Health requirement
DOT Medical Card / DOT Physical
Before the Service Oklahoma issues your CDL, you must pass a DOT physical — a medical exam performed by a certified examiner that confirms you're fit to operate a commercial vehicle.
The examiner checks your vision, hearing, blood pressure, and general health, then issues a Medical Examiner's Certificate (often called a "DOT medical card"). You file this with the Service Oklahoma, and it must be renewed periodically to keep your CDL valid.
- Required for most CDL applicants before a permit or license is issued
- Performed by an examiner listed on the FMCSA National Registry
- Results in a Medical Examiner's Certificate (DOT medical card)
- Must be kept current — typically renewed every 24 months or sooner

Frequently Asked Questions
Common questions from CDL applicants in Oklahoma.
Do I need Entry-Level Driver Training (ELDT) in Oklahoma?
Yes for most first-time applicants. Complete ELDT from an FMCSA-registered provider before the skills test (Service Oklahoma recommends finishing it before the written test). Bring your completion certificate for hazmat or skills testing. Prior CDL holders may be exempt; ELDT is not required solely to remove an air-brake or automatic-transmission restriction.
Do I need a DOT medical certificate for a CDL in Oklahoma?
Only if you self-certify as Non-Excepted Interstate (NI). Service Oklahoma requires a Medical Examiner's Certificate from an FMCSA-certified examiner for NI licensing. Excepted Interstate (EI), Excepted Intrastate (EA), and Non-Excepted Intrastate (NA) do not require a DOT medical card for licensing, though you may still need one to operate under employer or other rules.
What do I need to bring to apply for a CDL permit in Oklahoma?
Bring proof of identity, proof of lawful presence, a valid Oklahoma Class D license, one proof of address (two for REAL ID), and your Social Security number (physical card not required). Immigration applicants need a valid I-551 or a foreign passport with a valid I-94. Bring an ELDT completion certificate for hazmat or before skills testing. Vision and written tests are taken together at a Service Oklahoma Licensing Office.
Do I need a background check for a hazmat endorsement in Oklahoma?
Yes. Complete the TSA Hazardous Materials Endorsement Threat Assessment (background check and fingerprinting), finish hazmat ELDT if you are a first-time applicant, and pass the hazmat knowledge test. Start the TSA process early through the federal hazmat endorsement program.
How long must I hold an Oklahoma CLP before the skills test?
Hold your Commercial Learner's Permit for 14 full days before the drive test. You may take the skills test on the 15th day after the permit is issued. Schedule online through Save Your Spot (Drive test - Commercial Driver License) or with an approved third-party examiner.
How much does an Oklahoma CDL cost?
For a 4-year credential, Class A totals $81.50 ($25 application + $56.50 credential), Class B $71.50, and Class C $61.50. Eight-year options are $138.00 (A), $128.00 (B), and $108.00 (C). Adding a motorcycle endorsement for the first time adds a $4 application fee.
What changed about Oklahoma's CDL skills test?
Oklahoma updated to the modernized CDL skills test model. Vehicle inspection and basic control skills portions differ from the older format, while standards for readiness stay high. Service Oklahoma does not supply a test vehicle — bring your own insured, registered CMV.
If I fail part of the Oklahoma skills test, do I retake everything?
No. If you pass one section (pre-trip, basic controls, or road test) but fail another, you keep credit for the passed section and only retest the failed part. Section results are valid only for the duration of your current CLP.
Does PrepCDL cover Oklahoma?
Yes. PrepCDL includes state-specific study guides and practice questions aligned with the Oklahoma CDL manual, plus prep for every class and endorsement.
