Free NY CDL Double/Triple Trailers Practice Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 NY commercial driver's license manual
- Triple-checked for accuracy
- Updated for March 2025
Whether you are interested in driving in the urban areas of New York or the open expanse of its rural landscapes, you’re certain to appreciate the variety of scenery and terrain in the state. Enhancing your New York Commercial Driver’s License (CDL) with a Doubles/Triples Trailers (T) endorsement is an incredible way to increase your marketability and earning potential in the transport industry! The main requirement is passing a 20-question multiple-choice knowledge test with a score of 80% (16 correct answers). That’s really all there is to it. Since this is an addition to your CDL, you’ve already done the heavy lifting of the skills test. Once you pass this knowledge test, you’ll receive the “T” endorsement on your CDL, authorizing you to pull two or three trailers (where allowed) (New York CDL Handbook 2025).
In the Empire State, you must be at least 21 years of age to add this certification to your CDL. This age requirement is federally mandated for interstate transport, so you’ve likely seen this hurdle before. It’s important to note that, even with a Doubles/Triples Trailers (T) endorsement, you’re only allowed to pull double trailers in New York. That having been said, double trailers are often used throughout New York for the transport of consumer goods, agricultural products (upstate New York is well known for its dairy and apple farms), construction materials, manufactured goods, and recyclables and waste. By this point, you’re probably saying, “Great! But how can I best prepare for the test?”
Face it! It’s exhausting looking at all the information online. What you need is a systematic, focused approach —and that’s exactly what we offer. Up to date as of March 2025, it includes 20 multiple-choice questions that resemble what you will face at the DMV on your test day!
As a bonus, while you work through our online New York CDL Double/Triple Trailers practice test, you’ll receive immediate feedback on each answer as you go. Remember: You only need to pass the official knowledge test. Once you’ve prepared, practiced with our free tests, and feel ready, simply apply at the DMV. Then, bring your documents, pay the fee, and pass with flying colors.
