Free NJ CDL Double/Triple Trailers Practice Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 NJ commercial driver's license manual
- Triple-checked for accuracy
- Updated for March 2025
New Jersey has its own amazing attributes. And when combined with its proximity to major cities like New York and Philadelphia, you better believe adding a Double/Triple Trailers endorsement to your Commercial Driver’s License (CDL) will add an enormous amount of variety and income-producing marketability to your credentials. The main requirement is passing a 20-question multiple-choice knowledge test with a score of 80% (16 correct answers). That’s it! After passing, you’ll receive the “T” endorsement on your CDL, authorizing you to pull two or three trailers (where laws allow) (New Jersey CDL Handbook 2025).
In the Garden State, you only need to be 18 to add this certification to your CDL; however, you must be at least 21 to drive across state lines. Even with a Doubles/Triples Trailers endorsement, you’re only allowed to pull double trailers in New Jersey. However, double trailers are often used throughout New Jersey for the transport of pharmaceutical supplies (New Jersey is a major hub for medical supplies), food and beverages (New Jersey has more people per square mile than any other state!), consumer goods, electronics, and fruits and vegetables. Have I caught your attention? You may be saying to yourself, “Yes! How can I best prepare for the test?”
To put it mildly, the information available online is in no short supply. As such, studying for this endorsement can quickly become overwhelming. That’s why we’ve created a systematic, focused approach with our online New Jersey CDL Double/Triple Trailers practice test. Up to date as of March 2025, it includes 20 multiple-choice questions that resemble what you will face at the MVC on your test day!
Have you ever taken a practice test and received all the feedback at once at the end of the assessment? That’s information overload! With our practice test, you’ll receive immediate, thorough feedback on each answer. This real-time approach helps you solidify the content as you go. So, what are you waiting for? Once you’ve prepared, practiced with our free tests, and feel ready, simply apply at the MVC, bring your documents, pay the required fee, pass the official test, and watch as options (and profitability) open at your feet.
