View All PlansAs you explore new career opportunities, you’ll notice a high demand for tanker drivers in the chemical manufacturing sector. In South Carolina, this industry relies heavily on tanker trucks to transport sulfuric acid, caustic soda, and other chemicals. Due to their hazardous nature, these substances should be handled exclusively by professionals who have an “X” endorsement on their Commercial Driver’s License, which represents the combination of the Tank Vehicles (N) and HazMat (H) endorsements.
Driving is a skill you learn with practice. Nobody is born a talented commercial driver, and the most successful ones don’t have a secret for their expertise. As you begin the process of becoming a tanker driver in South Carolina, you’re probably looking for materials to study. Issued by the South Carolina Department of Motor Vehicles (DMV), the official 2025 CDL manual (South Carolina CDL Handbook 2025) contains essential information on this subject, which every aspiring commercial driver should know.
To assist you in your learning journey, we offer a series of CDL Tanker Vehicles Endorsement practice tests specific to the state of South Carolina. Test your knowledge with this tool before showing up at the DMV location for the real test. If you fail any of our practice tests, you can learn from your mistakes, thanks to the immediate feedback feature, which provides a detailed explanation of the correct answer after you select a choice. This way, you won’t have to wait until the end of the test to know where you need to improve.
Each practice test has been updated for October 2025. All 20 questions are based on the latest version of the CDL manual, which you can keep open while you actively train on our practice tests. Getting several wrong answers in a row can be frustrating, especially if you’re trying to simulate the official written exam. If you are not satisfied with your current progress, simply press the designated restart button to start from the beginning. However, you should know that the order of the questions will be randomized.
