About the Louisiana CDL Hazmat Exam
The Louisiana CDL Hazardous Materials Endorsement Test is the written 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. Louisiana OMV requires every hazmat endorsement applicant, including new, renewal, and change-state-of-record applicants, to have a TSA security threat assessment before issuance and to take and pass the hazmat knowledge test. First-time H endorsement applicants who have never had a verifiable hazardous materials endorsement must complete FMCSA Entry-Level Driver Training before the written test. The operational content comes from the Louisiana CDL Manual 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.

Frequently Asked Questions
What score do I need to pass the Louisiana CDL Hazmat test?
Federal CDL rules require at least 80% correct on each CDL knowledge test. Louisiana administers the HazMat knowledge test under the CDL endorsement framework.
Do I need ELDT before taking the Louisiana HazMat written test?
Yes, if you are applying for the hazardous materials endorsement for the first time and have never had a verifiable hazardous materials endorsement. Louisiana OMV says ELDT is required before the written test in that situation.
Do I need a TSA background check for a Louisiana H endorsement?
Yes. Louisiana OMV says every hazmat endorsement applicant, including new, renewal, and change-state-of-record applicants, must have a security threat assessment before issuance.
How much is the Louisiana hazmat fingerprinting fee?
Louisiana OMV and TSA list the HME fingerprinting/security threat assessment fee as $85.25 for new and renewing applicants.
What is the difference between H and X endorsements?
H covers hazardous materials. X combines tank vehicle and hazardous materials authority, so it is used when a driver needs both tank and hazmat endorsements.
Do Louisiana hazmat transfer applicants need to test?
Louisiana OMV transfer guidance says applicants who have and wish to retain a Hazardous Materials endorsement must successfully complete the written hazmat test and meet the hazmat security requirements.
