Did 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 2026 CDL manual (Wisconsin CDL Handbook 2026), which is what the 20 questions on the Tank Vehicles knowledge test are based on.
