About the South Carolina CDL Hazmat Exam
The South Carolina CDL Hazardous Materials Endorsement Test is the written knowledge exam for drivers who need an H endorsement, or an X endorsement when combined with tank vehicle authority, to transport hazardous materials or hazardous waste in amounts requiring placards. SCDMV administers CDL knowledge testing at branch offices and lists separate CDL application, knowledge test, and five-year Hazmat license fees. First-time H endorsement applicants must complete FMCSA Entry-Level Driver Training before the H knowledge test, and applicants must complete the TSA hazardous materials endorsement security threat assessment. The operational test content comes from the South Carolina CDL manual and federal hazardous materials rules for shipping papers, emergency response information, placards, package markings and labels, hazard classes, segregation, loading and unloading, routing, parking, and security awareness.

Federal CDL rules require at least 80% correct on CDL knowledge tests. SCDMV administers the hazardous materials endorsement knowledge test under the CDL endorsement framework.
