Do you need ELDT for a hazmat endorsement?
Yes, for first-time applicants. Under 49 CFR Part 380.603, any driver applying for the hazmat (H) endorsement for the first time on or after February 7, 2022 must complete ELDT theory before taking the state CDL knowledge test for hazmat.
Renewal is different. If you already held the H endorsement before February 7, 2022, renewing it does not require ELDT.
Existing CDL does not exempt you. Having a Class A or Class B CDL does not waive the hazmat ELDT requirement.

Hazmat and tanker together (the X endorsement)

Is ELDT.IO legit? Verify us on the FMCSA registry
ELDT providers are registered, not approved, the FMCSA does not approve or endorse specific providers. It maintains a Training Provider Registry (TPR) of registered providers. ELDT.IO is listed on that registry.
