Who Can Perform a DOT Physical
Not every doctor can perform a DOT physical. Under 49 CFR 391.43(a), the examination must be performed by a medical examiner listed on FMCSA's National Registry of Certified Medical Examiners (NRCME). To get on the registry, an examiner must complete FMCSA-approved training on the physical-qualification standards and pass a certification test, then maintain that certification over time.
Several provider types can become certified medical examiners: physicians (MD/DO), physician assistants, advanced practice nurses, and doctors of chiropractic, among others, depending on state scope-of-practice rules. The practical step for a driver or carrier is simple — confirm the examiner is currently listed on the National Registry before the appointment, because an exam by a non-registered provider does not count toward federal qualification.
Step 1: The Health History
The exam begins with the driver completing the health-history section of the Medical Examination Report. The driver discloses current and past conditions, surgeries, hospitalizations, and medications, and answers questions about specific areas FMCSA cares about — cardiovascular disease, diabetes, seizures and neurological conditions, sleep disorders, vision and hearing, mental-health conditions, and substance use. The driver signs and certifies the history.
This section matters because the examiner builds the rest of the exam around it. A disclosed condition does not automatically disqualify a driver, but it may prompt follow-up questions, a request for records from a treating physician, or a shorter certification period so the condition can be monitored. An inaccurate or incomplete history is a problem in itself, since the certification rests on it.
Step 2: Vitals, Vision, and Hearing
Next the examiner records objective measurements. Blood pressure and pulse are taken — blood pressure is one of the most common reasons a certificate is issued for a shorter period or deferred. The examiner screens vision and hearing against the standards in 49 CFR 391.41(b): distant visual acuity, peripheral field of vision, the ability to recognize traffic-signal colors, and a hearing check (commonly the ability to perceive a forced whisper at five feet, or an audiometric test).
Blood pressure & pulse
Measured against FMCSA guidance; high readings can shorten the card.
Vision
Acuity, peripheral field, and traffic-signal color recognition.
Hearing
Forced-whisper test at five feet or an audiometric test.
General assessment
Height, weight, and overall physical condition recorded.
For the detail on the vision standard and the blood-pressure thresholds, see the related guides on DOT physical vision requirements and DOT physical blood pressure requirements.
Step 3: The Physical Examination
The hands-on portion is a systematic body-system examination. The Medical Examination Report lists the systems the examiner inspects and marks as normal or abnormal, commenting on anything notable. The examiner is applying the physical-qualification standards in 49 CFR 391.41(b) — looking for any condition of a character and extent that would affect the driver's ability to operate a commercial motor vehicle safely.

Step 4: The Urinalysis — A Health Screen, Not a Drug Test
The DOT physical includes a urinalysis, and this is the single most misunderstood part of the exam. The urinalysis at the 49 CFR 391.43 physical is a health screen, not a drug test. On the Medical Examination Report, the examiner records numerical readings for specific gravity, protein, blood, and sugar. These markers are checked because they can reveal underlying conditions — sugar in the urine can flag diabetes, protein or blood can flag kidney disease — that bear on whether the driver can operate safely.
A significant abnormality does not automatically disqualify the driver; it prompts the examiner to comment and may lead to further evaluation. What the physical's urinalysis does not do is screen for marijuana, cocaine, or other drugs. That is a separate test entirely. Drivers routinely conflate the two because both involve a urine sample, but they answer different questions and are governed by different rules. We cover that distinction in depth in the related guide on why the DOT physical urine test is not a drug test.
Two different urine collections
The 391.43 physical urinalysis screens for protein, blood, sugar, and specific gravity — health markers. The DOT drug test under 49 CFR Part 40 is a separate, chain-of-custody-controlled collection sent to an HHS-certified laboratory to screen for five drug classes. Do not assume passing the physical means a drug test was performed, or vice versa.
The Two Forms: MCSA-5875 and MCSA-5876
Every DOT physical produces documentation on two distinct FMCSA forms, and it is worth knowing which is which because they serve different purposes and live in different places.
Medical Examination Report (MER)
Form MCSA-5875The full record of the examination — health history, vitals, body-system findings, and the urinalysis readings. It is the detailed health document. The examiner retains the completed MER on file (FMCSA requires the original be kept by the examiner for at least three years).
Medical Examiner's Certificate (MEC)
Form MCSA-5876Issued only if the driver is qualified. It is the wallet card stating the driver is medically certified and its expiration date. The driver carries it, and the carrier keeps a copy in the driver qualification file as required under Part 391.
The MER is the record; the MEC is the proof
Think of the MCSA-5875 as the exam itself written down, and the MCSA-5876 as the result you can show a roadside inspector or an auditor. For a carrier's files, the certificate (MCSA-5876) and its expiration date are what must be tracked so the driver is never operating on a lapsed card.
The Result and How Long It Lasts
At the end of the exam the examiner reaches a determination: the driver meets the standards and is certified, is certified for a limited period or with a restriction (for example, corrective lenses), or does not meet the standards and is not certified. When a condition needs monitoring, the examiner can issue the certificate for a period shorter than the maximum.
A Medical Examiner's Certificate is valid for up to 24 months, with shorter durations common when a condition such as elevated blood pressure warrants closer follow-up. The certificate shows its own expiration date, and the driver must obtain a new examination before that date — once the card expires, the driver is no longer medically qualified to operate. For the full process of getting and renewing the card, see the related guide on how to get a DOT medical card.
How FileFlo Helps
FileFlo does not perform DOT physicals or issue medical cards — only a certified medical examiner on the National Registry can do that. What FileFlo does is make sure the certificate that comes out of the exam never quietly expires and is always on file.
FileFlo is the records layer for the driver qualification file: it stores each driver's Medical Examiner's Certificate (Form MCSA-5876), tracks its expiration date, and fires alerts well before it lapses. A medical card has a hard expiration with no natural reminder, which is exactly the kind of deadline that slips through spreadsheets. FileFlo keeps it visible and audit-ready.
What FileFlo tracks for medical certification
- Medical Examiner's Certificate (MCSA-5876): Store each driver's MEC in the qualification file with the certificate's expiration date captured.
- Expiration alerts: 60/30/7-day reminders before each medical card expires so no driver runs on a lapsed certificate.
- Fleet-wide medical-card view: See at a glance which drivers are current and which are coming due across the whole fleet.
- Audit-ready export: Export the medical documentation for any driver in minutes when FMCSA or an auditor asks.
Key Takeaways
- Only an NRCME examiner can perform it. 49 CFR 391.43(a) requires a medical examiner on FMCSA's National Registry.
- The exam has four parts: health history, vitals with vision and hearing, a body-system physical, and a urinalysis.
- The urinalysis is a health screen, not a drug test. It checks specific gravity, protein, blood, and sugar — not drugs.
- Two forms come out of it. The MCSA-5875 is the full exam report; the MCSA-5876 is the certificate the driver carries.
- The certificate is valid up to 24 months — sometimes less — and the driver must renew before it expires.
What to Expect at a DOT Physical: FAQ
Answers to common questions about the DOT physical under 49 CFR 391.43, the exam steps, and the MCSA-5875 and MCSA-5876 forms.
Under 49 CFR 391.43(a), the DOT physical must be performed by a medical examiner listed on FMCSA's National Registry of Certified Medical Examiners (NRCME). That includes qualifying physicians, physician assistants, advanced practice nurses, and doctors of chiropractic who have completed the required training and testing and hold an active NRCME certification. You can search the National Registry to confirm an examiner is currently certified before scheduling.
Two forms. The examiner records the entire examination on the Medical Examination Report (MER) Form, MCSA-5875. If the driver is qualified, the examiner issues the Medical Examiner's Certificate (MEC), Form MCSA-5876 — the wallet card that proves medical qualification. The MER (MCSA-5875) is the detailed health record; the MEC (MCSA-5876) is the certificate the driver carries and the carrier keeps in the driver qualification file.
No. The urinalysis at the 49 CFR 391.43 physical is a health screen, not a drug test. The examiner records readings for specific gravity, protein, blood, and sugar to look for signs of underlying conditions such as diabetes or kidney problems. The DOT drug test is a completely separate process under 49 CFR Part 40 that screens for five drug classes. A driver may need both, but the physical's urinalysis does not screen for drugs.
A Medical Examiner's Certificate is valid for up to 24 months, but the examiner can issue it for a shorter period when a condition needs monitoring — for example, a one-year card when blood pressure or another condition warrants closer follow-up. The certificate states its own expiration date. The driver and carrier are responsible for obtaining a new examination before the card expires; an expired certificate means the driver is no longer medically qualified.
The examination under 49 CFR 391.43 covers a health-history review and a hands-on physical: vision and hearing screening, blood pressure and pulse, and an assessment of the body systems — general appearance, eyes, ears, mouth and throat, heart, lungs and chest, abdomen, vascular system, genito-urinary, extremities and joints, spine and musculoskeletal, and neurological function. The examiner is checking for any condition that would affect the driver's ability to operate a commercial motor vehicle safely under the standards in 391.41(b).
No. FileFlo is not a medical examiner, clinic, or laboratory and does not perform examinations or issue certificates — only a certified medical examiner on the National Registry can do that. FileFlo is the records layer: it stores the Medical Examiner's Certificate (Form MCSA-5876), tracks its expiration date, and alerts you before it lapses, so your driver qualification files stay complete and audit-ready. Plans start at $89/month with a 5-day free trial.
Never Let a Medical Card Expire Unnoticed
The DOT physical is performed by a certified medical examiner — but tracking the certificate it produces is on you. FileFlo stores every Medical Examiner's Certificate (MCSA-5876), watches every expiration date, and alerts you 60 days out, so your driver qualification files stay complete and audit-ready every day.
