About the TN CDL Hazmat Exam

The Tennessee CDL Hazardous Materials Endorsement Test is the written H endorsement knowledge test for CDL drivers who transport materials requiring placards under DOT hazardous materials regulations. Tennessee requires the TSA HAZPRINT security threat assessment before HME issuance, then administers the vision and knowledge tests at a Driver Services Center after TSA clearance. The tested knowledge tracks Tennessee CDL Manual hazmat content and federal requirements for shipping papers, emergency response information, package markings and labels, placards, hazard classes, loading and unloading, cargo segregation, route and parking rules, security awareness, and emergency procedures. First-time H endorsement applicants must complete FMCSA ELDT theory training when ELDT applies.

Exam sponsor: Tennessee Department of Safety and Homeland Security Driver Services, with TSA security threat assessment and FMCSA federal CDL standards. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

TN CDL Hazmat: Suggested Study Strategy

1Memorize the basic shipping description order: identification number, proper shipping name, hazard class or division, and packing group when required.
2Separate Tennessee licensing logistics from operating rules: TSA HAZPRINT, ELDT, fees, and required documents are prerequisites, while placards, shipping papers, loading, and emergency response are daily operating knowledge.
3Learn which placarding rules are quantity based and which materials require placards in any amount.
4Practice scenarios where shipping papers, labels, markings, and placards conflict; the safe answer is to stop and resolve the discrepancy before transport.
5Study route, parking, railroad crossing, tunnel, safe-haven, and security questions as real operating-practice questions, not just definitions.
