View All PlansDid you know that Wisconsin is one of the leading producers of cheese and milk in the United States? Producing about 25% of the nation’s cheese, the Badger State hosts an annual cheese festival to celebrate its rich dairy heritage. This industry creates plenty of opportunities for those seeking employment in Wisconsin. Commercial drivers with a Tank Vehicles (N) endorsement on their Commercial Driver’s License (CDL) can transport thousands of gallons of milk from dairy farms to distribution centers in major cities like Milwaukee, Madison, and Green Bay.
Driving a tanker vehicle is quite different from driving a standard truck. Liquid surge greatly affects the stability of a tanker and increases the stopping distance. During winter months, stopping at a red light could be a challenge you wouldn’t expect in a sedan, SUV or box truck. As an experienced tanker driver, you’ll know how to manage this phenomenon and how to safely control your tanker, even on black ice. You will begin by studying the official 2025 CDL manual (Wisconsin CDL Handbook 2025), which is what the 20 questions on the Tank Vehicles knowledge test are based on.
We live in a digital age where extensive knowledge of any known subject is available on demand. However, an abundance of information can be overwhelming. What you need in your learning journey is a systematic approach paired with consistency and perseverance. As you study the various aspects of tankers in detail, use our Wisconsin CDL Tanker Vehicles practice tests to evaluate your knowledge. Each Wisconsin CDL Tanker Vehicles Endorsement practice test has been designed to closely resemble the official knowledge exam, with 20 questions based on the CDL manual.
To pass, you’ll need to score at least 80%. There are multiple answer choices for each question, but only one is correct. With unlimited attempts and direct access on any device supporting internet browsers, there’s no limit to how much you can train with this intuitive tool. By pressing the “Shift + ?” combination on your keyboard, you can display a list of keyboard shortcuts. With this feature, you can go through each question even if your wireless mouse’s battery charge runs out. If you wish to start from the beginning, you can always use the restart button to begin a new session.
