Whether driving through the steep grades and winding roads of the Appalachian Mountains in eastern Tennessee, the rugged terrain of the Cumberland Plateau, or the rolling hills and plains in the central part of the state, Tennessee is a gorgeous state with much to offer. If adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is your objective, you’ve come to the right place. Let’s dive into how the Hazmat endorsement increases your marketability and recruitment potential and can result in higher pay!
The Hazmat endorsement permits drivers to transport materials that the U.S. government has judged hazardous. This responsibility is taken very seriously, and many additional requirements come into play. The endorsement process alone includes several hurdles to ensure your safety and protect the people and environment. Hazardous materials often transported in the Volunteer State include petroleum products, agricultural chemicals, industrial chemicals, explosives, and construction-related chemicals. There are many high-level organizations in Tennessee that require the endorsement for cargo transport. FedEx (Memphis headquarters), Eastman Chemical Company (Kingsport), Nissan North America (Smyrna), and Pilot Flying J (Knoxville) are a few examples.
First, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check. Results from TSA can take weeks to arrive. You’ll want to use that time to study and practice for the second hurdle: the DMV knowledge test. The knowledge test addresses federal regulations, substance handling, material packaging, quantity limits, and transport configurations for hazardous materials. You’ll need a score of 80% on Tennessee’s knowledge test, which is made up of 30 questions (Tennessee CDL Handbook 2025).
If all this sounds a little overwhelming, it doesn’t have to be. Keep your eye on the prize of more opportunities and potentially higher income. Our online Tennessee DMV Hazmat Endorsement practice tests are strategically designed to avoid any extraneous information you’d find by online search. We get straight to the point and have designed our practice tests to mimic what you will face on the official DMV test. We also provide immediate feedback on each response instead of waiting until the end of the assessment and bombarding you with corrections. Once you receive your TSA results and feel ready, you’ll visit the DMV with the necessary documents, pay the fees, and pass the test with flying colors.
