The U.S. government has deemed certain materials hazardous and developed an endorsement process that is quite a bit more involved than other endorsements. This is due to the safety precautions that are necessary to protect drivers, the public, and the environment. The good news is that these added layers, once met, set you apart from other CDL drivers and provide additional opportunities and often higher pay. In fact, adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is one of the best ways to get ahead, as employers will often pay more for the added certification.
Driving in the Lone Star State means facing steep grades in Hill Country, arid deserts in the west, flooding or hurricane conditions on the coastal plains, and urban congestion in Houston, Dallas, and Austin. Compound those challenges with hazardous materials, and you can see why more preparation is necessary (and more reward and opportunity afforded!).
Hazardous materials commonly transported in Texas include petroleum products, energy-sector chemicals (sulfuric acid, ammonia), agricultural chemicals, and medical waste. Major companies such as ExxonMobil (Houston), Dow Chemical (Freeport), Valero Energy (San Antonio), and Sysco (Houston) rely on endorsed drivers.

The first major step in the endorsement process is to ensure you have all Entry-Level Driver Training (ELDT) requirements met. Then, you’ll need to undergo a fingerprinting and background check by the Transportation Security Administration (TSA). Because results can take weeks, start this step immediately and use the wait time to prepare for the final hurdle: the DMV HazMat Knowledge Test. This test covers federal regulations, safe handling, packaging, limits, and transport configurations. That’s quite a range of material! To pass, you’ll need to score at least 80% on the 30-question exam in Texas (Texas CDL Handbook 2025).
Our online practice tests are designed to closely match the format of the official DMV exam. Each question includes instant feedback to improve retention and speed learning. Further, we have not one but several HazMat Practice Tests in our Texas series. Check out another one here: https://driving-tests.org/texas/tx-cdl-hazmat-practice-test/. Additionally, check out our Air Brakes Practice Tests (https://driving-tests.org/texas/tx-cdl-air-brake-practice-test/) and our Combination Vehicles Practice Tests.
Once you’ve confirmed ELDT requirements are complete, your TSA clearance arrives, and you’ve mastered the practice materials, you’ll visit the DMV, present the required documents, pay the fees, and pass your test!
