California is a HazMat powerhouse. With major corridors like I-5, I-10, I-15, and US-101 connecting ports, refineries, and distribution centers, HazMat-certified drivers are in constant demand. Without this endorsement, you cannot legally transport explosives, fuels, industrial chemicals, radioactive materials, or infectious substances—locking yourself out of thousands of specialized, higher-paying jobs.

Age exception for California: Drivers 18-20 years old can obtain the HazMat endorsement, but federal law restricts them to intrastate (within California) transport only. Interstate HazMat transport requires age 21+.

Top California employers requiring HazMat drivers:

  • Petroleum & Energy: Chevron (headquartered in San Ramon), Valero, Phillips 66
  • Pharmaceuticals: Amgen Inc. (Thousand Oaks), Gilead Sciences (Foster City)
  • Chemical manufacturing: Air Products, Linde, numerous ag-chem distributors
  • Ports & logistics: LA/Long Beach port carriers, Central Valley ag transport

What to expect on the official California HazMat test:

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