Hazardous materials

Complete federal training and security steps in the correct order.

Prepare hazmat knowledge, ELDT, TSA security threat assessment, shipping papers, placards, segregation, loading, routes, security and incidents.

First H endorsement can trigger ELDT

Complete hazmat theory training through a provider listed in the FMCSA Training Provider Registry before the state knowledge test when the federal rule applies.

TSA security threat assessment

The H endorsement requires a federal background process in addition to the California knowledge test and medical/license requirements.

The X endorsement authorizes the combined tank and hazardous-material operation when all requirements are satisfied.

Shipping papers, loading, segregation, prohibited materials, parking, routes, security, emergency response and incident reporting all matter.
