Have you ever wanted to know the answers to a test before you take it? While this is not entirely possible, we offer a helpful tool that can help you familiarize yourself with the content and format of the Tank Vehicles knowledge test. In North Carolina, you must pass this test to obtain a Tank Vehicles (N) endorsement on your Commercial Driver’s License (CDL). We’ll help you with this goal by providing a series of CDL Tanker Vehicles endorsement practice tests specific to the state of North Carolina.
All 20 practice questions are based on the official 2025 CDL manual (North Carolina CDL Handbook 2025). This document is an essential resource for every aspiring commercial driver, but some students find its content too difficult to study. We know how tiring studying can be, especially when it is about a complex subject. While driving a tanker is not exactly rocket science, you might actually transport rocket fuel with such a vehicle one day.
In the North Old State, you’re more likely to transport liquid fertilizer. This type of cargo is crucial for agricultural operations, especially during planting seasons. However, hauling 5,000 gallons of liquid ammonium nitrate fertilizer is not an easy task. Such toxic materials should be hauled exclusively by commercial drivers who also possess the HazMat (H) endorsement on their CDL.

Dream big but start small. There are plenty of opportunities for tanker drivers in North Carolina, where your driving skills and knowledge of tank vehicles will be highly valued. Consistency is always preferred over intensity, so we recommend you take small steps toward achieving your career goals. Create a daily routine consisting of multiple training sessions. Since you have unlimited attempts, you can use our practice tests as often as you desire. It is perfectly normal to fail several times in a row during your first practice runs, so you should disregard your score for a while. Instead, focus on identifying and learning from your mistakes.
