- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 NC commercial driver's license manual
- Triple-checked for accuracy
- Updated for August 2025
Since you’re visiting this site, you must be interested in adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL). This endorsement is an amazing way to expand your job opportunities and increase your earning potential! In North Carolina, you’ll experience the steep and winding roads of the Appalachian Mountains in the west, the Piedmont region with its rolling hills, and the coastal plains in the east with its flat but flood-prone areas. Transporting cargo in North Carolina can be challenging, but it’s worth it for the rewards offered by this career and the additional opportunities available with the Hazmat endorsement.
Drivers interested in transporting materials classified hazardous by the U.S. government need the Hazmat endorsement to take on these specialized, and often higher-paying, jobs. In the Tarheel State, hazardous materials transported include Class A and B explosives, compressed gasses, poisons, flammable liquids, radioactive materials, and other hazardous substances. Some prominent organizations in North Carolina, such as Duke Energy in Charlotte, Syngenta in Greensboro (for agricultural chemicals and materials), and Clean Harbors located throughout the state (handling waste management and hazardous materials cleanup) rely on Hazmat drivers. These are just a few of the many companies requiring this endorsement.
That is a lot of opportunities unavailable to those without the endorsement! Let’s dig into the process! It starts with a mandatory fingerprinting and background check conducted by the Transportation Security Administration (TSA). Do this right away as the results can take weeks, and that time can be used to study and practice for the second step: the DMV knowledge test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations for hazardous materials. With a score of 80% on North Carolina’s 30-question knowledge test, you will pass the test (North Carolina CDL Handbook 2025).
What’s great is that we have streamlined this process for you. Our North Carolina DMV Hazmat Endorsement practice tests are designed to avoid unnecessary information and resemble what you will face on the official DMV test. Receiving immediate feedback on each response, you’ll learn as you go instead of at the end of the assessment. Once you receive your TSA results and feel prepared, you’ll visit the DMV with the necessary documents, pay the fees, and pass the test.
