Tennessee's documentation requirements include a distinctive rule worth knowing well before your appointment: the state does not accept I-94 work authorizations for CDL purposes.
Tennessee requires full citizenship or lawful permanent resident status and does not accept I-94 work authorizations from non-citizens for CDL purposes. This is a genuinely distinctive rule compared to many other states, and worth confirming applies to your situation well before your test appointment.
Your Own Vehicle
Tennessee does not maintain a testing fleet. You must bring your own registered, insured vehicle appropriate for the CDL class you're testing for, whether Class A, B, or C.
Medical Certificate Status
Your Medical Examiner's Certificate can be scanned and emailed to DI.CDL.Medcert@tn.gov ahead of time. Confirming it's properly on file before your appointment, rather than assuming it arrived correctly, is a reasonable precaution.
Out-of-State Transfers
If you're transferring a CDL from another state, you'll need proof of Tennessee residency (30 days). Knowledge and skills tests may be waived for valid CDL holders transferring in, simplifying the process for drivers already licensed elsewhere.
