How to Get Your CDL in Kentucky The process of getting your CDL isn’t complicated — it’s particularly true in Kentucky since they offer an online system that can make it convenient for applicants. That said, you’ll need to go through two stages:

  • Your commercial learner’s permit (CLP)
  • Your commercial driver’s license (CDL)

Here’s what you have to do for each stage. How to Get Your Kentucky CLP Here are the steps to getting your CLP in Kentucky:

  1. Ensure you meet all the requirements in the section above.
  2. Decide on the CDL class you need.
  3. Create an account on the Kentucky Online Gateway.
  4. Once you have it set up, fill out the online application form. You will get a confirmation email that you’ve submitted your application.
  5. You can use the same portal to complete your self-certification and upload your medical certificate.

NOTE: If you prefer to complete a paper application, download and fill out the Commercial Driver License Application and Commercial Driver License Self-Certification forms. You must then send them and your Medical Examiner’s Certificate by mail to this address:

  • Division of Driver Licensing
  • 200 Mero St.
  • Frankfurt, KY 40622

You will receive a confirmation letter if the office accepts your documents.

  1. Schedule a CDL written test appointment with the Kentucky State Police.
  2. Pass a vision test.
  3. Pass the written portion of the CDL exam.
  4. Go to your local Driver Licensing Regional Office.
  5. Submit a 10-year driving record and a valid ID.
  6. Pay the application fees:
  • If applying for a Class B or Class C CDL with a P or S endorsement – $9
  • If applying for any other CDL – $24
  • CLP fee – $11
  1. Get your CLP. And there you have it — the steps to getting your CLP. Remember that, just like a learner’s permit, a CLP comes with restrictions. Although you can already drive a CMV on public roads, a licensed commercial driver at least 21 years old must always be with you.
