TN CDL Practice Test 2026: Tennessee DOS Fees & Guide

Tennessee is arguably the logistics capital of the South. With FedEx’s World Hub in Memphis and major interstates (I-40, I-65, I-24) crisscrossing the state, a CDL is a golden ticket to a stable career here.

The Tennessee Department of Safety and Homeland Security (DOS) manages the licensing. This 2026 guide covers the fees, rules, and practice questions you need.

1. Tennessee CDL Fees (2026)

Tennessee offers one of the most affordable 8-year licenses in the country.

ItemCostValidity
Learner's Permit (CLP)$14.001 Year
Class A / B License$70.008 Years
Endorsements (Each)$2.50With license
Duplicate License$12.00If lost/stolen

2. The “Hardship” License Rule

Unique to Tennessee, if you have a suspended driver’s license for certain non-safety reasons (like unpaid child support), you might still be eligible for a restricted license, BUT this rarely applies to CDLs.

  • Warning: You cannot hold a CDL with a suspended base license. Tennessee is part of the Driver License Compact, so tickets in other states will haunt you here.

3. Medical Certification

You must submit your DOT Medical Card to the DOS.

  • Submission: You can upload your medical card online via the TN Dept of Safety e-Services portal.
  • Self-Certification: Most drivers for FedEx, UPS, or OTR carriers will select “Non-Excepted Interstate” (NI).

4. Tennessee Practice Questions

1. You are driving on I-40 through the mountains near Knoxville. You see a sign for a "Runaway Truck Ramp." These ramps are designed to:
A. Allow you to rest.
B. Stop a vehicle with failed brakes safely.
C. Let faster traffic pass.
Correct Answer: B.
Tennessee has steep grades in the east. Escape ramps use gravel or uphill grades to stop a truck that has lost its brakes. Never block these ramps.
2. In Tennessee, if your blood alcohol concentration (BAC) is found to be ____ or higher while driving a commercial vehicle, you will be placed out-of-service for 24 hours.
A. 0.04%
B. 0.08%
C. Any detectable amount.
Correct Answer: C.
While 0.04% is the DUI limit, any detectable amount of alcohol allows an officer to place you out-of-service for 24 hours.

Conclusion

Getting your CDL in Tennessee opens doors to some of the biggest carriers in the world. Don’t let the written test stand in your way.
