HAZMAT Endorsement for Truck Drivers


A truck driver who has a Commercial Driver’s License but wishes to deliver loads considered to be hazardous materials must obtain a HAZMAT endorsement first.

1. How to Obtain a  DOT HAZMAT Endorsement on CDL

A truck driver with a Class A, B or C CDL can apply for DOT HAZMAT endorsement by completing these five procedures.

1. Fill out HAZMAT endorsement application through the DMV or TSA
2. Complete a medical screening
3. Pass the DMV written exam (varies by state)
4. Pay fees
5. Submit a TSA Background Security Screening either online or in-person

The following states require an in-person DMV application for TSA Security Assessment

  • Florida
  • Kentucky
  • Maryland
  • Mississippi
  • New York
  • Pennsylvania
  • Texas
  • Virginia
  • Wisconsin

2. Carriers HAZMAT Responsibilities

Truck drivers who have a HAZMAT endorsement typically earn a higher salary than standard drivers with a CDL. When hauling hazardous materials truck drivers are subject to specific responsibilities that go beyond standard requirements set by the DOT.

  • Shipping Paper
  • Placard and Mark Vehicle
  • Loading and Unloading
  • Compatibility
  • Blocking and Bracing
  • Incident Report
  • Security Plan
  • Employee Training


3. HAZMAT Classifications

CLASS 1 – Explosives

CLASS 2 – Gases

CLASS 3 – Flammable Liquid

CLASS 4 – Flammable Solids

CLASS 5 – Oxidizing Substances / Organic Peroxides

CLASS 6 – Poisonous (Toxic) and Infectious Substances

CLASS 7 – Radioactive Material

CLASS 8 – Corrosives

CLASS 9 – Miscellaneous Dangerous goods

  • Environmentally hazardous substances
  • Elevated temperature material
  • Hazardous wastes
  • Marine pollutants

4. Always Have a Copy of the DOT HAZMAT Table in Your Truck

The HAZMAT Table displays the classifications of hazardous materials and breaks them down by division, as well as by specific material. Having the HAZMAT Table with you at all times will allow you to correctly fill out any shipping papers or packages and comply with Hazardous Material Requirements (HMR) and avoid a violation. The most common DOT HAZMAT violation is not having a copy of USDOT hazardous materials registration number.
