Looking for help as you prepare for your double/triple trailers endorsement test? We’ve got just what you need – our Free Ohio CDL Double/Triple Trailers Practice Test. This is the ideal tool to use to get ready to earn your endorsement so that you can start driving doubles, triples and other combination vehicles. The test has 20 questions in all, each question is multiple choice and covers a topic important to driving combination vehicles safely and effectively, such as: coupling, uncoupling, driving, backing, turning, safety and more. The questions are all taken from the Ohio CDL Handbook. You need to get 80% of the questions right to pass. Here are a couple of sample questions that you could see on the test: Why should the driver lock the tractor glad hands (or dummy couplers) to each other when he or she is not towing a trailer? If there is a major leak in the service line and the driver puts on the brakes, service air pressure will escape and cause what?

If you complete the test and do not earn a passing score or you still feel unsure about your mastery of combination vehicle information, you can take the practice test again and the questions will be reordered. We’ve also included answer explanations, a progress tracker and instant results to enhance your study options.
