Free New Jersey CDL Permit Practice Test: General Knowledge 2025

Here is a free New Jersey CDL permit practice test! This practice test, one of several we offer, will help you prepare to pass the official CDL General Knowledge test.

We’re sure that you were advised to study the official New Jersey Commercial Driver License Manual (New Jersey CDL Handbook 2025) to get ready for the official knowledge test. This manual contains all the material on which you’ll be tested. Now that you’ve read a lot of it, do you think you can pass the official knowledge test? If so, great! We want to wish you the best of luck. But if you feel you could use a little more help to pass it – well, that’s what we’re here for.

Answering the questions on this practice test will help reinforce what you read in the CDL manual and make the material easier to remember. The practice test is based on the official state CDL manual, just like the official knowledge test. It is up to date as of November, 2025. There are 50 multiple-choice questions, which will assess your understanding of such topics as emergency preparedness, vehicle components, and driving in various situations. However, this practice test differs from the official knowledge test in the extra features it provides to help you learn, including a hint and an explanation of the correct answer for each question, and an automated assistant for even more help.

By passing the official knowledge test, submitting to a medical examination, and meeting a few other requirements, you’ll become eligible for a Commercial Learner’s Permit (CLP). Your CLP will allow you to practice commercial driving under the supervision of a CDL holder. When you’ve sufficiently mastered commercial driving, you can take the official skills test for a Commercial Driver’s License (CDL). The skills test has three parts: basic vehicle maneuvers, a pre-trip inspection of your vehicle, and a road test.

Once you have a CDL in hand, the world of commercial driving will be open to you. There are many economic opportunities to explore in New Jersey. The state’s proximity to New York City and Philadelphia, its warehousing and distribution centers, and its seaports (notably the Port of Newark, one of the busiest in America) create a high demand for truckers.

Driving in New Jersey can be pleasant, but it isn’t always easy or efficient because of heavy traffic congestion. Interstate 95 (known in the state as the New Jersey Turnpike) is the most important north-south superhighway on the Eastern seaboard for both commuter and commercial traffic. But it is routinely plagued by heavy traffic congestion, not only in the New Jersey area but also in Connecticut, the Washington, DC area, and south Florida.
