How to Get a CDL in Tennessee: Requirements, Steps, and Cost (2026)

By Drivio

I wouldn't walk into a DSD office without knowing what order all of this goes in, because the state's not going to let you jump ahead. Skip one and you'll start over. Tennessee CDL requirements run through Driver Services (part of the Department of Safety & Homeland Security), and I bring up that long name only because DSD's what you'll be reading on your paperwork and nobody there's going to call it the DMV.

Quick Answer: The Steps to a Tennessee CDL

Tennessee CDL steps start with age and medical rules. Complete ELDT if it is your first commercial license. Pass the written knowledge test for a CLP. Hold that permit for at least 14 days. Then pass the three-part skills test. That is the whole game. I can't give you a fee that'll still be right by the time you read this, so go look at tn.gov/safety when you're ready to budget.

CDL Classes and Endorsements in Tennessee

Class A's what I'd guess you came here for, and it's the license for combination rigs over 26,001 pounds where the trailer's over 10,000 by itself, so picture every tractor-trailer you've ever been stuck behind on I-40 or I-24.

Class B is for heavy single vehicles. Straight trucks, dump trucks, many buses. For a city bus or concrete mixer, that's usually a TN CDL Class B.

Class C covers smaller vehicles. It includes 16 or more passengers, driver included. Smaller trucks hauling placarded hazmat land in this class as well.

Endorsements add written tests. Common ones include:

  • Passenger
  • School bus
  • Tanker
  • Doubles/triples
  • HazMat

HazMat also requires a federal security threat assessment and fingerprinting. Restrictions get printed on your license if you skip endorsements or take your test in a vehicle without certain features.

This one trips people up. You can pass the skills test in an automatic truck and get an automatic-only restriction. Before you book that automatic, I'd call a couple of the outfits you'd want to work for and ask if they run manuals, since plenty of them do.

Eligibility: Age, Medical Card, and Driving Record

The federal age rule is firm. You can get a CDL at 18 to drive intrastate only, meaning within Tennessee borders. You need to be 21 for interstate driving or any HazMat endorsement. If you live in Memphis and want to run loads across the bridge into Arkansas, you wait until 21.

Nobody's getting around the DOT physical, and what you walk out of it with is a Medical Examiner's Certificate signed by a certified examiner. Bring the long form and the card. DSD will scan it into your record. Don't laminate it before DSD sees it. Some offices need to copy it.

You need a valid Tennessee driver license. Your record should be reasonably clean. A DUI or a leaving-the-scene charge on there can knock you out altogether, whereas a few speeding tickets probably won't, though I'd expect a future employer to ask you about them.

Bring these documents:

  • current license
  • Social Security card or acceptable proof
  • birth certificate or passport
  • proof of Tennessee residency
  • DOT medical certificate

I'd pull up tn.gov/safety and go down the list with the actual papers in your hand the night before. Offices in Franklin and Murfreesboro get busy. Losing half a day over a missing utility bill is about the most annoying thing that can happen in this whole process, and I've seen it more than once.

ELDT and the CLP-to-CDL Path

If you're going for your first Class A or B, federal rules have made you take Entry-Level Driver Training since February 2022, so there's no getting out of it. The provider must be registered with FMCSA. This applies before you take the skills test. Some endorsements also require ELDT. You cannot self-study your way around this if you have never held a CDL.

The written test comes first. The CDL test Tennessee requires has 50 questions. Getting to 80 percent means you can only afford to miss 10 of them. Two answers often look right. The test asks what you "must" do versus what you "may" do. Slow down on those.

Pass that test and DSD issues your Commercial Learner's Permit. From there the clock's running, and you can't sit for skills until that CLP's been in your wallet at least 14 days. Use that time to complete ELDT and practice. You cannot take the skills test without proof of ELDT completion in the FMCSA registry.

The skills test has three parts. The pre-trip inspection goes first, and you'll be talking your way around the truck out loud, telling the examiner what you're looking at and what you'd want to see there. Basic control skills include:

  • straight-line backing
  • offset backing
  • parallel parking Then the on-road drive. One bad habit fails you fast: not checking mirrors before every turn.

For the written exams, use Drivio's free Tennessee CDL practice test at /cdl/tennessee. If you've been wondering how to get your CDL in TN without burning a test attempt, I'd run through that thing a bunch of times first, since it's set up like the real one and you'll see pretty quick which sections you're weak on.

Tennessee CDL Cost and Timeline: What to Expect

Tennessee CDL cost varies. Plan for a range. Self-study and borrowing a truck may cost a few hundred dollars. A private CDL school can cost several thousand. Most people land in between.

Cost components include:

  • CLP fee
  • CDL license fee
  • skills test fees
  • ELDT tuition
  • DOT physical Some schools bundle everything. Some charge separately for retests. Ask about separate retest charges before you pay.

Your timeline depends on training. The fastest path is three to five weeks. That includes:

  • studying
  • passing the written test
  • the 14-day CLP hold
  • ELDT
  • scheduling the skills test Got a full-time job on top of all that? Then I'd pencil in more like two or three months and not beat yourself up about it.

Don't trust whatever number you heard from a buddy, because state fees get changed. DSD updates them without warning. I'd take the figures straight off tn.gov/safety before you set a budget, and I'd ignore that old forum thread from 2022 somebody's going to send you.

Tennessee CDL FAQ

How long's the whole Tennessee CDL process going to take me? At minimum about three weeks because of the mandatory 14-day CLP hold. Between a month and three's pretty normal once you've got training in the mix.

What's it going to run me, all in? If you study on your own and just pay testing costs you might be out a few hundred bucks, and a full school's going to be several thousand. Confirm current Tennessee CDL cost on tn.gov/safety.

What is the difference between a CLP and a CDL? A CLP is a learner's permit. It lets you practice in a commercial vehicle with a qualified CDL holder beside you. A CDL is the full license.

Do you need ELDT? Yes, for first-time Class A or B applicants and certain endorsements. It must come from an FMCSA-registered provider.

Can you get a CDL at 18? Yes, for intrastate driving only. Hit 21 before you cross a state line for work or haul hazmat.

How long's the general knowledge test? 50 questions for general knowledge. Miss more than 10 and you'll be coming back for another try.

Common Questions From First-Time CDL Applicants

Do you need experience first? No. Most Tennessee schools train people with zero truck experience. They'll usually start you off creeping around a parking lot and won't put you out on a highway till you've gotten used to where the back of that thing actually is.

As for the skills test being hard, I'd call it fair, and honestly the pre-trip's the part that gets folks because they hurry and don't listen to what they've been asked to do. I'd say every single check out loud, even if you feel dumb doing it.

Failed a section and wondering what now? You can retest. Tennessee allows retakes after a waiting period, usually a day or more. You pay a retest fee. You may not have to redo all three. Confirm with DSD.

Class A gives the most job options. If you know you'll be driving a dump truck or a bus, a B will do fine, and C's for the passenger van and small hazmat crowd.

Read the Tennessee CDL manual once. Then drill practice questions daily. Use Drivio's free Tennessee CDL practice test at /cdl/tennessee. I'd rather see you do ten minutes every morning with your coffee than one miserable all-nighter.

Get your medical card early. Schedule ELDT early. The day your CLP's active is the day I'd go looking for a skills date. Slots in Clarksville and Johnson City fill fast. Then walk in ready.
