Free NM CDL Tanker Vehicles Practice Test 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
Based on 2025 NM commercial driver's license manual
Triple-checked for accuracy
Updated for April 2025

New Mexico is a top state for crude oil production, requiring extensive tanker transport. The demand for commercial drivers who hold both the Tank Vehicles (N) and HazMat (H) endorsements (sometimes referred to as the “X” endorsement) is quite high. You can put yourself at a significant advantage in this market by adding both of these endorsements to your Commercial Driver’s License.
After studying the fundamentals of the Tank Vehicles (N) endorsement, test your knowledge with our New Mexico CDL Tanker Vehicles endorsement practice tests. As an aspiring commercial driver, you need to fully master this subject before being entrusted with the transportation of large volumes of liquid or gaseous materials. Probably you’re already familiar with the official 2025 CDL manual (New Mexico CDL Handbook 2025). It is an essential resource that builds the foundation for your career as a commercial driver, but some students find its content too difficult to study. While this manual has a high importance, it is only a piece of the puzzle.
The learning phase cannot be rushed or skipped. There are no shortcuts, but you can make this entire process easier by adopting a smarter approach. Our Tanker Vehicles endorsement practice tests can also be used as an educational tool, allowing you to learn as you train. Immediate feedback is provided after each question, regardless of the answer you select. This feedback comes with a detailed explanation, which you can note and memorize.
In New Mexico, the MVD is responsible for issuing the “N” endorsement, which allows you to operate class A or class B vehicles hauling liquid or gaseous materials in a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more. This lengthy process can be overwhelming for some, but the key is to break it down into small, achievable steps and arm yourself with patience. The Tank Vehicles endorsement can be yours after paying the necessary fees, passing the written Tank Vehicles knowledge test at your local MVD office and providing a valid DOT medical card.
