What it takes
To haul placarded hazardous materials, you need the hazmat (H) endorsement: a knowledge test, plus a TSA security threat assessment with fingerprinting and a background check. Carriers also require hazmat training, refreshed regularly.
Why get it
Hazmat opens up more loads and often higher pay, and many tanker jobs require it. Even on van or flatbed freight, having the endorsement makes you more useful to a carrier.
What changes on the road
Placards, shipping papers within reach, route and parking restrictions, tunnel rules and extra inspection attention. Carriers expect careful drivers with clean records.
Questions drivers ask
How do I get a hazmat endorsement?
Pass the hazmat knowledge test at your state licensing agency and complete the TSA security threat assessment (fingerprints and background check). Your state's DMV site lists the steps and fees.
Does hazmat pay more?
Often, yes. Hazmat loads and hazmat tanker work usually pay a premium, and the endorsement opens more jobs.
