Texas is known for scorching hot weather, which often causes droughts and water shortages. During this time, tankers transport potable water for municipal use and agricultural irrigation across the Lone Star State. Because these vehicles have a higher center of gravity, they are often more difficult to control when compared to standard trucks. Liquid surge doesn’t make the drive easier, either. This phenomenon can occur during acceleration, leading to changes in the liquid’s momentum and creating strong forces that affect the stability of a tanker. An experienced tanker driver will know how to slightly mitigate this effect, but this skill can only be developed with hands-on practice.
Before you can get behind the wheel of an actual tanker, you must obtain a Tank Vehicles (N) endorsement on your Commercial Driver’s License (CDL). The Department of Motor Vehicles (DMV) requires all Texas residents to pass a written Tank Vehicles knowledge test before they are trusted with driving vehicles designed to transport liquids or gases in individual tanks of more than 119 gallons and a combined capacity of 1,000 gallons or more.
We’ll help you pass this exam and fulfill your dream of becoming a tanker driver, but you must know that there are no shortcuts you can take. The learning phase marks the beginning of a difficult but rewarding career, so it is crucial to pay attention to the concepts explained in the official 2025 CDL manual (Texas CDL Handbook 2025). After you’ve read the CDL manual’s discussion of tankers a few times, give our intuitive tool a try. It’s always better to be safe than sorry, so we created an environment closely reflecting the one you’ll encounter at the DMV location.
As you train with our Texas CDL Tanker Vehicles Endorsement practice tests, you’ll notice how your score naturally improves with time. It is perfectly normal to fail on your first few attempts, so we recommend disregarding your score while you are still studying for this endorsement. All 20 questions have multiple answer options, but only one is correct. Because your choice gets registered as soon as you click on it, avoid making unfortunate mistakes and only select an answer when you’re confident in your choice.

- First-time TX CDL and CLP applicants
- CDL holders adding endorsements
- TX CDL renewal applicants
