About the NC CDL HazMat Exam
The North Carolina CDL Hazardous Materials Endorsement Test is the written knowledge test for commercial drivers who need the H endorsement to transport hazardous materials requiring placards or covered select agents and toxins. The test is based on N.C. Commercial Driver License Manual Section 9 and federal hazardous-materials rules, with emphasis on shipping papers, emergency response information, placards, labels, markings, loading, unloading, segregation, bulk packaging, driving and parking rules, route restrictions, security awareness, and emergency response. Applicants also need the TSA HME Security Threat Assessment, and first-time H endorsement applicants generally must complete FMCSA-approved ELDT HazMat theory before taking the knowledge test.
Assessment
Written CDL endorsement knowledge test covering hazardous-materials recognition, shipping papers, placards, labels, markings, loading and segregation, emergency response, route and parking rules, driver responsibilities, security awareness, and North Carolina/Federal endorsement requirements. NCDMV does not publish a separate HazMat item count in the reviewed public sources, so 30 reflects common CDL endorsement practice rather than a published NC-specific count.
Time Limit
No separate official North Carolina HazMat endorsement knowledge-test time limit was found in the reviewed NCDMV or FMCSA sources.
Passing Score
80% minimum on CDL knowledge tests
Exam Fee
Varies by North Carolina commercial license, permit, endorsement, and transaction; TSA HME threat assessment fee is $85.25 for new or renewing applicants effective January 1, 2025, with a possible $41.00 reduced TWIC rate for eligible North Carolina applicants.
