Contact

The fastest way to reach the CDL Prep Hub editorial team is by email. We respond to every message that mentions a specific question, page, or rule on the site, usually within one to two business days.

Editorial corrections

If you spot a mistake in a practice question, an outdated rule, or a broken link, please email editor@cdl-prep-hub.example with the URL of the page and a short description of what should change. We re-review the cited sources (AAMVA CDL Manual, the relevant CFR section, the state handbook, etc.) before making any change, and we credit the reporter in our changelog if they request.

Driving schools and trainers

Schools that would like to use CDL Prep Hub as a homework supplement are welcome to do so without prior arrangement. The site is free, ad-supported, and never paywalled. If you would like a printable PDF of the question bank for classroom use, please reach out and we'll see what we can do.

Press & partnerships

For press inquiries or partnership proposals, please email the same address with "Press" in the subject line. We typically reply within five business days.

Mailing address

CDL Prep Hub is an online-only resource and does not maintain a public mailing address. If you require physical correspondence, contact us by email first and we will arrange the appropriate channel.
