The Oklahoma CDL permit test

You take it in person at a Service Oklahoma Licensing Office: the general knowledge test, plus a test for your class and each endorsement, with the vision test at the same visit. The questions come from Service Oklahoma's CDL Driver Manual, dated March 2025. You need an Oklahoma Class D license first, and after the CDL permit test in Oklahoma you hold your commercial learner permit (CLP) 14 full days before the skills test.

Which class do you need?

  • Class A: a combination with a combined weight rating of 26,001 pounds or more, towing a trailer rated over 10,000 pounds.
  • Class B: a single vehicle rated 26,001 pounds or more, towing a trailer rated under 10,001 pounds.
  • Class C: a smaller vehicle that needs a hazmat or passenger endorsement, such as one built for 16 or more people including the driver.

How does the CDL permit test in Oklahoma work?

  1. Study the CDL Driver Manual for the general knowledge test and the class and endorsement tests you need.
  2. Bring proof of identity and lawful presence, your Class D license, proof of residency (two for REAL ID) and your Social Security number. The manual says you must be able to read and understand English.
  3. Pass the written tests and the vision test at a Service Oklahoma Licensing Office. You get your CLP and a DL18 CT form showing your score.
  4. Finish Entry-Level Driver Training with a provider on FMCSA's Training Provider Registry before the skills test, unless an exception applies.
  5. Hold the CLP 14 full days. A licensed driver 21 or older with the right class and endorsements must ride with you.
  6. Take the skills test, about two hours: a pre-trip inspection, basic control and a road test. You bring the vehicle. Third-party examiners also give it and set their own rates.

Is there an Oklahoma CDL practice test?

Service Oklahoma's CDL page points you to the CDL Driver Manual, not a practice test, and Service Oklahoma's free practice test in the Driver Study Hub is for the Standard Class D written test. Study the manual's general knowledge section, then the sections for your class and each endorsement. Some apps, such as Driving-Tests.org, have Oklahoma CDL sections, but their questions are their own, not Service Oklahoma's.

Rules that catch people out

  • The CLP is valid for 180 days and can be renewed for another 180, the Driver Manual says. Your skills test results only count while the CLP is valid.
  • Pass a section of the skills test and you keep the credit, so you only retest the sections you failed.
  • Since February 17, 2026, Service Oklahoma no longer accepts paper medical examiner's certificates. Your certified medical examiner submits it through FMCSA's National Registry.
  • A hazmat endorsement needs a federal background check and fingerprints through the TSA.
