are all based on Section 6 (Combination Vehicles) of the official Commercial Driver’s License Manual (Connecticut CDL Handbook 2025). You must answer 20 (80%) of them correctly to pass.
When you’re behind the wheel of an 18-wheeler, there’s no room for error. You must be prepared to handle the challenges you may face on the road, and that’s what the Commercial Driver’s License Manual teaches you. As you begin your learning phase, we recommend reading its contents multiple times. You will study emergency procedures, commercial driving regulations, air brake systems, and coupling and uncoupling procedures. Before exam day, you can use our Free Connecticut CDL Permit Practice Test to strengthen your knowledge of this subject.
With unlimited attempts and nonstop browser-based access, you can train with our practice tests anytime, anywhere in the world. Run a quick session while waiting in line at the grocery store, during a football halftime, or even while traveling. Please keep in mind that you will need a stable internet connection at all times.
Although this practice test takes only 10 minutes to complete, you should finish each practice session at your own pace. There’s no timer to pressure you. Read every question twice and carefully consider each answer choice before choosing the one you consider correct. You can also initiate a conversation with “Officer Frank,” your automated assistant. He can give you hints, real-life examples, and personalized answers to your individual questions. “Officer Frank” will be present during your training sessions, so don’t hesitate to ask for help!
On exam day, you’ll need more than luck to pass your theory exams. Train consistently with our practice tests, and your knowledge will naturally improve over time. Within a few weeks, you’ll learn everything you need to know to achieve a passing score on your first attempt.
