Are you ready to earn your double and triple trailers endorsement? Our Free Montana CDL Double/Triple Trailers Practice Test will tell if you are ready or if there are areas you need to study more. The double/triple trailers endorsement test assesses your knowledge about driving safely with double and triple trailers. The real test – and our practice test – includes questions on how to couple and uncouple trailers as well as how to handle inspections.

Do you know if the converter dolly air tank drain valve should be open or closed when driving double trailers? This is the kind of question you will learn the answer to on our practice test. The test features 20 questions in all and you need to answer at least 80% correctly to pass. That means you need to get at least 16 questions right. All questions are multiple choice just like the real test and they are drawn from the Montana CDL Handbook, which is the same resource that is used for the actual endorsement test. Our practice test also features progress tracking and answer explanations to further aid your learning. So are you ready to assess your double and triple trailer knowledge? Take our practice test now to see how you would do if you took the real exam today. As an added bonus, this practice test is formatted just like the real test to better prepare you for your visit to the DMV. Take the test now.
