Prepanchor Air Brakes Cheat Sheet + General Knowledge Diagnostic for the CDL Knowledge Tests

Every Prepanchor CDL pack is knowledge-test practice, not Entry-Level Driver Training (ELDT). It doesn't replace the training some drivers must complete.

For anyone starting on the CDL knowledge tests who wants the air brakes numbers on one page and to see which general knowledge topics need the most work.

We'll send what you asked for, then study emails for this exam. First, one email to confirm your address. Unsubscribe in one click.

Questions

Is it really free?

Yes. You give an email address, confirm it, and we send a link to the cheat sheet and the diagnostic. Unsubscribe in one click.

Is this CDL training?

No. It is knowledge-test practice, not Entry-Level Driver Training (ELDT). FMCSA's ELDT rules apply to anyone getting a Class A or Class B CDL for the first time, upgrading from Class B to Class A, or getting a school bus, passenger or hazmat endorsement for the first time. That training comes from a registered training provider. Who needs ELDT, on fmcsa.dot.gov.

Is this official?

No. Prepanchor is a private company, not affiliated with FMCSA, any state DMV or any other licensing agency. We write our own questions. Explanations are based on state CDL manuals, in our own words.

Free from licensing agencies

Your state's commercial driver manual is free, and the knowledge tests come from it. Washington's is linked here as an example: get the one from your own state. FMCSA explains who needs ELDT.
