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.

Top Texas employers requiring HazMat drivers:

  • ExxonMobil (Houston)
  • Dow Chemical Company (Freeport)
  • Valero Energy (San Antonio)
  • Sysco (Houston)
  • Numerous oilfield services and chemical transport companies

What to expect on the official Texas HazMat test:

  • Questions: 30 multiple-choice
  • Passing score: 80% (24 correct)
  • TSA background check: Required—start immediately (takes 2-4 weeks)
  • Topics covered: Federal regulations, substance handling, packaging, quantity limits, transport configurations

How to get your HazMat endorsement:

  1. Apply for TSA fingerprinting now—don’t wait, results take weeks
  2. Study while waiting using our practice tests and the official CDL manual (Texas CDL Handbook 2026)
  3. Pass the DMV knowledge test (80% required)
  4. Visit DMV with documents and fees to receive your endorsement

Our Texas HazMat practice tests mirror the official exam and provide immediate feedback on every question. Learn efficiently—no fluff, just what you need to pass on your first try.
