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.

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.

South Carolina CDL Hazmat Study Tips from Top Performers

1Memorize the basic shipping description order: identification number, proper shipping name, hazard class, and packing group when one applies.
2Practice placarding decisions separately for Table 1 any-quantity materials and common Table 2 aggregate-weight situations.
3Learn all hazard classes and the key divisions for gases, flammable solids, oxidizers, organic peroxides, toxic substances, and radioactive materials.
4Treat package labels, markings, placards, and shipping papers as one communication system; mismatches should be resolved before transport.

Frequently Asked Questions

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.
