The ProDriverU Combination Vehicles CDL permit test preparation tools are designed to help you study for the Combination Vehicles written test you will take if you want to get a CDL to drive a Combination Vehicle.
The Combination Vehicles CDL permit knowledge test is for commercial drivers if your vehicle is a “combination” of a truck and a trailer (or trailers). This includes tractor-trailer, double or triple trailers, or straight truck with a trailer).
The ProDriverU tools below contain information you need to learn about combination vehicles. If you want to drive a combination vehicle, you must take a test on this information to get a CDL with the Combination Vehicle Endorsement. These written tests are usually administered at your local DMV office.
In this course you will find two helpful ProDriverU tools. Both are designed to help you learn the CDL concepts by using a “question and answer” format:
Course Content – This is another resource that is in quiz format. Quizzes are broken into individual topics. As you take the quizzes, you will see the correct answer. Use the quizzes to learn important CDL concepts for the topic.
Practice Tests – Practice tests have audio available so you can listen to the questions. You will be asked specific questions that may be on the CDL written test you will take to get your CDL permit or Endorsement. We recommend that you take all tests until you answer most (more than 80%) correct. The tests give you the correct answer so that you can learn as you test.
The ProDriverU test questions are very similar to the questions you will see on the state CDL permit written test.
The following topics are included in Combination Vehicles:
- Driving Combinations
- Combination Vehicle Air Brakes
- Anti-lock Brake Systems
- Coupling and Uncoupling
- Inspecting Combinations
Access to the course is limited to 30 days. You may “buy” the course again if you need more time to complete the course.
