Eager to receive your combination vehicles endorsement? If so, it’s well worth your time to take our free Pennsylvania CDL Combination Vehicles Practice Test. This multiple choice exam will thoroughly test your understanding of combination vehicles and show how ready you are to begin driving combination vehicles, like doubles and triples and other large commercial trucks, safely. The practice test features 20 questions and you need to get at least 16 right to pass. Here are some sample questions that are like the ones on the test so you know what to expect: what gear should you have the tractor engine in after you uncouple the trailer and are inspecting the trailer supports? The tractor protection valve is meant to close automatically when the air pressure falls into what manufacturer-specified pressure range? Test questions cover such subjects as rollover risk, braking, backing up, driving around corners, combination vehicle care, coupling and uncoupling and more.

All test questions are drawn from the combination vehicles section of the Pennsylvania CDL Handbook, which is also what the actual endorsement test is based on. You can take our practice test multiple times and there is never a charge. We will also reorder the questions each time you take the test. Also, to help you learn more about combination vehicles we have included answer explanations.
