HazMat Endorsement
A HazMat endorsement (H endorsement) is an additional certification added to a CDL that allows a driver to transport hazardous materials as defined by DOT regulations. It requires a TSA background check and knowledge test, and must be renewed every 5 years.
In Depth
Hazardous materials include flammable liquids, explosives, radioactive materials, corrosives, and other DOT-classified substances. Drivers transporting HazMat must display proper placards, carry shipping papers, and follow strict safety protocols for loading, parking, and emergency response.
The HazMat endorsement process includes passing a written knowledge test and a TSA security threat assessment (background check). The background check costs approximately $86 and takes 1–3 weeks. Disqualifying factors include certain felony convictions and being on the terrorist watch list.
HazMat loads typically pay premiums of $0.10–$0.30/mile over standard freight rates due to the additional training, certification, and liability involved.
Usage Example
Example: 'With my HazMat H endorsement, I can haul fuel tankers and chemical loads that pay $0.20/mile more than dry van.'
