Medical certification is a separate document from your CDL license itself

A medical card for a CDL is not part of your driver's license. It is a Medical Examiner's Certificate — a form completed by a certified medical examiner that shows you meet federal health standards to operate a commercial vehicle. The Federal Motor Carrier Safety Administration (FMCSA) requires this certificate before you can legally drive a truck, bus, or other commercial vehicle that falls under CDL rules.

Your state's DMV does not issue this card. A medical examiner on the FMCSA's National Registry performs the exam, fills out the form (MCSA-5875), and gives you the original. You then bring that certificate to your DMV when you explore for or renew your CDL. Without it, your CDL process will be rejected.

The certificate is valid for up to 24 months, depending on what the examiner finds during your physical. Some conditions result in shorter validity periods — as little as 3 or 6 months — which means you will need to repeat the exam sooner.

Key Takeaways

  • A medical card is a certificate from a FMCSA-registered medical examiner, not a document issued by your state DMV.
  • You must have a valid medical certificate before you can obtain or renew a CDL, and the DMV will not process your process without it.
  • The exam checks vision, hearing, blood pressure, diabetes control, and other conditions that affect safe commercial driving.
  • You can find FMCSA-registered examiners through the National Registry search tool on the FMCSA website, and the exam typically costs between $75 and $150.
  • If the examiner finds a medical condition that disqualifies you, you may be able to request a waiver or exemption from the FMCSA, though approval is not may provide.

What the medical examiner checks during the exam

The exam is standardized across all FMCSA examiners. The medical examiner will test your vision (including color blindness and peripheral vision), hearing, blood pressure, and reflexes. They will ask about your medical history, including any surgeries, medications, and chronic conditions like diabetes, heart disease, or sleep apnea.

The examiner will also perform a physical exam — checking your spine, joints, and overall physical condition — because commercial driving requires the ability to control a large vehicle and respond quickly to emergencies. They may order blood work or other tests if your history or physical exam raises concerns.

Certain conditions automatically disqualify you unless you have a waiver from the FMCSA. These include insulin-dependent diabetes, severe hypertension, a history of heart attack or stroke, and untreated sleep apnea. Other conditions may be manageable with medication or monitoring, and the examiner will decide whether you meet the standard.

How to find a FMCSA-registered medical examiner

Not every doctor can perform CDL medical exams. The examiner must be registered with the FMCSA's National Registry. You can search for examiners in your area using the FMCSA's online search tool at fmcsa.dot.gov. The search lets you filter by state, city, or zip code.

Many urgent care clinics, occupational health centers, and independent medical practices employ FMCSA examiners. Some truck driving schools also have examiners on staff or can refer you to one. Call ahead to confirm the examiner is currently registered and to ask about the exam cost and how long the appointment takes.

The exam typically takes 30 to 60 minutes. Bring your current driver's license, proof of address, and a list of any medications you take. If you have a history of a medical condition, bring relevant records or test results so the examiner can review them.

What happens if the examiner finds a disqualifying condition

If the examiner determines you do not meet the medical standard, they will mark your certificate as "not certified" and explain which condition caused the decision. This does not automatically prevent you from getting a CDL — you have options.

You can request a medical waiver or exemption from the FMCSA. The process varies by condition. For some conditions, like insulin-dependent diabetes, the FMCSA has an established waiver program with specific requirements (such as a log of blood sugar readings and a letter from your doctor). For other conditions, you can request an exemption by submitting medical documentation and a statement explaining why you believe you can safely operate a commercial vehicle.

Waiver and exemption requests are reviewed by FMCSA medical staff and can take several weeks or months. Approval is not may provide. During this time, you cannot legally operate a commercial vehicle. If your request is denied, you can reapply after your condition has changed or after you have additional medical evidence to submit.

Renewing your medical certificate before your CDL expires

Your medical certificate has its own expiration date, separate from your CDL. If your certificate expires before your CDL does, you must renew it before you can continue driving commercially. Many drivers let their medical certificate lapse without realizing it, which means they are no longer legally allowed to operate a commercial vehicle even though their CDL is still valid.

You should schedule your renewal exam at least 30 days before your certificate expires. This gives you time to complete the exam and get the new certificate to your DMV if you need to update your CDL record. Some states require you to notify the DMV when your medical certificate is renewed; others do not, but it is good practice to keep your records current.

If your medical certificate expires and you continue to drive commercially, you are operating without the required certification. This can result in fines, out-of-service orders, and potential loss of your CDL.

Medical card costs and what to expect at your appointment

The cost of a medical exam ranges from $75 to $150, depending on the examiner and your location. Some examiners charge more if additional tests (such as blood work or an EKG) are needed. This cost is your responsibility — it is not covered by your state DMV or any federal program.

At your appointment, bring your current driver's license, proof of address, and a list of all medications and supplements you take. If you have a history of a medical condition, bring any relevant medical records, test results, or letters from your doctor. Wear comfortable clothing that allows the examiner to check your blood pressure and perform a physical exam.

The examiner will give you a copy of the completed certificate (MCSA-5875) on the day of the exam. You will need this original or a certified copy when you explore for or renew your CDL at your state DMV. Keep a copy for your records and your employer.

Frequently Asked Questions

Can I use a medical certificate from my regular doctor?

No. Your regular doctor must be registered with the FMCSA's National Registry to perform a CDL medical exam. You can ask your doctor if they are registered, but most primary care physicians are not. You must use an examiner from the FMCSA registry.

What if I have diabetes and take insulin?

Insulin-dependent diabetes is a disqualifying condition under federal standards, but the FMCSA has a waiver program for drivers who meet specific requirements. You will need to provide a log of blood sugar readings, a letter from your doctor confirming your condition is stable, and proof that you monitor your blood sugar regularly. The waiver process takes several weeks.

How long does the medical certificate last?

The certificate is valid for up to 24 months. However, if the examiner finds a condition that requires monitoring, they may issue a certificate valid for only 12 months, 6 months, or even 3 months. The examiner will tell you the validity period when they complete the exam.

What if I fail the medical exam?

Failing the exam means the examiner determined you do not currently meet the medical standard. You can request a waiver or exemption from the FMCSA, or you can address the medical condition (such as lowering your blood pressure with medication) and take the exam again with a different examiner or after a waiting period.

Do I need a medical card to renew my regular driver's license?

No. A medical certificate is only required for a CDL. If you hold a regular driver's license and do not drive commercially, you do not need a medical exam or certificate.
