As a commercial driver, you must be prepared for the unexpected changes that might occur on the road. Unpredictable weather, traffic accidents, or road construction can alter your route. These situations demand quick decision-making from professional drivers who deliver cargo on tight schedules. During winter, New Jersey often experiences a lot of snowfall. When you’re behind the wheel of an 18-wheeler, it is crucial to know how to prevent skids. Any time you brake hard, you should check your side mirrors to make sure the trailer stays where it’s supposed to be.

About the New Jersey CDL

You’ll need a Class A CDL to drive combination vehicles in New Jersey and across its borders. The Motor Vehicle Commission (MVC) handles the licensing process and publishes the official Commercial Driver License Manual (New Jersey CDL Handbook 2025). We recommend reading this manual multiple times during your learning phase, especially Section 6 (Combination Vehicles). You will learn how to handle road emergencies, safe driving practices for combination vehicles, and coupling and uncoupling procedures.

The practice test that you’re about to take is the fourth in our New Jersey CDL Combination Vehicles Practice Tests series. When used regularly, this intuitive tool can be the difference between failing and passing the official combination vehicles knowledge test. Your dream career will not be realized by chance or luck. This path demands thorough preparation, where perseverance and consistent effort over several weeks will lead you to success.

Add flexibility to your learning phase by studying whenever your schedule allows. On average, it takes 10 minutes to answer all questions and finish this practice test. You can run quick practice sessions during a busy day, or strengthen your knowledge with extended study sessions in the evening. Please pay attention to the detailed explanations provided for each question. They explain the reasoning behind the correct answers, helping you understand the material instead of memorizing it. For future reference, you should note this feedback in a notebook or notebook app.

You cannot master general commercial driving theory overnight, but our Free New Jersey CDL Permit Practice Test can significantly boost your learning potential. Ace your theory exams on your first attempt by training with our practice tests throughout your learning journey.
