Free MN CDL Tanker Vehicles Practice Test 2025

Minnesota’s Department of Transportation (MnDOT) regulates tanker truck operations and ensures that all safety standards are met. Drivers must hold a Commercial Driver’s License (CDL) along with a Tank Vehicles (N) endorsement to operate such vehicles, and in some cases, a HazMat (H) endorsement is also required.

Industries relying on tanker trucking services include agriculture, manufacturing, and fuel distribution. Since Minnesota is one of the nation’s top dairy producers, there are a large number of milk tankers. These trucks collect milk from dairy farms and deliver it to processing plants across the state. If you also hold a HazMat (H) endorsement, you can look for jobs in agriculture, where tanker drivers transport fertilizers, chemicals, and pesticides. Because some of these materials are toxic to humans and the environment, it is crucial that they be handled exclusively by professionals.

The first step to becoming a tanker driver in Minnesota should begin weeks before taking the official Tank Vehicles knowledge exam. Before you can get behind the wheel of an actual tanker, you must study the Tank Vehicles section presented in the official 2025 CDL manual (Minnesota CDL Handbook 2025). When you feel ready, we recommend you give our Minnesota CDL Tank Vehicles Endorsement practice tests a try.

These Minnesota CDL Tanker Endorsement practice tests are designed to closely resemble the official written exam, allowing you to evaluate your knowledge in an environment similar to what you’ll encounter at a Driver and Vehicle Services (DVS) exam station. The only notable difference is the lack of a timer, which we have omitted for your convenience.

There is no secret recipe for success. While our practice tests can significantly boost your chances of passing the exam, it’s up to you to become consistent in your training. As you begin, don’t get discouraged by several low scores in a row. It is perfectly normal to fail on your first few attempts, but you can use a special feature to your advantage.

Immediate feedback is provided after every question, regardless of your selected choice. This feedback highlights the correct answer and contains a detailed explanation, allowing you to learn from your mistakes. We recommend noting this explanation in a notebook, which can become an essential reference.
