All CDL holders/applicants will receive written notification when the information has posted to their CDLIS record. Once the driver/applicant has received written notification of their approval they can proceed to the circuit court clerk’s office to begin/complete the issuance process. A supply of the CDL applications and Self Certification forms may be obtained from the Administrative Support Section at 502-564-1257. All applicants will be required to successfully pass a knowledge test either in written or oral form, and a vision test. A CDL instruction permit will then be issued that is valid for six (6) months. After the CDL permit is issued, applicants must wait 14 days before the skill test is administered. Applicants must call Kentucky State Police for a skill test appointment.

A permit may only be renewed once in the two (2) year period. If you do not successfully pass the road skills test by the expiration of your CDL instruction permit renewal, you will need to reapply. All fees and written/vision tests will be required prior to a new permit being issued.

Written / Skill Test Fees for CDL Permits

If applying for a Class B or C with P & S endorsements only, the application fee will be $9.00 and there will be no skill test fee required. For all others, the application fee will be $24.00 paid at the respective Circuit Court Clerk's office in their county of residence. Effective September 5, 2006 the new skill test fees for CDL permits, as mandated by House Bill 707, was implemented. HB 707 directs that the skill test fees collected will be placed in the Kentucky State Police CDL skill testing trust fund, and will be used by the State Police to contract with and train civilian CDL skills examiners and to improve the logistics of the CDL skills testing process. It applies only to original CDL permits and will not be levied against duplicate or renewal permits.

  • At the time of issuance of a CDL  permit requiring a skills test, a driver who has held a Kentucky operator license for 30 days or longer will pay a skills testing fee of fifty dollars ( $50.00 ) in addition to the eleven dollar ( $11.00 ) CDL permit fee.
  • At the time of issuance of a CDL permit requiring a skill test to a driver who has held a Kentucky operator license for less than 30 days, a skill testing fee of one hundred fifty dollars ( $150.00 ) in addition to the $11.00  CDL will be collected.

What's on the Knowledge Test?

The Kentucky State Police will give the knowledge test at the local exam stations. Please check with your local Circuit Court Clerk regarding the days and times the examiner will be available.

The knowledge test consists of 50 questions covering a broad range of subjects, including vehicle operations under all kinds of conditions, cargo handling, and vehicle inspection.

The vision test is required whenever you take a written test.  All tests are given in English and no translators are allowed.

Additional knowledge must be shown in the following areas:

  • Applicants for Class A license - 20 questions on combination vehicles.
  • Applicants driving vehicles with air brakes - 25 questions on air brakes.

Endorsements are required for the following vehicles:

  • Double/triple trailer - 20 questions
  • Tanker - 20 questions
  • Passenger transport - 20 questions
  • Hazardous materials hauling - 30 questions
  • School Bus - 20 questions
Note: For each test, 80% of the questions must be answered correctly to pass.

Failure to show basic knowledge of an air brake system will result in a license restriction limiting the driver to operating a vehicle without an air brake system. Applicants may take the basic knowledge test indefinitely without paying retest fees. However, if the applicant fails, the applicant must wait 24 hours prior to re-testing. The skills test may be taken an unlimited number of times, but the $50.00 skills test fee must be paid to Kentucky State Police each time. The combination, airbrake, and endorsement tests require a $5 re-test fee for each time taken after the initial failure.


Applicants must re-test for the hazardous materials endorsement at renewal of the CDL if it has been more than 2 years since the last test. If transferring into Kentucky an applicant must test in order to keep a hazardous material endorsement.

If a CDL driver surrenders his commercial driving privileges, he has a year to return to the clerk's office and be re-issued the CDL without re-testing.

If the CDL is ever expired for one (1) year or more, the written/vision tests must be taken prior to a new license being issued. An application fee will be charged. 

If applying for a CDL reinstatement, and the commercial privilege has been suspended for one (1) year or more, all tests are required.

What does the road test cover?

Drivers will be required to take this test in the class of vehicle they intend to drive. The test includes a pre-trip inspection, off-road maneuvering, and on-road driving test. The applicant will be required to furnish a vehicle for testing.

After the CDL permit is issued, applicants must wait 14 days before the skill test is administered.  Applicants must call the Kentucky State Police for a skills test appointment. If you passed the written test for air brakes, you will need to skills test in an air brake vehicle, otherwise, you will receive an L restriction.

CDL  Transfers


The state of Kentucky does not transfer commercial instruction permits from other states.

Upon passing those tests, you will be issued a Kentucky commercial instruction permit.

Hazardous Materials Endorsement

If you have a hazardous endorsement, you will be required to take the written hazmat test prior to transferring it to Kentucky. There is a $5 fee to take the written test.

If your hazmat threat assessment will not cover the life of your new Kentucky commercial license, you will be required to undergo a new threat assessment. This will cost $115. In some cases, you may be eligible for a ninety (90) day extension to complete your threat assessment. This will be determined by the CDL  section at the Division of Driver Licensing.​​​​
