The Tank Vehicles (N) endorsement, once obtained on your Commercial Driver’s License (CDL), allows you to operate vehicles transporting liquids or gases in tanks whose individual capacity is larger than 119 gallons and whose aggregate capacity is at least 1,000 gallons. This endorsement opens up many doors in your commercial driving career, especially in Indiana, where the agricultural industry has a high demand for drivers qualified to transport liquid fertilizers, pesticides and herbicides to farms. However, you’ll also need a HazMat (H) endorsement to transport toxic materials.

Before starting each trip, you must perform a pre-trip inspection of your tanker truck. This inspection consists of several steps, and it ensures that everything is in order and that your vehicle does not pose a risk to other traffic participants. The pre-trip inspection, along with various aspects of the Tank Vehicles endorsement, is discussed in the official 2025 CDL manual (Indiana CDL Handbook 2025). Beginners are initially introduced to this valuable resource since the questions on the official knowledge test are based on this manual. While you take notes and tackle each topic one by one, we offer you an effective solution to test your knowledge.
Consisting of 20 questions, our Indiana CDL Tank Vehicles Endorsement practice tests closely reflect the official written exam, allowing you to familiarize yourself with its content and format. With unlimited attempts, you can train as often as you want, being limited only by your own schedule. To maximize your potential, we recommend training on these practice tests for several weeks. During this time, you’ll notice how your score gradually increases as you develop a better understanding of this subject.
The answer popularity feature allows you to gain insight into other students’ sessions. A statistic is displayed as a percentage near each answer choice, indicating the overall sentiment. If you wish to take these practice tests entirely with your keyboard, you can press the “Shift + ?” key combination to display a list of commands. Additionally, you can activate the voiceover feature by pressing the “V” key, which reads the text on your screen aloud using an artificial voice.
