If you want to drive a semi-truck, bus, or other commercial vehicle, you'll first have to get your commercial driver's license (CDL). The process is more involved than applying for a regular license, since the vehicles it allows you to drive are much bigger and more difficult to drive than typical cars and trucks.
Nationally, the CDL process is regulated by the Federal Motor Carrier Safety Administration (FMCSA), and in Tennessee, it's overseen by the Department of Safety (DOS)—specifically, through the Driver Services Division.
Who Can Get a TN CDL?
To be eligible for a Tennessee commercial driver's license, you will need:
- A valid, non-CDL license.
- Proof that you are a U.S. citizen or a legal permanent resident (see below).
Drivers under 21 years old will be restricted to driving within TN, per FMCSA regulations. You must be at least 25 years old to earn a school bus endorsement.
Tennessee Commercial Learner's Permits
In order to get your TN commercial driver license, you must first get a commercial learner's permit (CLP).
Before applying, you might want to look into a CDL training course. It's not required by either the DOS or the FMCSA, but it is recommended to help you prepare for all exams involved in the process.
When you're ready, schedule an appointment with your local Driver Services Division office. You will need:
- The proper medical paperwork—see below.
- The appropriate fee for the type of permit you're getting (see below for details).
- Your valid driver's license or a Tennessee state ID.
- 2 proofs of TN residency.* Documents must not be photocopies. Examples include:
- Current utility bills.
- Current vehicle registration or car titles.
- Lease agreement/mortgage papers.
- For more examples, see the full list compiled by the DOS.
- Proof of U.S. citizenship/lawful permanent resident status. You may bring:
- A valid, non-expired U.S. passport.
- A certified birth certificate.
- A certificate of naturalization.
- See the full list of examples provided by the DOS.
You may have to submit to a driving record check, where your record in all 50 states and Washington, D.C. over the past 10 years.
Finally, you'll have to take the proper written exams for the type of CDL you want. Once you pass, you will be issued your Tennessee commercial learner's permit.
*NOTE: The TN Department of Safety will also accept proof of a relationship with a Tennessee resident as proof of TN residency. Acceptable relationships include your:

CLP Restrictions in TN
You will be required to hold your CLP for a specific period of time before you're able to take your road test for your full Tennessee commercial driver's license. While federal laws mandate a holding period of at least 14 days, this could be different for your state. Check with your local Driver Services Division office to confirm what the holding period is in your state.
The Federal Motor Carrier Safety Administration also requires you to drive on public roads only while you have your commercial learner's permit, and only while accompanied by a full CDL holder.
TN Commercial Driver's Licenses
To turn your CLP into a CDL, you'll have to wait for the appropriate amount of time and then take your skills tests. In Tennessee, the DOS requires the skills testing to include:
- Pre-trip vehicle inspection.
- Basic vehicle control.
- On-road driving test.
Arrange to take your skills tests with the same type of vehicle you intend on driving with your commercial driver license. If you can not, you may have a restriction placed on your CDL.
Schedule your test by calling the Department of Safety at (615) 502-4179 any time between 8 a.m. and 4:30 p.m., Monday through Friday.
After passing your skills tests and paying the appropriate fee, you will be issued your full TN commercial driver's license.

Classes of TN Commercial Driver Licenses
The Federal Motor Carrier Safety Administration has established several different types of CDL, which allow you to drive different types of vehicles. The classifications include:
- Class A CDL—Allows you to drive a combination of vehicles over a certain weight, such as a tractor-trailer.
- Class B CDL—Permits you to drive a single vehicle over a certain weight, like a box truck.
- Class C CDL—Applies to all other types of vehicles over a certain weight not covered by Class A or Class B CDLs.
The written and skills tests you're asked to complete may vary, depending on the class of CDL you're applying for. Different types of commercial driver's license may also require different fees.
For more information, see our guide to CDL classifications.
Tennessee CDL Endorsements & Restrictions
You can add endorsements to your CDL to make you eligible to drive a greater number of commercial motor vehicles. Obtaining an endorsement requires you to take additional written and/or skills tests and pay an extra fee from the DOS.
You can receive endorsements to drive:
- HAZMAT vehicles.
- Tank vehicles.
- Double or triple trailers.
- School buses or other passenger vehicles.
- To drive a TN school bus, you must be at least 25 years old.
A restriction is the opposite of an endorsement, and is placed on your commercial driver's license to limit the number of vehicles you will be permitted to operate. You may receive a restriction if:
- You take your skills test in the wrong type of vehicle.
- You can not operate an air brake system.
- You can not operate a manual transmission.
Restrictions can typically be taken off your CDL with additional testing, paperwork, or fees.
