Does ELDT Expire? How Long Is It Valid?
ELDT itself: permanent. Hazmat endorsement: 5-year TSA renewal, no ELDT retake.
ELDT is a permanent record
When you complete an FMCSA-approved ELDT course with a TPR-registered provider, the completion is recorded on your driver record at the FMCSA Training Provider Registry. That record is permanent. The federal ELDT requirement, once satisfied for a given license class or endorsement, stays satisfied. For the full federal-rule context, see the main-domain ELDT training requirements page and our What Is ELDT? guide.
There is no federal ELDT expiration date, no refresher requirement, and no scheduled retake. If you do nothing else, your ELDT compliance remains valid indefinitely for that license or endorsement.
Endorsements have their own renewal cycles
What CAN expire are the underlying licenses and endorsements. CDLs themselves are state-issued and have state-defined renewal cycles (commonly 4–8 years depending on the state — check your state's specific ELDT requirements page for the exact cycle). Renewing a CDL does not require retaking ELDT.
Hazmat endorsements are the special case: every 5 years; new TSA background check required, ELDT NOT repeated. The TSA fingerprint check is the renewal trigger, not the training. You do not retake Hazmat ELDT to renew your H endorsement. The main-domain How to Get a Hazmat Endorsement guide covers the renewal process end-to-end.
Common edge cases
CLP lapse: a Commercial Learner's Permit is a state-level instrument with its own validity (often 180 days, varies by state). If your CLP expires before you complete the CDL skills test, you may have to reapply for a new CLP — but the federal ELDT record on the FMCSA TPR is not affected. You don't retake ELDT.
Switching states: if you move and transfer your CDL to a new state, the new state queries the FMCSA TPR for your ELDT record. The training travels with you across states; you don't retake ELDT to transfer your CDL. State-by-state hubs are at https://states.academyofdla.com/.
Adding a new endorsement after holding an old one: each NEW endorsement (post-February 7, 2022) requires its own ELDT course. Old endorsements are not affected — you only do ELDT for the new add. Our Which CDL Endorsement Should I Get? guide helps you choose between H, P, and S and explains which endorsements require ELDT (vs Tanker N and Doubles/Triples T, which don't).
