New Jersey CDL General Knowledge Test 9 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Updated for December 2025, this New Jersey General Knowledge practice test contains another 50 questions based on the official CDL (Commercial Driver’s License) manual. You can use this test to prepare for the General Knowledge portion of the NJ CDL exam. These questions are multiple-choice, with three possible answers for each question. Only one of those answers is correct. If you’re not sure about the correct answer, you can use the hint provided for each question. Each hint points you to the correct answer without giving away the correct answer itself. This should allow you to make an informed decision about the correct answer, even if you don’t actually know it. There is no time limit for completing this practice test. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers.

Passed my CDL Knowledge test in Under 10 Minutes – This Course Really Works.
I'm a 59-year-old male and recently took the CDL course to help me pass the CDL knowledge test and the passenger endorsement test in New Jersey. Thanks to the well-constructed and easy-to-follow modules, I passed the test in under 10 minutes! One of the most helpful features was the Question Marathon. It allowed me to zero in on the questions I struggled with the most, helping me focus my study time where it really mattered. Repeating those key areas made all the difference when test day came. The test simulation was also incredibly useful. It gave me a real feel for what the actual exam would be like, reducing my anxiety and boosting my confidence. By the time I sat for the real test, I felt fully prepared. I highly recommend this course to anyone looking for an effective, no-nonsense way to study and earn their commercial license.
