The ELDT timeline at a glance
Every number in this table comes from a federal rule or agency guidance. The parts with no fixed time depend on you, your school and your state.
| Stage | Federal timing rule | What sets your pace |
|---|---|---|
| ELDT theory (online) | No minimum hours. You must cover every required topic and score at least 80%. | How many hours a week you study, and the course format |
| Completion reporting | Provider submits by midnight of the 2nd business day after you finish | Weekends and holidays don't count as business days |
| Commercial learner's permit | No skills test in the first 14 days after your CLP is first issued. A CLP is valid for no more than one year from first issue. | State knowledge tests, medical certificate, appointment availability |
| Behind-the-wheel (Class A and B) | No minimum hours. Training ends when your instructor certifies proficiency on the range and public road. | Your experience, school schedule and equipment |
| Window between theory and BTW | Finish the second part within one year of finishing the first (not H) | Which part you start with |
| Skills test or H knowledge test | Your state verifies your ELDT in the registry first | State testing appointments |
| TSA threat assessment (H only) | TSA recommends enrolling at least 60 days ahead | Fingerprinting appointment, background check processing |
Theory: the part you control
Federal rules don't set a minimum number of hours for theory. The curriculum just has to be covered completely, and you have to pass the assessment at 80% or higher. In practice, your pace comes down to two things.
- Consistency. Short, regular sessions beat one marathon weekend. Retention matters, because the assessment covers everything.
- Curriculum size. Class A and Class B cover five sections with more than 25 units. Hazmat has 13 units. See the Class A topics or the hazmat units.
Be wary of any course that promises a finish time or "instant certification". Providers can't control how fast you learn, and they can't report a completion that hasn't happened.
The waits you can plan around
Reporting: up to two business days
After you pass, the provider submits your completion through FMCSA's Training Provider Registry by midnight of the second business day. Finish on a Friday afternoon, and the deadline lands on Tuesday night. Plan for that before you book a test date.
The CLP 14-day wait
You can't take the CDL skills test in the first 14 days after your CLP is first issued. Theory doesn't need a CLP, so finishing it before or during that wait saves time. See the best order.
The one-year window
For Class A, Class B, passenger and school bus training, you have one year from finishing the first part of ELDT to finish the second. If you finish theory in January, book your behind-the-wheel training well before the next January. Hazmat has no window, because it's theory only.
Does ELDT expire?
The federal rules we reviewed don't list an expiration date for a completed ELDT record. The time limit that does exist is the one-year window between the two parts of Class A, Class B, P and S training. Separately, a CLP is valid for no more than one year from first issue, and some states have rules of their own. If a long time has passed since you trained, check with your state licensing agency before you schedule a test.
Two common ways to sequence it
Theory first, then school
Finish Class A theory online before CDL school starts, so school days go to driving. Keep behind-the-wheel inside the one-year window. How to get ahead before school.
Hazmat add-on
Start the TSA application and hazmat theory the same week. The TSA step usually takes longer, so by the time it clears, your completion is long since reported.
Company training a group?
Timelines get easier when drivers start theory together. Plan group enrollment and we'll help line up the courses each driver needs.

Timing questions
Does ELDT expire?
Federal rules don't list an expiration date for a completed ELDT record. They do set a one-year window: for Class A, Class B, passenger and school bus training, you must finish the second part within one year of finishing the first. Hazmat has no such window. If a long time passes before you test, ask your state licensing agency whether anything else applies.
Can I finish ELDT theory in one day?
There's no federal minimum time, so some drivers finish quickly. But no honest provider can promise a finish time, because you still have to complete every topic and pass with 80%.
How long does hazmat ELDT take?
Hazmat theory is self-paced, like the others, and has no behind-the-wheel portion. The longer wait is usually the TSA security threat assessment. TSA recommends enrolling at least 60 days before you need a decision. See the hazmat path.
Why isn't my completion showing yet?
Providers have until midnight of the second business day after you finish, so weekends and holidays can stretch it. After that, here's what to check.
