The Tennessee skills test
Components: Pre-trip vehicle inspection, Basic vehicle control, On-road driving test.
Test vehicle: You must supply a vehicle representative of the class of CDL you are seeking; the state does not provide a test vehicle.
Where and how to book: Tennessee certifies CDL Third Party Testing Organizations, which you can search by county, city, or ZIP and which charge their own fees. You can also schedule the state road skills test by calling the CDL testing line (615-502-4179) or emailing [email protected]; skills testing is done at designated Driver Services Centers.
Waits and retests: Tennessee does not publish official wait times. Many applicants use certified third-party testers (estimated at roughly $150–$250) to get faster scheduling.
Practice the inspection part with our pre-trip inspection guide. Research dated 2026-07-20; confirm testing details with Tennessee.
