DOT Physical Guidelines Medical Examiners Must Follow

Last reviewed: July 2026

Certified Medical Examiners must follow the Federal Motor Carrier Safety Regulations, complete the required medical history, testing, physical examination, and documentation, make an independent qualification decision, issue a certificate only when the driver qualifies, and report every examination through the National Registry. FMCSA’s Medical Examiner’s Handbook and advisory criteria help examiners apply the rules, but guidance does not replace the binding regulations.

Key Takeaways

  • The binding physical qualification standards appear primarily in 49 CFR 391.41 through 391.49.
  • The Medical Examiner’s Handbook provides guidance and recommendations; it does not create an automatic rule for every diagnosis or situation.
  • Medical examiners must complete the entire examination even after identifying a potentially disqualifying condition.
  • FMCSA has no standalone BMI or neck-circumference measurement that automatically passes or fails a driver.
  • The required urinalysis is not a DOT drug test. It records specific gravity, protein, blood, and glucose.
  • Every started examination, including an incomplete examination or a determination that the driver does not qualify, must be reported to the National Registry by the applicable deadline.

Who Sets the DOT Physical Guidelines?

The Federal Motor Carrier Safety Administration, commonly called FMCSA, administers the federal physical qualification standards for interstate commercial motor vehicle drivers. Medical examiners must distinguish binding regulations from advisory material when applying those standards.

Hierarchy of DOT physical rules and guidance
Source Purpose How the examiner should use it
49 CFR Part 390, Subpart D Establishes National Registry certification, training, testing, continued-listing, and compliance requirements for medical examiners. Treat these requirements as binding federal regulations.
49 CFR 391.41 through 391.49 Establishes driver physical qualification standards, examination requirements, alternative standards, and variance pathways. Base the qualification decision on the applicable regulatory standard.
Appendix A to Part 391 Provides medical advisory criteria that assist with interpretation of several standards. Use the criteria as federal guidance while recognizing that they do not replace the regulation.
Medical Examiner’s Handbook 2024 Edition Provides current FMCSA recommendations, explanations, clinical considerations, forms guidance, and examples. Use the Handbook to support informed case-by-case judgment.
FMCSA forms and National Registry instructions Establish required data fields, determinations, electronic reporting, and administrative procedures. Use the current version of each applicable form and follow current National Registry instructions.
State requirements May establish intrastate standards or variances for drivers who operate only within that State. Do not apply an intrastate variance to interstate operation.

Examiners should use the current 49 CFR Part 391, Subpart E, the Medical Advisory Criteria in Appendix A, and FMCSA’s Medical Examiner’s Handbook 2024 Edition.

Who May Perform a DOT Physical?

An interstate DOT physical generally must be completed by a medical examiner who is currently listed in FMCSA’s National Registry of Certified Medical Examiners.

To qualify for certification, the medical professional must:

  • Be licensed, certified, or registered under applicable State law to perform physical examinations.
  • Register with the National Registry.
  • Complete an FMCSA-compliant medical examiner training program.
  • Pass the National Registry Medical Examiner Certification Test.
  • Complete FMCSA’s validation and certification process.

Depending on State law, eligible professionals may include physicians, osteopathic physicians, physician assistants, advanced practice nurses, doctors of chiropractic, and other qualified medical professionals.

How must examiners maintain their certification?

Certified Medical Examiners must continue to satisfy FMCSA and professional-licensure requirements. Federal continued-listing rules include:

  • Maintaining the professional authority to perform physical examinations.
  • Reporting changes in National Registry registration information within the required timeframe.
  • Completing FMCSA periodic training between years four and five.
  • Completing periodic training and passing the certification test between years nine and ten.
  • Cooperating with FMCSA monitoring, audits, and record requests.
  • Following the examination, documentation, and reporting requirements in Part 391.

Healthcare professionals pursuing initial certification can review TeamCME’s guide on how to become a DOT Certified Medical Examiner.

What Process Must a Medical Examiner Follow During a DOT Physical?

The examiner must complete a standardized physical qualification process rather than a general wellness visit. The examination should connect the driver’s health history, objective findings, treatment, functional ability, and commercial-driving demands.

  1. Verify the driver’s identity.
    Record the form of photo identification used to verify the driver.
  2. Confirm the type of examination.
    Determine whether the examination concerns federal interstate qualification or State intrastate requirements.
  3. Review the completed health history.
    Discuss every “yes” and “not sure” answer, identify omitted information, and compare the medication list with the reported conditions.
  4. Review relevant supporting records.
    Evaluate specialist reports, treatment records, required FMCSA assessment forms, prior procedures, medication information, and variance documents.
  5. Complete the required testing.
    Record pulse, height, weight, blood pressure, urinalysis, vision, and hearing results.
  6. Complete the physical examination.
    Evaluate every body system listed on Form MCSA-5875 and explain abnormal findings.
  7. Evaluate the applicable qualification standards.
    Consider whether each condition, treatment, limitation, or medication could interfere with safe commercial driving.
  8. Complete the entire examination.
    Do not stop after identifying one potentially disqualifying condition. Other findings may be relevant to a future examination, exemption, or variance.
  9. Make an independent determination.
    Treating clinicians and specialists may provide information, but the Certified Medical Examiner makes the final federal qualification decision.
  10. Document and explain the result.
    Record the correct outcome, restrictions, monitoring period, variance, or reason the standards were not met.
  11. Report the examination.
    Submit the result through the National Registry even when the driver does not qualify or the examination is incomplete.

What Tests and Examination Components Are Required?

Form MCSA-5875 identifies the required testing and body systems. Additional testing is not automatically required for every driver; it should be requested when the history, examination, regulation, or condition-specific guidance supports it.

Required DOT physical examination components
Component What the examiner records or evaluates
Identity and driver information Identity document, driver’s-license information, CDL/CLP status, contact details, and relevant certification history.
Health history Medical conditions, surgeries, hospitalizations, symptoms, prior certification issues, substance history, sleep disorders, and other required responses.
Medication review Prescription drugs, over-the-counter products, herbal remedies, supplements, dosage, side effects, and the underlying condition.
Pulse, height, and weight Objective measurements entered in the testing section of the form.
Blood pressure Systolic and diastolic readings, repeat measurement when appropriate, treatment history, complications, and medication tolerance.
Urinalysis Specific gravity, protein, blood, and glucose or sugar.
Vision Visual acuity in each eye and both eyes, field of vision, traffic-signal color recognition, corrective lenses, and alternative-standard documentation when applicable.
Hearing Forced-whisper or audiometric result, better ear, hearing-aid use, and exemption documentation when applicable.
General appearance and skin Observable abnormalities or findings that may relate to safe operation.
Eyes, ears, mouth, and throat Relevant abnormalities beyond the numerical vision and hearing tests.
Cardiovascular and vascular systems Findings relevant to syncope, dyspnea, collapse, heart failure, circulation, and safe control of a commercial vehicle.
Lungs and chest Respiratory findings, symptoms, oxygenation concerns, and functional limitations.
Abdomen and genitourinary system Relevant findings, including hernias where applicable.
Back, spine, extremities, and joints Strength, motion, limb loss or impairment, grasping, mobility, pain, and ability to perform normal commercial-driving tasks.
Neurological system, reflexes, and gait Coordination, strength, consciousness risk, balance, gait, cognition, and other relevant neurological findings.

What Are the DOT Physical Blood-Pressure Guidelines?

The federal regulation asks whether the driver has high blood pressure likely to interfere with safe operation. FMCSA’s advisory criteria provide staged blood-pressure guidance for certification decisions.

FMCSA blood-pressure guidance for medical certification
Reading or category General certification guidance
139/89 or below A driver may qualify for up to two years when no other condition or monitoring need limits the certificate. A known or treated history of hypertension may justify more frequent monitoring.
Stage 1: 140–159 systolic and/or 90–99 diastolic The driver may generally receive a one-year certificate. At later examinations, a one-time three-month certificate may be considered when the reading remains above 140/90 but below 160/100.
Stage 2: 160–179 systolic and/or 100–109 diastolic A one-time three-month certificate may be issued to begin or adjust treatment. If the pressure is reduced to 140/90 or below and treatment is tolerated, the driver may be certified for one year.
Stage 3: approximately 180/110 or higher The driver should not be qualified, even temporarily, until the pressure is reduced to 140/90 or below and treatment is tolerated. Six-month certification intervals may then apply.

Readings above 139/89 should be confirmed with another measurement later in the examination. The examiner should also consider target-organ damage, secondary hypertension, treatment effectiveness, orthostatic symptoms, somnolence, syncope, and other medication effects.

This staged framework is advisory guidance. The examiner’s underlying regulatory task remains determining whether the driver has high blood pressure likely to interfere with safe operation.

TeamCME’s driver resource on FMCSA blood-pressure guidelines provides a driver-facing explanation.

What Are the DOT Physical Vision Requirements?

Under the standard federal rule, a driver generally must meet requirements for distant acuity, binocular acuity, horizontal field of vision, and traffic-signal color recognition.

The ordinary vision standard generally requires:

  • At least 20/40 distant visual acuity in each eye, with or without correction.
  • At least 20/40 binocular distant visual acuity.
  • A field of vision of at least 70 degrees in the horizontal meridian in each eye.
  • The ability to recognize standard red, green, and amber traffic-signal colors.

If corrective lenses are needed to meet the standard, the examiner should record the corrective-lens restriction.

What if the worse eye does not meet the ordinary vision standard?

A driver may qualify through the alternative vision standard in 49 CFR 391.44 when the worse eye does not meet the ordinary acuity or field requirement. The driver must obtain a completed Vision Evaluation Report, Form MCSA-5871, from an ophthalmologist or optometrist.

The Certified Medical Examiner must begin the physical qualification examination within 45 days of the eye specialist signing the form. The eye specialist provides the vision evaluation, but the Certified Medical Examiner makes the final qualification decision.

What Are the DOT Hearing Requirements?

A driver may satisfy the federal hearing standard by passing either the forced-whisper test or the audiometric standard in the better ear, with or without a hearing aid.

The driver generally must:

  • Perceive a forced whispered voice in the better ear from at least five feet; or
  • Have an average hearing loss in the better ear of no more than 40 decibels at 500, 1,000, and 2,000 Hz during properly calibrated audiometric testing.

If the driver does not pass the forced-whisper test, the examiner may use audiometric testing. Passing while using a hearing aid results in a hearing-aid restriction.

A driver who cannot meet the standard may investigate a federal hearing exemption. An exemption is different from meeting the standard with a hearing aid, and the examiner should not mark both statuses as though they were the same.

Is There a BMI or Neck-Size Requirement for a DOT Physical?

No federal regulation establishes a standalone BMI or neck-circumference measurement that automatically passes, fails, or disqualifies a driver.

Body mass index, obesity, and large neck size may be relevant as possible risk factors for obstructive sleep apnea. However, FMCSA’s 2024 Handbook recommends considering multiple risk factors rather than relying on one measurement.

Potential risk factors may include:

  • High BMI or obesity.
  • Large neck size.
  • Loud snoring.
  • Witnessed apneas.
  • Daytime sleepiness.
  • A small airway.
  • Hypertension.
  • Cardiovascular disease.
  • Stroke or diabetes history.
  • Other relevant comorbidities.

The Federal Motor Carrier Safety Regulations do not establish one mandatory sleep-apnea screening method, BMI threshold, neck-size threshold, diagnostic test, treatment method, waiting period, certification duration, or PAP-compliance percentage.

An examiner who identifies multiple risk factors should consider whether further evaluation is appropriate. BMI or neck size alone should not be represented as an automatic federal failure rule.

When Are Stress Tests, Spirometry, or Other Tests Required?

Stress testing, spirometry, imaging, laboratory testing, and specialist consultation are not universal components of every DOT physical. Additional testing should be connected to the driver’s history, symptoms, findings, condition, or applicable condition-specific guidance.

Are stress tests required for every driver?

No. FMCSA does not require a routine cardiac stress test for every driver.

An exercise tolerance test, echocardiogram, or other cardiac study may be relevant when:

  • The examiner identifies a possible undiagnosed cardiac condition.
  • The driver has known coronary heart disease.
  • The driver reports symptoms such as exertional chest discomfort, unexplained shortness of breath, syncope, or reduced exercise capacity.
  • The driver has undergone a procedure or event for which current FMCSA guidance recommends follow-up testing.
  • A cardiologist’s assessment is needed to establish current function and stability.

Test results should be interpreted in the context of the applicable cardiovascular standard. A specialist recommendation supplements the examination but does not replace the medical examiner’s decision.

Must every smoker over age 35 undergo spirometry?

No. The current federal rules and 2024 Handbook do not establish a blanket spirometry requirement for every smoker over age 35.

Pulmonary function testing may be appropriate when respiratory history, symptoms, resting breathing difficulty, physical findings, surgery, chest-wall impairment, chronic lung disease, or functional concerns require further assessment.

What is required after surgery?

FMCSA does not impose one universal waiting period for every type of surgery. The examiner should consider:

  • The underlying reason for the procedure.
  • Whether healing is complete.
  • Pain and pain-medication effects.
  • Strength, mobility, and functional capacity.
  • Risk of recurrence or sudden impairment.
  • Specialist recommendations.
  • Condition-specific regulations and guidance.

Some cardiac, neurological, orthopedic, abdominal, or other procedures may have condition-specific recommendations. The examiner should document the basis for the qualification decision rather than applying a generic post-surgery rule.

How Should Medical Examiners Evaluate Medications and Substance Use?

The examiner must evaluate the medication, the condition being treated, treatment stability, dosage, side effects, interactions, and possible effects on safe commercial driving.

Controlled medications

Under 49 CFR 391.41(b)(12), a driver using a non-Schedule I controlled substance may qualify when the prescription exception is satisfied. The prescribing practitioner must:

  • Be legally authorized to prescribe the substance.
  • Be familiar with the driver’s medical history.
  • Advise that the substance will not adversely affect the driver’s ability to operate a commercial vehicle safely.

The examiner may obtain written information from the prescriber, including through the optional 391.41 CMV Driver Medication Form, MCSA-5895. The prescribing clinician’s statement does not require the examiner to certify the driver. The final decision remains with the Certified Medical Examiner.

Is the DOT physical urinalysis a drug test?

No. The required physical-exam urinalysis records specific gravity, protein, blood, and glucose or sugar. It is not the federal DOT workplace drug test conducted under 49 CFR Parts 40 and 382.

A medical examiner may request a non-DOT drug or alcohol test when signs, history, or inconsistent information make additional evidence relevant to the medical qualification decision. That examiner-requested test remains separate from an employer’s DOT-regulated drug and alcohol testing program.

Which FMCSA Forms Must Medical Examiners Use?

Principal FMCSA medical examination forms
Form Purpose Key requirement
MCSA-5875 — Medical Examination Report Records driver information, health history, testing, physical findings, and the qualification determination. Complete it for every physical qualification examination and retain the original record for at least three years.
MCSA-5876 — Medical Examiner’s Certificate Documents that the driver was found physically qualified. Issue it only when the driver qualifies. Retain a copy or electronic version for at least three years.
MCSA-5850 — CMV Driver Medical Examination Results Electronically reports the examination result to FMCSA. Report every started examination, including incomplete and not-qualified results, through the National Registry.
MCSA-5870 — Insulin-Treated Diabetes Mellitus Assessment Provides information from the treating clinician for a driver using insulin. The examiner must begin the physical qualification examination within 45 days of the treating clinician signing the form.
MCSA-5871 — Vision Evaluation Report Provides the specialist evaluation required for the alternative vision standard. The examiner must begin the physical qualification examination within 45 days of the ophthalmologist or optometrist signing the form.
MCSA-5895 — CMV Driver Medication Form Optional tool for obtaining information from the prescribing practitioner. Use when medication information would assist the qualification decision; it does not transfer the final decision to the prescriber.

Use the current forms available through FMCSA’s medical applications and forms page rather than saving an old version indefinitely.

What Qualification Outcomes May a Medical Examiner Record?

A DOT physical does not produce only a simple pass-or-fail result. Form MCSA-5875 supports several outcomes.

Medical examiner determination options
Outcome When it is used
Meets standards; two-year certificate The driver meets the applicable standards and no condition requires more frequent monitoring.
Meets standards; periodic monitoring required The driver qualifies but requires a shorter certificate, such as three months, six months, one year, or another supported period.
Does not meet standards The driver currently fails to meet one or more applicable standards and no current variance or alternative qualification pathway supports certification.
Determination pending The examiner needs clarification or additional information before making the final decision. The pending period cannot exceed 45 days.
Incomplete examination The examination could not be completed. The result must still be reported.
Qualified with a restriction, variance, exemption, or SPE certificate The driver qualifies subject to the applicable corrective-lens or hearing-aid restriction, medical variance, exemption, alternative standard, or Skill Performance Evaluation certificate.

Can an examiner issue a certificate while waiting for records?

The examiner should not issue a certificate based on an unsupported assumption that missing records will later confirm qualification. When the available information is insufficient, the examiner may use determination pending when that option is appropriate or require a new examination.

A determination-pending examination must be resolved within 45 days. It does not extend an expiring Medical Examiner’s Certificate.

Can an employer influence the decision?

No. A motor carrier may pay for the examination or request operational information, but the examiner must make an independent medical qualification decision.

An examiner should not shorten, extend, restrict, or approve a certificate merely because a carrier asks for a particular outcome.

What Are the Reporting and Recordkeeping Requirements?

Report every examination by the next calendar day

Medical examiners must report the result of every physical qualification examination through their individual National Registry account by midnight, local time, on the next calendar day after the examination.

The reporting requirement includes examinations in which the driver:

  • Qualifies for a certificate.
  • Receives a shorter certificate.
  • Does not meet the standards.
  • Is placed in determination pending.
  • Does not complete the examination.

Retain records for at least three years

The examiner must retain:

  • The original paper or electronic MCSA-5875.
  • A copy or electronic version of MCSA-5876 when a certificate was issued.
  • Attachments that form part of the examination record.
  • Applicable assessment forms, specialist information, and variance documentation.

The records must remain accessible even when a clinic or centralized records department stores them on the examiner’s behalf.

Respond to authorized record requests

Records related to the examination must be made available to an authorized FMCSA or other qualified enforcement representative within 48 hours after an applicable request.

Provide records appropriately

The driver may request a copy of the Medical Examination Report regardless of who paid for the examination. The complete report is not automatically sent to the employer merely because the employer paid for the examination.

The Medical Examiner’s Certificate and qualification status are handled according to the applicable federal, State, National Registry II, and employer-record requirements.

Current National Registry II note

Temporary policy in effect on this page’s review date: FMCSA’s current exemption allows interstate CDL holders, CLP holders, and motor carriers to rely on a paper Medical Examiner’s Certificate for up to 60 days after issuance. The exemption is effective from April 11 through October 11, 2026.

FMCSA also recommends that medical examiners continue issuing drivers a paper MCSA-5876 in addition to submitting results electronically until further notice. This temporary policy does not remove the examiner’s next-calendar-day electronic reporting obligation.

Because the exemption is time-sensitive, examiners should review the current National Registry II Learning Center before relying on this section after October 11, 2026.

How Should Examiners Use Specialist Reports?

Specialist reports help the examiner understand diagnosis, treatment, functional status, stability, prognosis, recurrence risk, and medication effects. They do not transfer the federal qualification decision to the specialist.

The examiner should request focused information that answers the safety question. For example:

  • Is the condition stable?
  • Is treatment effective and tolerated?
  • Are symptoms present that could cause loss of control, impaired alertness, syncope, dyspnea, collapse, or another safety risk?
  • What objective testing supports the opinion?
  • What follow-up is planned?
  • Could the condition or treatment affect the physical and cognitive demands of commercial driving?

A generic “cleared to drive” note may not provide enough information to support the examiner’s decision.

Common DOT Physical Compliance Errors

Using one BMI or neck-size cutoff as an automatic failure rule

FMCSA does not establish an automatic federal BMI or neck-size disqualification. Evaluate multiple risk factors and the effect of any diagnosed condition.

Treating the Handbook as though every recommendation were a regulation

The Handbook assists with application of the rules. Clearly distinguish mandatory standards from guidance and case-by-case considerations.

Stopping the examination after finding one disqualifying condition

Complete the entire examination. Other findings may affect future qualification, treatment, exemptions, or the accuracy of the examination record.

Using the standard urinalysis as a drug screen

The required urinalysis records specific gravity, protein, blood, and glucose. Document any separately requested non-DOT drug or alcohol test as a distinct process.

Issuing a certificate before required records are available

Do not issue a certificate merely because the driver expects a specialist to provide favorable information later.

Allowing a carrier or treating clinician to make the decision

Consider relevant recommendations, but retain independent responsibility for the federal qualification determination.

Failing to explain a shortened certificate

Document the condition or monitoring need that supports a shorter certification period.

Failing to report an incomplete or not-qualified examination

Every started examination must be reported through the National Registry, regardless of the result.

Using outdated forms or guidance

Confirm the current form version, Handbook edition, eCFR text, National Registry notice, and temporary exemption before relying on saved office materials.

What Should Medical Examiners Do Next?

  1. Confirm that your professional license and National Registry information are current.
  2. Complete all periodic training and testing by the applicable deadline.
  3. Replace old forms and outdated handbook copies.
  4. Create a standardized workflow based on MCSA-5875.
  5. Verify that staff understand the difference between required tests and condition-specific testing.
  6. Audit how determination-pending examinations are tracked.
  7. Confirm that every examination is reported by midnight on the next calendar day.
  8. Verify that records remain accessible for at least three years.
  9. Review the current National Registry II instructions.
  10. Document the medical and regulatory basis for each qualification decision.

Providers preparing for initial certification can review TeamCME’s NRCME certification training. Examiners approaching renewal can review NRCME recertification training.

Frequently Asked Questions

What guidelines must DOT medical examiners follow?

DOT medical examiners must follow the applicable Federal Motor Carrier Safety Regulations, use current FMCSA forms, complete the required history, testing, and physical examination, make an independent qualification decision, document the result, retain the records, and report every examination through the National Registry. The Medical Examiner’s Handbook and Appendix A provide guidance for applying the regulations.

Is there a BMI limit for a DOT physical?

No. FMCSA does not establish a standalone BMI cutoff that automatically passes or fails a driver. A high BMI may be considered with other obstructive sleep apnea risk factors, symptoms, medical conditions, and examination findings.

Is there a DOT physical neck-size requirement?

No. FMCSA does not establish one neck-circumference measurement that automatically requires a sleep study or disqualifies a driver. Neck size may be considered as one of several obstructive sleep apnea risk factors.

What blood pressure is required for a DOT physical?

A reading of 139/89 or below may support certification for up to two years when no other condition requires monitoring. FMCSA guidance generally allows one year for Stage 1 hypertension, a one-time three-month certificate for Stage 2 treatment, and no certification for Stage 3 hypertension until the pressure is controlled and treatment is tolerated.

What are the DOT physical vision requirements?

The ordinary federal standard generally requires at least 20/40 distant visual acuity in each eye, at least 20/40 binocular acuity, a horizontal field of at least 70 degrees in each eye, and recognition of standard red, green, and amber traffic-signal colors. An alternative vision standard may apply when the worse eye does not meet the ordinary acuity or field requirement.

What are the DOT hearing-test requirements?

A driver generally must perceive a forced whispered voice from at least five feet in the better ear or have an average hearing loss of no more than 40 decibels at 500, 1,000, and 2,000 Hz in the better ear. The standard may be met with a hearing aid, or the driver may investigate a federal hearing exemption.

Is a drug test part of the DOT physical?

No. The required physical-exam urinalysis records specific gravity, protein, blood, and glucose. DOT-regulated workplace drug testing is a separate process. A medical examiner may request a non-DOT drug test when it is relevant to the medical qualification decision.

Does every driver need a cardiac stress test?

No. A cardiac stress test is not required for every DOT physical. It may be appropriate when the driver’s history, symptoms, examination findings, cardiac condition, procedure history, or condition-specific guidance requires additional assessment.

Must a medical examiner report an incomplete examination?

Yes. Once an examination begins, the examiner must report the result through the National Registry, including an incomplete examination, determination pending, shortened certification, or finding that the driver does not meet the standards.

Can a motor carrier tell the examiner to issue a shorter certificate?

No. A motor carrier may provide relevant job information, but it should not control the medical qualification decision or dictate a restriction or certification period. The Certified Medical Examiner must make an independent decision under the applicable standards.

Educational and Regulatory Disclaimer

This resource provides general education about federal interstate commercial-driver physical qualification examinations. It does not replace the current Federal Motor Carrier Safety Regulations, FMCSA forms, National Registry instructions, State intrastate requirements, or case-specific clinical judgment. Regulations, forms, temporary exemptions, and FMCSA guidance may change. Medical examiners should verify current requirements before making or documenting a qualification decision.
