CDL practice tests
Private practice site. Chapbook is not a government agency and is not affiliated with or endorsed by any department of motor vehicles, U.S. Citizenship and Immigration Services, or any state or county agency. These are practice tests written by us to help you study. They are not the official test, and passing here does not give you a licence, a permit, a card, or a certificate of any kind.

What practice can and cannot do here
These tests prepare you for the written knowledge tests. They are not entry-level driver training, they issue no training certificate, and they do not satisfy any training requirement. The requirements page for your state links to the federal Training Provider Registry for that step.
Where this section stands
No CDL test is live yet. This section arrives in a later wave, after citizenship and the first four car states. The bank is written from the knowledge areas in 49 CFR 383.111, and every question ships only after two independent checks against the regulation it tests, the same gate the live banks passed. We would rather open a section late than open it with questions we have not checked twice.
