HazMat (Hazardous Materials) are products that pose a risk to health, safety, or property during transportation. Examples include explosives, flammable liquids, gases, radioactive materials, and corrosives. Federal and state regulations strictly control how these materials can be transported by road.
A HazMat endorsement is an additional qualification added to your CDL that authorizes you to transport hazardous materials in a placarded vehicle. It's represented by the letter "H" on your license (or "X" if combined with Tanker).
Higher pay: HazMat drivers earn nearly $11,000 more per year compared to non-HazMat drivers. Job security: Demand for HazMat drivers is growing faster than average. More opportunities: Many trucking companies specifically seek drivers with HazMat certification.
