There are plenty of opportunities for commercial drivers in Louisiana, where the demand for tanker drivers is quite high. Those who have a Tank Vehicles (N) endorsement on their Commercial Driver’s License (CDL) are at an advantage in this market, where such skills are highly valued. If you also want to drive tankers, you must pass a written knowledge test on tank vehicles and a skills test in a vehicle of the license class you are applying for if you haven’t yet done so for your CDL.
Tankers often have a higher center of gravity than standard trucks. The liquid inside can shift when braking and turning, significantly affecting balance and handling. Drivers must be cautious about this dynamic movement, which also increases the stopping distance. There’s a lot to learn before you get behind the wheel of an actual tanker, but all this effort will pay off in the long run.
As you start your learning journey, take a look at the official 2025 CDL manual (Louisiana CDL Handbook 2025). It contains essential information about commercial driving, but most students find the material too difficult to study. Those who want to master this subject will change their perspective and adopt a smarter approach. Fortunately, there is an effective alternative that has helped many students pass the official knowledge exam on their first attempt.
Our Louisiana CDL Tanker Endorsement practice tests can be used as an educational tool by those who are still in the learning phase. Once you select an answer, immediate feedback is provided along with a detailed explanation of the correct answer. Aspiring commercial drivers can use this feature to learn more about tankers while familiarizing themselves with the content and format of the official written exam.
There’s no timer, so you can take as long as you need to complete each session. We recommend looking through the CDL manual for the correct answers while you are training on these practice tests. Although you won’t be able to do it during the official exam, it gives you an opportunity to understand the reasoning behind each correct answer.
