About the Texas CDL Hazmat Exam

The Texas CDL Hazardous Materials Endorsement Test is the DPS-administered knowledge exam for drivers who need an H endorsement, or an X endorsement when combined with tank vehicle authority, to transport hazardous materials in amounts requiring placards. Texas DPS says first-time H endorsement applicants must complete ELDT, submit the state HME application materials, take the Hazardous Materials Exam, complete fingerprinting after the DPS office process, and obtain TSA security threat assessment clearance before issuance. The operational content comes from Section 9 of the Texas Commercial Motor Vehicle Drivers Handbook 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.

Exam sponsor: Texas Department of Public Safety under FMCSA, TSA, and DOT hazardous materials rules. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Texas CDL Hazmat: Suggested Study Strategy

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 gas, flammable solid, oxidizer, poison, radioactive, corrosive, and miscellaneous material distinctions.
4Treat shipping papers, markings, labels, and placards as one communication system; resolve mismatches before transport.
5Review segregation concepts for oxidizers, flammables, poisons, foodstuffs, and dangerous-when-wet materials.
6Plan Texas endorsement logistics early: first-time H endorsement ELDT, DPS office application, fingerprinting after DPS processing, and TSA threat assessment clearance.
