DE CDL Double/Triple Trailers Practice Test 3 2025

Before you can get a “T” endorsement, you must pass an official knowledge test to demonstrate your understanding of how to competently pull multiple trailers. The practice test can help you improve your chances of passing the official knowledge test on your first try, using 20 questions that mimic the actual testing experience. Based on your answers to those questions, the practice test identifies the information you should further study to correctly answer at least 80% of the 20 questions on the official knowledge test. That’s the score you’ll need to receive your endorsement, and you can depend on the practice test to thoroughly prepare you to achieve it.
