With your Virginia Class A CDL in hand, you’re just a few steps away from unlocking even more lucrative job opportunities. Obtaining the T endorsement legally allows you to operate double or triple trailer combinations! To do so, you must pass the Double-Triple Trailer (T) Endorsement Knowledge Test. Our Free Virginia CDL Double-Triple Trailer (T) Endorsement Knowledge Practice Tests are designed to mimic the official test and help ensure first-time success. Our practice tests are packed with instant feedback, hints, and AI tools to speed up the learning process.
Don’t let a failed attempt slow you down! If you fail, the Virginia Department of Motor Vehicles (DMV) requires a minimum one-business-day waiting period before retesting. After three attempts, a retesting fee applies. With our practice tests, you can avoid delays and extra fees by passing the first time!
The official exam in Virginia consists of 20 multiple-choice questions. To pass, you must answer at least 16 questions (80%) correctly. Like the official test, all questions on this knowledge test are based on the latest Virginia CDL Manual. With a focus on safe driving techniques to avoid rollovers, coupling and uncoupling procedures, techniques to prevent jackknifing, braking procedures for long combination vehicles, safe following distances, and trailer inspection procedures, our fully comprehensive practice tests include all the material needed to pass the exam.

With major interstates like I‑64, I‑81, and I‑95 and major hubs through cities like Richmond, Norfolk, and Northern Virginia, the demand for CDL drivers with T Endorsements is strong, as are the additional job prospects! Top employers, including UPS, Old Dominion Freight Line, and XPO Logistics, actively seek these qualified drivers.
Why stop at one endorsement? We recommend you earn additional endorsements like tank vehicles (N), hazardous materials (H), passenger (P), school bus (S), and X Combo (tank + hazmat). Each endorsement adds marketability to your CDL through the additional types of loads you can transport. Our practice tests help you pass these endorsement tests with flying colors.
Most double and triple trailer combinations use air brakes, so you’ll also need to pass the Air Brakes Knowledge Test to remove the “L” or “Z” restriction from your CDL. We have you covered with Virginia Air Brakes practice tests too!
This practice test is the second of two in our Virginia CDL Doubles and Triples Knowledge Practice Test series. Explore our full set of other endorsement and air brake practice tools, tailored to Virginia DMV requirements.
