CDL Requirements in Kentucky (2026): Steps, Cost & Testing

Requirements verified July 20, 2026 against Kentucky Transportation Cabinet (KYTC), Division of Driver Licensing

Kentucky issues CDLs through the Kentucky Transportation Cabinet (KYTC), Division of Driver Licensing, at its Driver Licensing Regional Offices (licensing moved off the Circuit Court Clerks). You hold a regular license, pay $11 for a Commercial Learner's Permit, hold it 14 days while completing ELDT, then take a three-part skills test given exclusively by the Kentucky State Police in a truck you supply. There are no third-party CDL testers in Kentucky, and — because Kentucky is a TSA self-managed hazmat state — hazmat fingerprinting runs through the Kentucky State Police, not a generic TSA center.

Kentucky runs its CDL program through the Kentucky Transportation Cabinet (KYTC), Division of Driver Licensing. Licensing has moved off the Circuit Court Clerks to state-run Driver Licensing Regional Offices, and the actual road skills test is handled by a separate agency — the Kentucky State Police, which is the only entity that tests CDL applicants in Kentucky. The core process is standard: a regular license first, an $11 Commercial Learner's Permit, a 14-day hold, ELDT through the federal registry, then a three-part skills test in a truck you supply.

Two features stand out. First, there are no third-party CDL testers here — everyone books through the Kentucky State Police, so scheduling early matters. Second, Kentucky is one of just eight TSA 'self-managed' hazmat states: instead of visiting a generic TSA/IdentoGO center, your hazmat fingerprinting and Security Threat Assessment are processed through the Kentucky State Police, with a $138.25 fee and a 5-year renewal cycle.

State fees are modest because the CDL is issued as a prorated add-on to your operator license — figure roughly $57–$83 in state fees for a non-hazmat Class A. The bigger line items are ELDT tuition and a DOT physical, plus the hazmat background check if you need the H or X endorsement.

Eligibility and documents in Kentucky

• Age: at least 18 for intrastate driving; 21 to drive interstate or haul hazmat.
• Proof of identity and lawful presence (REAL ID standard for a REAL ID credential): U.S. birth certificate or valid U.S. passport; immigration documents for non-citizens
• Proof of Social Security number
• Proof of Kentucky residency
• A valid Kentucky driver license
• A Medical Examiner's Certificate uploaded to the FMCSA National Registry, plus a completed CDL medical Self-Certification form
• A list of every state where you have held a driver license in the past 10 years

How to get your CDL: step by step

1. Get your Commercial Learner's Permit (CLP). Pass the required knowledge tests: General Knowledge (all applicants); Combination Vehicles (Class A); Air Brakes (if your vehicle has them); Any endorsement tests you need (P, S, H, N, T).
2. Complete ELDT training. For a first Class A/B CDL or a first hazmat, passenger, or school-bus endorsement, you must train with a provider on the FMCSA Training Provider Registry. Your training provider reports completion to the federal FMCSA Training Provider Registry. KYTC and the Kentucky State Police check that federal record before you can take the CDL skills test, and before the hazmat knowledge test. Kentucky uses no separate state ELDT portal — you find providers on the federal registry. ELDT is not required just to get a CLP. Drivers who held a valid CDL or the relevant H/P/S endorsement before February 7, 2022 are grandfathered.
3. Hold your permit 14 days. Federal rules require at least 14 days before the skills test.
4. Pass the skills test. It has 3 parts: Pre-trip vehicle inspection, Basic vehicle control skills, On-road driving test. The Kentucky State Police (KSP) is exclusively responsible for testing all CDL permit and license applicants — Kentucky does not use third-party skills testers. Schedule the road skills test by calling (800) 542-5990 and pressing 1. Training schools can prepare you and often supply a vehicle, but they do not administer the state skills test.
5. Get your CDL issued. Pay the license fee, submit your medical self-certification, and receive your license (valid 8 years). A REAL ID Kentucky CDL credential has an 8-year lifespan. Kentucky offers standard operator licenses in both 4-year and 8-year terms, and because the CDL is issued as an add-on prorated to your underlying operator license, the original CDL fee is prorated to the time remaining on that license — the full 8-year renewal is $88 (Standard) / $93 (REAL ID). Upgrading class or adding a passenger or school-bus endorsement requires the applicable ELDT plus a new CLP held 14 days before the skills test. A hazmat (H/X) endorsement is tied to the 5-year TSA security-threat-assessment cycle regardless of the CDL term.

Medical certification in Kentucky

Self-certify your category on the CDL Self-Certification form at a Driver Licensing Regional Office or through Kentucky's online myDRIVE/KINDL portal. Since the June 23, 2025 federal National Registry II rule, your certified medical examiner transmits your exam results to the state electronically — non-excepted drivers no longer hand in the paper card.

If your card lapses: If your medical certificate lapses and you are not in an excepted category, your CDL is downgraded to a non-commercial license. Keep your self-certification current and renew your DOT physical on time.

Every CDL holder must self-certify one operating category. The categories offered here:

• NI — Non-excepted Interstate (medical card required)
• EI — Excepted Interstate
• NA — Non-excepted Intrastate (medical card required)
• EA — Excepted Intrastate

What a CDL costs in Kentucky

Kentucky's state fees are low because the CDL is a prorated add-on to your operator license. The bigger costs are ELDT tuition and a DOT physical (~$79–$150). Hazmat adds a $5 knowledge test plus the $138.25 fingerprint/STA fee. The KSP skills retest is $50 (+$2.50 portal fee); the initial road-test fee is not clearly published — confirm with the Kentucky State Police.

See the full national breakdown on our CDL cost guide.

Skills testing in Kentucky State-administered testing

Kentucky administers CDL skills tests through the state; approved public third-party testing is limited or unavailable. Because KSP is the sole tester statewide, availability depends on trooper testing schedules in your region; there is no official published wait time. Book early. The written knowledge test can be retaken as many times as needed (once per day; 24-hour wait after a failure).

Your test vehicle: You must supply your own commercial vehicle representative of the class you're testing for — KSP does not provide a test vehicle. The skills test must be taken in the same class of vehicle you intend to operate.

Endorsements available in Kentucky

Kentucky offers the standard federal endorsements. Adding one usually means an extra knowledge test (and a skills test for passenger and school bus). Tap an endorsement for the full federal process and cost:

• HHazmat — Kentucky is one of the 8 TSA self-managed hazmat states, so the fingerprinting and TSA Security Threat Assessment run through the state rather than a generic TSA/IdentoGO center. You pass the hazmat knowledge test ($5, written only — no oral option) at a Regional Office and complete ELDT if first-time, then a fingerprint-based background check is processed through the Kentucky State Police (KSP) to the FBI and TSA. Fingerprinting is scheduled through the state's vendor (IDEMIA/Universal Enroll); results typically take 30–45 days. The background-check fee is $138.25. A valid TWIC card can substitute — email a copy of the front and back to kytc.twic@ky.gov. The STA (and the H endorsement) must be renewed every 5 years based on your threat-assessment expiration. Schedule or check status with KSP at 1 (888) 655-9655.
• NTanker — Tank vehicles.
• XHazmat + Tank — Combined hazmat + tank; the 5-year hazmat/STA renewal cycle applies.
• PPassenger — Passenger; ELDT required for first-timers.
• SSchool Bus — School bus; requires ELDT and the passenger path, plus S knowledge and skills tests. Adding it carries an extra $9 application fee.
• TDoubles/Triples — Double/triple trailers (knowledge test only, CDL required).

CDL disqualifications

Disqualifying offenses are set by federal law (49 CFR 383.51) and apply in every state — including offenses in your personal vehicle. Kentucky applies the federal 49 CFR 383.51 disqualification framework (mirrored in KRS Chapter 281A and 601 KAR). Sample periods per the state CDL manual: 24 hours out-of-service for any measurable alcohol/controlled substance while operating; 60 days for two serious traffic violations in 3 years and 120 days for three; a 1-year disqualification for a first major offense (e.g., DUI at .04+ BAC or leaving the scene); and a lifetime disqualification for using a commercial vehicle in a felony involving controlled-substance manufacture/distribution. No material Kentucky-only additions beyond the federal baseline were found.

Military skills-test waiver

Active-duty service members, or those discharged within the past 12 months, may qualify to waive the CDL skills test if they have recent experience operating a qualifying military vehicle. The knowledge test is not waived. Apply through KYTC/Division of Driver Licensing.
