View All PlansKansas features flat and open roads, which seem to be a favorite of commercial drivers. Because these rural highways can be long and straight, they can contribute to the risk of driver fatigue. It is crucial to stay alert behind the wheel at all times, especially when driving for extended periods. If you want to drive tankers in the Sunflower State, you must obtain a Tank Vehicles (N) endorsement on your Commercial Driver’s License (CDL). It is granted by the Kansas Department of Revenue’s Division of Vehicles (KDOR), which also publishes the official 2025 CDL manual (Kansas CDL Handbook 2025).
Aspiring commercial drivers who want to drive tankers must pass a knowledge test before they can operate vehicles designed to transport liquids and gases. This test covers important topics such as liquid surge, the pre-trip inspection procedure and emergency protocols. While you can find everything you need in the CDL manual, your chances of passing this exam greatly increase once you consider other alternatives. Our Kansas CDL Tanker Endorsement practice tests are designed to help you pass the official written test on your first attempt by creating an environment similar to what you’ll encounter on the exam day.
Most other tests quietly register your progress and reveal the final score at the end, either when the timer runs out or when all questions have been answered. This method often disappoints students who are unaware of their progress, which can demotivate and discourage them. Fortunately, our practice tests feature an overview of your current session, updated in real time. It tells you how many questions you’ve answered correctly and how many more mistakes you can make before you fail.
If you panic under the pressure of a countdown, you will be pleased to learn that we have no timer on our practice tests, allowing you to take as long as you need before completing each session. If you are curious about the performance of other aspiring commercial drivers on these practice tests, you can also activate the answer popularity feature.
