So you want to become a tanker truck driver in New Jersey. You’re probably aware of what it takes to obtain a Tank Vehicles (N) endorsement on your Commercial Driver’s License (CDL). There’s a 20-question knowledge test you need to pass before the MVC allows you to operate vehicles designed to transport any liquid or gaseous materials within a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more.
You should prepare for this test several weeks in advance, studying liquid cargo handling, liquid surge management, emergency procedures and the pre-trip inspection required before you drive the vehicle. During this time, you’ll explore the fundamentals of commercial driving and its endorsements as explained in the official 2025 CDL manual (New Jersey CDL Handbook 2025).
Since New Jersey offers a wide range of career opportunities for tanker truck drivers, we recommend checking the Hazardous Materials section as well. Refineries in Linden, Perth Amboy, and Bayonne provide plenty of jobs for drivers who hold a CDL with an ”X” endorsement, which consists of the Tank Vehicles (N) and HazMat (H) endorsements pair.
Although the CDL manual provides crucial information for commercial drivers, beginners often find the material too difficult to study. It takes a while to familiarize yourself with this key part of the transportation industry, but studying for your dream career shouldn’t feel like a chore you would prefer to skip. That’s why we provide a series of CDL Tank Vehicles endorsement practice tests specific to the state of New Jersey.
Due to their versatility, you can use them to learn more about this subject. Each practice test comes with a series of features that can significantly enhance your experience and boost your learning journey. After selecting an answer, you will receive immediate feedback consisting of a detailed explanation, so you won’t have to wait until the end of the test to identify and fix your mistakes. And since you get unlimited attempts, don’t be discouraged if you fail. See it as an opportunity to do better and slowly improve your score after each session.
