View All PlansWhy should you get the Doubles/Triples ("T") endorsement? Longer Combination Vehicle (LCV) drivers often earn higher pay because the work requires precision and carries great responsibility. Once added to your CDL, this endorsement stays on your license permanently. Only a limited number of Delaware drivers have this qualification. Companies like Estes Express Lines and HMD Trucking are actively looking for skilled commercial drivers qualified to operate LCVs.
Now’s the best time to add the "T" endorsement to your CDL. The DMV requires all applicants to pass a -question knowledge test and pay the endorsement fees. You must provide correct answers for at least 16 (80%) questions to pass.
The Commercial Driver License Manual (Delaware CDL Handbook 2026) is an official resource published by the DMV. Section 7 (Doubles and Triples) discusses topics such as parking techniques, preventing rollovers, coupling and uncoupling twin and triple trailers, and pre-trip inspections specific to LCVs. This section is what our Delaware CDL Double/Triple Trailers Practice Tests are based on. You can use both resources to boost your learning potential and increase your chances of passing the official written test on your first attempt.
You’re about to take the fourth practice test in this series. It is an efficient tool that enables active learning, which many students consider more effective than traditional study methods. Each question has multiple answer choices with only one correct answer. If you are unfamiliar with double and triple configurations, we recommend ignoring your score during your first few attempts. With unlimited attempts and nonstop access, you can retake this practice test as often as you wish.
14 practice sessions were completed in Delaware today. Students like you are using the most efficient tools available to build a clear path to their dream career. You can adopt a similar approach by developing a study routine you can follow consistently. If you haven’t obtained a Class A CDL yet, we recommend training with our Free Delaware CDL Permit Practice Test. Within a few weeks, you’ll be ready to go to the DMV office and ace your theory exams on your first attempt.
