In practice
Since February 7, 2022, you need ELDT from a registered provider if you're getting:
- a Class A or Class B CDL for the first time,
- an upgrade from Class B to Class A, or
- a passenger (P), school bus (S) or hazmat (H) endorsement for the first time.

The training has two parts. Theory covers topics like vehicle systems, hours of service and safe operation, and ends with an assessment. Behind-the-wheel training happens on a range and on public roads. The provider reports your completion to FMCSA's Training Provider Registry, and your state checks the registry before letting you take the skills test or the hazmat knowledge test.

EXAMPLE: a driver who has held a Class B since 2019 and now wants a Class A must complete Class A ELDT before the Class A skills test, because it's an upgrade. The same driver adding hazmat for the first time also needs hazmat theory.

Questions
Is there a minimum number of hours?
No. ELDT sets a curriculum, not hours. Theory ends with an assessment you must pass, and behind-the-wheel training is proficiency-based: the provider signs off when you can perform the skills.
Does ELDT expire?
Your completion record stays on the registry. If you got your CDL or endorsement before February 7, 2022, ELDT doesn't apply to that license or endorsement.
