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.

Frequently Asked Questions
What score do I need to pass the Texas CDL Hazmat test?
Federal CDL rules require at least 80% correct on CDL knowledge tests. Texas administers the Hazardous Materials Exam under the CDL endorsement framework.
Do I need ELDT before taking the Texas Hazmat test?
Yes, if you are applying for the hazardous materials endorsement for the first time. Texas DPS and FMCSA require ELDT before the first-time H endorsement knowledge test.
Do I need a TSA background check for a Texas H endorsement?
Yes. Texas DPS says a CDL with hazardous materials endorsement cannot be issued until the individual completes the TSA security threat assessment and obtains clearance.
Can a first-time Texas HME applicant receive a temporary H endorsement while TSA is pending?
No. Texas DPS says existing HME holders may receive a 90-day temporary endorsement during TSA processing, but first-time applicants will not receive the HME until the assessment is completed.
What is the difference between Texas H and X endorsements?
H authorizes transportation of hazardous materials. X combines tank vehicle and hazardous materials authority when the driver needs both endorsements.
