The Hazardous Materials endorsement (code H on your license) lets you transport materials that the U.S. Department of Transportation classifies as hazardous in quantities that require placarding. Drivers must pass a knowledge exam, undergo a Transportation Security Administration (TSA) background check including fingerprinting, and renew the endorsement on a regular schedule. The exam draws from chapter 9 of the AAMVA CDL Manual and the Federal Motor Carrier Safety Regulations Parts 100–185, covering hazard classes, shipping papers, placarding, loading and unloading, driving and parking rules, emergencies, and security plans.
