What we sell

Illustrated study material for people preparing for the United States commercial driver's licence (CDL), delivered as downloadable PDF files. Nothing is shipped physically.

This is study material, not a course. It does not issue a licence, a permit or a certificate, it is not affiliated with any state agency or the FMCSA, and it does not replace your training provider or your state's examiner. Where the official state handbooks disagree, the book says so. Your examiner's score sheet always wins.

Your purchase

One payment. There is no subscription and no recurring charge.
Payment is processed by Stripe. We never see or store your card number.
The download link is emailed to the address you enter at checkout, normally within a few minutes.
If a title is sold before it is finished, the checkout and the email say so and give you the date it arrives. You pay the pre-sale price once and receive the finished book in the same folder, at no extra cost.

What you may and may not do with the files

You may read the files on your own devices and print them as often as you want for your own use. You may not resell them, share them publicly, upload them to file-sharing sites or distribute them to third parties.

Refunds

See the refund policy.

Liability

We take care that every figure matches the official state handbooks, and we say on the page when a figure varies by state. Even so, the material is educational: driving decisions, vehicle safety and what you say to an examiner remain yours. To the extent allowed by law, our liability is limited to what you paid.

Changes and governing law

We may update these terms; the date at the top shows when. These terms are governed by the laws of the State of Florida, United States.
