The CDL permit (CLP)
The commercial learner’s permit comes before the skills test and the licence. It lets you practise while you train.
The commercial learner’s permit — the CLP — is the document that lets a candidate practise driving a commercial vehicle while they train for the skills test. It is the first step in the sequence, and it is where most people start: you pass the written knowledge tests, get the permit, practise under the permit’s conditions, and then take the skills test for the full licence.
Which knowledge tests the permit requires is the same computation as the licence: General Knowledge at minimum, plus any test that applies to the vehicle you will drive. The requirement matrix on the home page computes the exact list for your class and cargo.
The CLP has a holding period before a skills test, and it stays valid for a limited time. Those are federal rules that change, and this site states them only once verified — it does not guess a number from memory (figures under review). The how-to-get-a-CDL guide walks through the sequence in outline.
The permit carries its own conditions about who must be with you while you drive and what you may haul. Those, too, are rules your state sets from the federal standard, and your state’s agency is the source to rely on.
Book it in the right order — so nothing lapses and nothing gets redone
Every question, every explanation and every state’s requirements on this site are free. The Route is the order: what to book before what, the three clocks that run at the same time — your permit, your medical certificate and, if you need hazmat, your security check — and what has to be redone rather than resumed if one of them runs out. Plus what the skills test day actually contains, and which endorsements are worth the money for the work you want.
What the Route holds
Opens a short sponsor step, then brings you straight back to this page with the Route open. Your answers stay in this tab — they are not sent with you.
This site prepares for a written knowledge test. It is not driver training, it is not ELDT, and nothing on it substitutes for your state's CDL manual or a registered training provider. Air brake procedure, coupling, load securement and hazardous-materials handling are safety-critical, and this site never teaches them as something to do.
Common questions
- What is the CDL permit (CLP)?
- The commercial learner's permit is the document that lets you practise driving a commercial vehicle while you train. It comes before the skills test and the full licence, and it is where most people start. Its exact requirements, holding period and validity are federal and state rules this site states only once verified.
- Which tests does the permit require?
- The written knowledge tests — at minimum General Knowledge, and any other knowledge tests that apply to the vehicle you will drive. The requirement matrix on the home page computes the exact list for your class and cargo. The permit is about the knowledge half; the skills test comes later.
- Do I need a permit before the skills test?
- Yes, a commercial learner's permit comes before a first skills test, and there is a holding period between them. The exact period is a federal rule this site states only once verified. The how-to-get-a-CDL guide walks through the sequence in outline.
