Tennessee CDL practice test

The CDL general knowledge test follows federal standards, so these questions apply in Tennessee just as they do nationwide — it is the same test that earns your TN commercial learner's permit (CLP). Below the test you'll find the Tennessee-specific steps to actually get licensed.

Tennessee CDL General Knowledge Question 1 of 10

The most effective way to fight driver fatigue is to:

Tennessee endorsement tests

General knowledge is the test above. Each endorsement has its own written test and its own question pool — practise the ones your job needs, with the TN steps on each page.

Getting your CDL in Tennessee

In Tennessee, apply through the state licensing agency (TN DMV / DOT). The core steps are the same across states:

  1. Get a valid TN driver's license and provide required identity documents.
  2. Pass the DOT physical with a certified medical examiner and carry your medical card.
  3. Pass the written knowledge tests (general knowledge plus any endorsements you need).
  4. Hold your commercial learner's permit (CLP) for the required waiting period.
  5. Complete Entry-Level Driver Training (ELDT) with a registered provider, if required.
  6. Pass the skills test — pre-trip inspection, basic controls, and road test.

Exact fees, permit hold times, and document requirements are set by Tennessee. Confirm the current details with the TN licensing agency before you go.

What is different in Tennessee

Licensing in Tennessee runs through the Tennessee Department of Safety and Homeland Security. The part that catches people out is not the test — it is the medical certificate, because the way it reaches the state changed in 2025.

Tennessee implemented the National Registry rule on 15 June 2025, ahead of the federal deadline. Your examiner’s result is transmitted to Tennessee electronically, the examiner is no longer required to issue the paper certificate, and a physical copy of Form MCSA-5876 is no longer accepted as proof of a valid medical examination. What you still file yourself is the Self-Certification Affidavit (form SF1480) — uploaded through the e-Services portal or handed in at a Driver Services Center.

The self-certification has an online path

Tennessee lets you upload the SF1480 Self-Certification Affidavit through its Driver Services e-Services portal instead of visiting a centre — not every state offers that. The affidavit selects which of the four commerce types applies to you, and it is required regardless of how your medical certificate travels.

Tennessee moved to electronic medical certification on 15 June 2025. The Tennessee DOT physical page has the rest — what the exam checks, what happens if your certification lapses, and the Driver Services contacts worth having.
