You’re planning to get your Commercial Driver’s License in Tennessee — and you picked a great state to do it. Tennessee sits at the crossroads of America’s freight network, with Memphis serving as one of the world’s busiest logistics hubs and Nashville anchoring a thriving transportation corridor that connects the Southeast to the Midwest. The Volunteer State’s strategic location, combined with its growing trucking industry, creates steady demand for qualified CDL drivers.
But before you can join the workforce driving an 80,000-pound combination vehicle through Nashville, Memphis, or the mountain passes of the Great Smokies, you need to pass the Tennessee CDL exam. The Tennessee Department of Revenue Vehicle Services administers the CDL program under federal FMCSA guidelines, and the process is rigorous by design — because the stakes on the road are real.
This guide gives you everything you need to prepare for the Tennessee CDL test: exact test format, Tennessee-specific requirements, what’s different from other states, and free practice tests covering every knowledge exam you’ll face.

Tennessee CDL Requirements: What You Need to Know
Tennessee follows the federal CDL standards established by the FMCSA under 49 CFR Part 383, with some state-specific requirements administered by the Tennessee Department of Revenue Vehicle Services. Here’s exactly what Tennessee requires:
Age Requirements in Tennessee
| License Type | Minimum Age | Restrictions |
|---|---|---|
| Intrastate (Tennessee only) | 18 years | Cannot drive across state lines |
| Interstate (all states) | 21 years | No state-line restrictions |
| HazMat Endorsement | 21 years | Federal requirement — no exceptions |
Tennessee CDL Fees

| Endorsement Fees | $5 each | Per endorsement added |

Tennessee ELDT Requirements
Since February 7, 2022, all new CDL applicants in Tennessee must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. Tennessee verifies ELDT completion electronically through the FMCSA Training Provider Registry (TPR).
ELDT is required for:
- Original Class A or Class B CDL
- Upgrading from Class B to Class A
- First-time School Bus (S), Passenger (P), or HazMat (H) endorsements
You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before taking the skills test. Your CLP is valid for 180 days in Tennessee.
Tennessee CDL Test Format: What to Expect
The Tennessee CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at Tennessee Department of Revenue driver services locations or approved third-party testing facilities.
Knowledge Tests Overview
| Test | Questions | Pass Score | Required For |
|---|---|---|---|
| General Knowledge | 50 | 80% (40 correct) | All CDL classes |
| Air Brakes | 25 | 80% (20 correct) | Class A & B (if vehicle has air brakes) |
| Combination Vehicles | 20 | 80% (16 correct) | Class A |
| HazMat (H) | 30 | 80% (24 correct) | HazMat endorsement |
| Tanker (N) | 20 | 80% (16 correct) | Tanker endorsement |
| Passenger (P) | 20 | 80% (16 correct) | Passenger endorsement |
| School Bus (S) | 20 | 80% (16 correct) | School bus endorsement |
| Doubles/Triples (T) | 20 | 80% (16 correct) | Double/triple trailers |
All Tennessee CDL knowledge tests follow FMCSA content standards. The passing score is 80% on every test — no exceptions.
Tennessee Skills Test: Three Parts
The Tennessee CDL skills test is administered by approved third-party testers. You must provide your own vehicle for the test, and it must be the same class of vehicle you’re applying for.
| Section | What It Tests | Details |
|---|---|---|
| 1. Pre-Trip Inspection | Vehicle safety knowledge | Verbally identify and explain critical components: engine, brakes, tires, lights, coupling systems |
| 2. Basic Vehicle Control | Backing and maneuvering | Straight-line backing, offset backing, parallel parking, alley dock |
| 3. On-Road Driving | Real-world driving | Lane changes, turns, braking, gear usage, speed management, traffic law compliance |
Tennessee skills test retake policy: If you fail any section, you only retake the failed section. If you fail a knowledge test, you must wait 1 day before retaking. If you fail the skills test, you must wait 14 days before retaking. Additional fees apply for each retake.
What Makes Tennessee CDL Different from Other States?
The core CDL exam is federally standardized — the General Knowledge, Air Brakes, and endorsement tests cover the same material in every state. But Tennessee has specific characteristics that make driving here unique:
Tennessee-Specific Driving Conditions
- Memphis logistics hub: Memphis is home to the FedEx World Hub, making it one of the busiest freight centers in the world. Intermodal operations at the airport and major rail yards create complex drayage patterns and heavy local truck traffic
- Mountain terrain: The Great Smoky Mountains in eastern Tennessee feature steep grades on I-40 and US-441, requiring advanced brake knowledge and gear selection for safe descents
- Cumberland Plateau: Middle and eastern Tennessee’s plateau presents winding descents and elevation changes, particularly on I-40 eastbound, where steep grades demand precise speed management
- Severe thunderstorms: Spring and summer bring frequent severe storms with flash flooding, especially in mountain hollows and river valleys. Sudden visibility reduction and water-covered roads are common hazards
- Winter ice and snow: Eastern Tennessee mountains experience significant winter weather. I-40 frequently closes due to snow and black ice, while the rest of the state deals with occasional ice storms
- Dense fog: The Smoky Mountains are famous for morning fog that can severely reduce visibility, particularly along mountain passes and river valleys
- Tornado alley (Dixie Alley): West and Middle Tennessee experience significant tornado risk, especially March through May. Emergency response and evacuation route knowledge is critical
- Hot, humid summers: July and August bring high humidity statewide, affecting tire pressure, engine cooling, and driver fatigue management
- Nashville basin traffic: Central Tennessee’s urban corridor includes Nashville, with increasing congestion on I-40, I-65, and I-24. Multiple interstates converge here, creating complex interchange navigation
- Automotive industry routes: Tennessee hosts major manufacturing plants including Nissan (Smyrna), Volkswagen (Chattanooga), and GM (Spring Hill). Automotive parts transport creates specialized freight patterns along I-65, I-75, and I-40
- Mississippi River crossings: West Tennessee features major river crossings at Memphis (I-40, I-55) and I-155 near Dyersburg, requiring awareness of bridge conditions, crosswinds, and potential flooding
While the CDL knowledge test itself won’t ask you Tennessee-specific questions beyond what’s in the standard handbook, understanding these conditions will make you a safer driver and help you contextualize the safety rules you’re learning.
