View All PlansThe Tank Vehicles (N) endorsement, once added to your Class A or Class B Commercial Driver’s License (CDL), allows you to drive vehicles designed to transport liquids or gases in a tank or tanks with an individual rated capacity of more than 119 gallons and a combined total capacity of 1,000 gallons or more. This qualification is highly valued in New Hampshire, where the fuel and petroleum distribution industry has a high demand for tanker drivers. However, you will also need a HazMat (H) endorsement to transport hazardous materials that are toxic to humans or the environment.
Weather can be quite challenging in the Granite State, especially during the winter months, when snow and ice test the skills of even the most experienced commercial drivers. When you haul 8,000 gallons of fuel from Manchester to Conway, there’s no room for error. You must fully master the controls of your tanker truck, and that includes the management of liquid surge.
Whether you are just getting started as a beginner or you’re an experienced driver who wants to obtain the “N” endorsement, the official 2025 CDL manual (New Hampshire CDL Handbook 2025) is your main point of reference. This manual explains various aspects of commercial driving, including the safe operation of tanker trucks, the pre-trip inspection, loading and unloading procedures, and handling emergency situations.
On its own, this resource might not be enough to help you pass the Tank Vehicles knowledge exam on your first try. To maximize results in your learning phase, we recommend adopting a smarter approach and taking advantage of our complete series of New Hampshire CDL Tanker Vehicles Endorsement practice tests. Each practice test has been updated for November 2025 and has 20 questions based on the CDL manual.
Your training sessions are not timed, and with unlimited attempts, you can practice as often as you want. Each question has multiple answer choices, but only one is correct. If you make a mistake, we provide immediate feedback, which you can use to deepen your understanding of this subject. And if you ever feel like starting a session from scratch, simply use the designated restart button to wipe your current progress and start all over again.
