DOT Medical Examiner’s Certificate: Exam, Cost, and Retesting

To get a DOT medical card, you complete the driver’s section of the Medical Examination Report (Form MCSA-5875), schedule a physical with a provider listed on FMCSA’s National Registry of Certified Medical Examiners, and pass the exam. The examiner then issues your Medical Examiner’s Certificate (Form MCSA-5876) and transmits your results electronically to FMCSA, which forwards them to your state licensing agency so your commercial driver’s license reflects that you’re medically qualified.¹ A standard certificate lasts up to 24 months, though certain conditions cut that window to 12 months, six months, or even three.²

Confirm You Actually Need a Federal Medical Card

When you apply for or renew a CDL, your state asks you to self-certify into one of four operating categories, and only two of them require a federal medical certificate:³

Non-excepted interstate: you cross state lines and don’t qualify for a federal exemption. You need a current federal certificate.
Excepted interstate: you cross state lines only for activities federal rules specifically exempt, such as certain farm operations. No federal certificate needed.
Non-excepted intrastate: you drive only within your home state and must meet that state’s medical rules, which usually mirror the federal ones.
Excepted intrastate: you drive only within your home state doing activities the state has exempted. No certificate needed.

If you do both excepted and non-excepted work, certify to non-excepted. Choosing the wrong category is one of the quicker ways to end up with a surprise CDL downgrade.⁴

One boundary worth naming: FMCSA has no authority to grant medical waivers or exemptions to purely intrastate drivers. All federal exemption programs apply only to interstate commerce, so if you drive within one state only, your state agency sets the rules.⁵

A commercial motor vehicle for these purposes is one with a gross vehicle or combination weight rating of 10,001 pounds or more, designed to carry more than eight passengers for compensation (or more than 15 without compensation), or used to haul hazardous materials in placardable quantities.⁶

Find a Certified Medical Examiner

A physical from your family doctor won’t count unless that provider appears on FMCSA’s National Registry of Certified Medical Examiners. The registry includes physicians, physician assistants, chiropractors, advanced practice nurses, and other clinicians who have completed FMCSA-specific training and passed a federal certification test.⁷ You can search by location, name, or specialty on the FMCSA website.

The examiner’s National Registry number appears on your certificate, and states verify it electronically. If you go to someone not on the registry, the certificate won’t be accepted, no matter what it says.

Prepare Your Paperwork Before the Appointment

You’ll fill out the driver’s portion of the Medical Examination Report (Form MCSA-5875) before the exam. This is where you disclose your full medical history — surgeries, current conditions, and every medication you take. Signing it means you acknowledge that false or omitted information can invalidate the exam and expose you to civil penalties.⁸

Bring these to the appointment:

A full medication list with names, dosages, and prescribing doctors. Include over-the-counter drugs and supplements.
Corrective lenses or hearing aids if you use them for driving. You’ll be tested with them on.
Specialist clearance letters if you have a history of heart surgery, cardiac events, or other significant conditions. The examiner needs documentation from your cardiologist or treating specialist confirming you’re stable enough for commercial driving.
For insulin-treated diabetes, the Insulin-Treated Diabetes Mellitus Assessment Form (MCSA-5870) completed and signed by your treating clinician, plus at least three months of electronic blood glucose self-monitoring records. Your physical has to happen within 45 days of the MCSA-5870 being signed.⁹
Compliance data from your CPAP or other treatment device if you’ve been diagnosed with sleep apnea. Federal rules don’t specifically mandate it, but examiners routinely request treatment compliance records before certifying you.¹⁰

What the Exam Actually Tests

The examiner follows a structured evaluation of vision, hearing, blood pressure, cardiovascular health, and general physical fitness. Not every problem is a fail; some conditions just shorten how long the certificate lasts.

Vision and Hearing

You need at least 20/40 acuity in each eye (with or without correction), at least 70 degrees of horizontal field of vision in each eye, and the ability to distinguish standard red, green, and amber traffic signals.¹¹ Drivers who can’t meet the standard in one eye may qualify under an alternative vision standard that replaced the old Federal Vision Exemption Program in 2022, but that pathway requires annual recertification rather than the standard two years.¹²

For hearing, you must perceive a forced whisper at five feet in your better ear, or pass an audiometric test showing no worse than a 40-decibel average hearing loss at 500, 1,000, and 2,000 Hz. Hearing aids are allowed for the exam and for driving.¹¹

Blood Pressure

High blood pressure is the single most common reason drivers walk out with a short-term certificate instead of the full two years. The FMCSA Medical Examiner’s Handbook translates the regulation into staged thresholds:¹³

Below 140/90: full two-year certificate.
Stage 1 (140–159/90–99): one-year certificate.
Stage 2 (160–179/100–109): one-time three-month certificate to start or adjust medication, then one year if controlled to 140/90 or below.
Stage 3 (180+/110+): not certifiable at any duration until controlled. Once controlled, six-month certifications.

If your numbers are borderline going in, getting them down before the exam saves you the cost of more frequent visits.

Urinalysis and Physical Exam

A urine test is part of every DOT physical. The examiner screens for protein, blood, and sugar to catch kidney problems, diabetes, and other underlying conditions. This is not a drug test — DOT drug testing is a separate program your employer administers.¹⁴

The hands-on portion covers neurological, respiratory, musculoskeletal, and abdominal systems, checking for tremors, muscle weakness, hernias, and any condition likely to cause sudden loss of consciousness or vehicle control.¹¹

Insulin-Treated Diabetes

Insulin-treated drivers can qualify, but the maximum certificate is 12 months, not 24. To get that full year you need at least three months of electronic blood glucose self-monitoring records from a glucometer that stores readings with dates and times. Without those records, the certificate is limited to three months. A severe hypoglycemic episode — one requiring help from others or involving loss of consciousness — bars you from driving until your clinician confirms the cause has been addressed and completes a new MCSA-5870.⁹

Disqualifying Medications

Any Schedule I controlled substance is an automatic disqualifier, and so is any anti-seizure medication used to prevent seizures. You also can’t use a controlled substance or prescription drug without a valid prescription from a licensed practitioner.¹⁵ For other medications that could affect driving, the examiner has discretion. A written statement from your prescribing doctor saying you’re safe to drive on the medication helps, but doesn’t obligate the examiner to certify you.

After You Pass

Once the examiner determines you’re qualified, they issue your Medical Examiner’s Certificate on Form MCSA-5876 and give you a copy.¹ Certified examiners must upload results to the National Registry by midnight of the next calendar day.¹⁶ As of June 2025, FMCSA transmits that data electronically to your state licensing agency, so in most cases you no longer need to hand-carry paperwork to the DMV.³

Keep the physical certificate accessible anyway. Your employer needs a copy for your driver qualification file, and enforcement officers may ask to see it at inspections. Confirming that your state has actually posted the update to your CDL record is worth a two-minute check; administrative gaps happen, and a roadside stop is a poor place to find one.

If your certificate lapses, your state must mark your CDL “not-certified” and complete a downgrade within 60 days.¹⁷ Schedule your next exam well before the expiration date, not the week of.

What It Costs

DOT physicals generally run between $50 and $200 out of pocket, depending on the provider and location. Chiropractors and urgent care clinics tend to be cheaper; private physician offices charge more. Health insurance usually doesn’t cover the exam because it’s an employment requirement, not a diagnostic visit. Follow-up tests the examiner orders — bloodwork, a sleep study, a specialist consult — are extra. Some employers reimburse the fee, so check your company’s policy before paying.

If You Don’t Pass

Failing the physical isn’t always permanent. When the examiner needs more information — additional test results, a specialist report, documentation from your treating provider — they can place you in “determination pending” status. That gives you up to 45 days to produce what’s needed. If the examiner doesn’t update your status in the National Registry within those 45 days, the exam becomes invalid and you start over.¹³ Pending status does not extend your current certificate. If it has expired, you’re grounded until a final determination.

If you think the examiner got it wrong, the practical route for most drivers is a second exam with a different certified medical examiner, especially if your condition has changed or the first examiner missed something. A formal dispute process exists under 49 CFR 391.47, but it treats you as disqualified while FMCSA reviews, and the agency publishes no guaranteed timeline.¹⁸

Some drivers who can’t meet a specific physical standard qualify for a federal exemption. FMCSA runs a hearing exemption application process that requires your three-year driving record, a copy of your certificate noting the hearing deficiency, and a release for medical information. Applications are published in the Federal Register for a 30-day public comment period.¹⁹ Drivers with a limb loss or impairment can pursue a Skill Performance Evaluation certificate, which requires a medical evaluation from a board-certified physiatrist or orthopedic surgeon, a road test, your three-year driving record, and proof you can perform precision and power grip with each hand. SPE certificates last up to two years and must be renewed 30 days before expiration.²⁰
