About the Mississippi CDL HazMat Endorsement Test Exam
The Mississippi CDL Hazardous Materials Endorsement Test is the written knowledge test for drivers seeking H endorsement authority, or X endorsement authority when hazardous materials are combined with tank vehicles. Mississippi DPS lists H as Hazardous Materials knowledge test only and X as Combination Tank Vehicle and Hazardous Materials. Mississippi administrative rules require TSA security threat assessment procedures when adding or renewing the HazMat endorsement, and first-time H endorsement applicants must complete FMCSA ELDT HazMat theory before the knowledge test. The knowledge content comes from Mississippi CDL Manual Section 9 and federal hazardous materials transportation rules covering shipping papers, emergency response information, package markings and labels, placards, hazard classes, loading and unloading, segregation, bulk packaging, security, route and parking rules, and incident response.
