Texas is the heart of America’s energy industry—and HazMat drivers are essential to keeping it running. Major corridors like I-10, I-35, and I-45 connect refineries, chemical plants, and distribution centers across the state. From Houston’s petrochemical hub to the oil fields of West Texas, HazMat-certified drivers are in high demand and command premium pay.
Why get HazMat certified in Texas? Without this endorsement, you cannot legally transport petroleum products, chemicals used in the energy sector (sulfuric acid, ammonia), agricultural chemicals, or medical waste. That means missing out on thousands of specialized, higher-paying jobs in the Lone Star State’s booming logistics sector.
