- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 NC commercial driver's license manual
- Triple-checked for accuracy
- Updated for September 2025
Whether you’re looking for the distinct smell of the mountains or the sea salt scent of the coastline, you’ll find it in the terrain of North Carolina. Adding the Doubles and Triples Trailers endorsement to your North Carolina Commercial Driver’s License (CDL) is a must for adding credibility and an assortment of new options and income-producing marketability. The main requirement is passing a 20-question multiple-choice knowledge test. To pass, you’ll need a score of 80%, which means getting 16 correct answers. After you pass, you’ll receive the “T” endorsement on your CDL, authorizing you to pull two or three trailers (where allowed) (North Carolina CDL Handbook 2025).
In the Tar Heel State, you need only be 18 years old to add this certification to your CDL (but you won’t be allowed to haul cargo across state lines until you turn 21). With a Doubles and Triples Trailers endorsement, though, you’re only allowed to pull double trailers in North Carolina. That said, double trailers are used throughout North Carolina for the transport of tobacco products, textiles and apparel, furniture and wood products, and agricultural products like sweet potatoes, corn, poultry, and hogs. Additionally, North Carolina has a growing sector of tech and biotech from the research triangle in Raleigh/Durham/Chapel Hill! This endorsement is the doorway to new opportunities. You may be asking yourself, “How can I best prepare for the test?”
Looking online will quickly become dizzying due to all the information available. What you need is a systematic, focused approach —and that’s precisely what our online North Carolina CDL Double/Triple Trailers practice test offers. Up to date as of September 2025, there are 20 multiple-choice questions that resemble what you will face at the DMV on test day!
If a Tar Heel misses a free throw, they know immediately what went wrong. They don’t have to wait until the review at the end of the game to learn. Our practice test works the same way, providing immediate feedback on each answer in real time. If you miss your shot, you’ll see right away why a different response is correct. Once you’ve studied, practiced with our free tests, and feel ready to roll (pun intended!), simply apply at the DMV, bring your documents, pay the fee, pass the test, and jumpstart your transport career.
