Learn What It Takes To Get A CDL HAZMAT Endorsement Now 2026 September

CDL Hazmat

After earning a Class A, B, or C commercial driver’s license (CDL), drivers may also need to pass further written and road driving tests to operate special types of commercial motor vehicles. One of the several endorsements that a driver should pass is HAZMAT endorsement to be able to drive vehicles containing hazardous materials. The CDL HAZMAT endorsement consists of two separate endorsements:

1. Class H (Hazardous Materials) - Required for transporting hazardous materials, such as flammable and combustible liquids, gases, or other explosives.
2. Class X (Combination of Tank Vehicles and Hazardous Materials) - Allows a driver to transport hazardous materials in a tank vehicle.

Earning the hazardous materials endorsement (HAZMAT) can be an excellent opportunity for commercial drivers as a lot of companies rely on the transportation of hazardous materials. However, finding drivers with HAZMAT certification can be difficult.

Obtaining a HAZMAT certification is a bit more complicated than the others, as it needs fingerprints, a background check, and written tests to be completed and passed before it can be granted.

CDL HAZMAT Requirements

To qualify as a CDL driver transporting hazardous materials, you must meet both state and federal government criteria. Federal law sets some minimum requirements for getting a CDL and transporting hazardous materials that your state must test for. Federal law also dictates that you undergo a security threat assessment mandated by the Patriot Act and conducted by the Transportation Security Administration.

Materials such as explosives, gases, some solids, flammable and combustible liquids, and other materials that may cause harm are classified as hazardous materials. Without a HAZMAT endorsement, a truck driver will be restricted from transporting materials classified as hazardous.
