DOT Physical Exam Requirements for CDL Drivers
Every driver operating a commercial motor vehicle (CMV) in interstate commerce must pass a DOT physical examination and carry a valid medical examiner's certificate. The exam must be conducted by a medical examiner listed on the FMCSA National Registry of Certified Medical Examiners (NRCME) — a physician, chiropractor, PA, NP, or DO who has completed FMCSA's certification program. This guide covers the full scope of DOT physical requirements under 49 CFR Part 391 Subpart E.
Who Needs a DOT Physical Exam?
A DOT physical is required for any driver who operates a CMV in interstate commerce, where a CMV is defined as a vehicle that:
- Has a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) over 10,001 lbs
- Is designed or used to transport 9–15 passengers (including the driver) for compensation
- Is designed to transport 16 or more passengers regardless of compensation
- Transports hazardous materials in quantities requiring placards under 49 CFR Part 172 Subpart F
CDL holders must complete a separate self-certification process with their state DMV in addition to obtaining the medical certificate from an NRCME examiner.
Where to Get a DOT Physical
DOT physicals must be conducted exclusively by medical examiners listed on the FMCSA National Registry of Certified Medical Examiners (NRCME), searchable at nationalregistry.fmcsa.dot.gov. Physicals conducted by unlisted examiners — even licensed physicians with decades of experience — are not compliant and must be redone. Eligible examiner types include: MDs, DOs, PAs, nurse practitioners, and chiropractors who have completed FMCSA training and passed the certification exam.
What the DOT Physical Exam Covers
The physical examination uses Form MCSA-5875 (Report of Medical Examination) and covers:
- Vision: Distant visual acuity of at least 20/40 in each eye with or without correction; field of vision at least 70° in the horizontal meridian in each eye; ability to recognize red, green, and amber traffic signal colors
- Hearing: Perceive a forced whispered voice in the better ear at not less than 5 feet with or without the use of a hearing aid, or if tested by audiometry, not more than a 40 dB hearing loss in the better ear
- Blood pressure and cardiovascular health: BP readings; history of cardiovascular disease, arrhythmias, MI, pacemaker use
- Neurological: Epilepsy history, seizure disorders, loss of consciousness, head injuries
- Respiratory: Spirometry if respiratory condition suspected; sleep apnea assessment
- Musculoskeletal: Range of motion, limb loss, prosthetics
- Urinalysis: Sugar and protein screening (not a DOT drug test — separate process)
- Mental health: History of mental disorders, current medications
Certificate Validity Periods
The medical examiner issues the certificate (Form MCSA-5876) with an expiration date of up to 24 months. However, the examiner may issue a shorter certification period if the driver has:
- Hypertension requiring medication (Stage 1 hypertension: annual certification)
- Insulin-treated diabetes mellitus (ITDM) under a federal exemption (annual or shorter)
- Sleep apnea being treated with CPAP (typically annual)
- A pending specialist evaluation
- Any other condition the examiner determines warrants closer monitoring
Disqualifying Medical Conditions
The following conditions result in automatic disqualification absent a federal waiver or exemption:
| Condition | Disqualifying Standard |
|---|---|
| Vision | Worse than 20/40 in either eye corrected, or inability to recognize traffic signal colors |
| Hearing | Cannot perceive whispered voice at 5 ft in better ear (without aids) or >40 dB loss |
| Epilepsy | Any epilepsy currently requiring medication or with activity in past 8 years |
| Substance use | Use of any Schedule I substance, amphetamines, narcotics, or habit-forming drugs |
| Alcoholism | Current clinical diagnosis of alcoholism |
| Cardiovascular | Current cardiovascular disease likely to interfere with driving (e.g., recent MI, unstable angina, complete heart block) |
| Insulin-treated diabetes | ITDM without an active FMCSA federal exemption |
| Limb loss | Loss of a limb without an FMCSA Skills Performance Evaluation (SPE) certificate |
Federal Exemption and Waiver Programs
FMCSA operates several federal exemption and waiver programs that allow drivers who would otherwise be disqualified to continue operating under specific conditions:
- Insulin-Treated Diabetes Mellitus (ITDM) Exemption: Drivers using insulin can apply to FMCSA for a federal exemption program. Approved drivers receive annual certification with monitoring requirements.
- Vision Waiver: Drivers who fail the standard vision requirements may apply for a vision exception if they have at least 20/40 in one eye and no vision in the other, and have substantial driving experience.
- Skills Performance Evaluation (SPE) Certificate: Drivers missing a limb or with limited use of a limb may obtain an SPE certificate that allows driving with adaptive equipment after a road test administered by an FMCSA motor carrier safety specialist.
DOT Physical vs. DOT Drug Test
These are separate procedures that are often confused. The DOT physical (medical exam) determines whether the driver meets FMCSA's medical standards — vision, hearing, cardiovascular health, etc. The DOT drug test (urine specimen collection, lab testing, and MRO review) is a separate process required before a driver's first safety-sensitive trip and on a random and triggered basis thereafter. The urinalysis component of the DOT physical tests for glucose and protein — not drugs. A driver can pass the physical and fail the drug test, or vice versa.
Motor Carrier Responsibilities
Motor carriers are responsible for:
- Verifying that every CDL driver's medical certificate is current before each trip
- Retaining a copy of the medical examiner's certificate in each driver's DQF
- Tracking expiration dates and ensuring drivers renew before certificates lapse
- Checking that the examiner is on the NRCME before accepting a certificate
- Documenting the annual medical certificate review as part of the DQF annual review process

Track Medical Certificate Expiration for Every Driver
CarrierLens tracks each driver's DOT medical examiner's certificate expiration date in their DQF and sends alerts before the certificate lapses — so no driver reaches their expiration date unnoticed. When a renewed certificate is issued, it's uploaded directly to the driver's file and the expiration clock resets automatically.
See Medical Certificate Tracking →Never Let a Driver's Medical Certificate Expire Unnoticed
CarrierLens tracks every driver's DOT medical certificate expiration date and fires alerts at 60, 30, and 7 days before expiration. When the renewed certificate is uploaded, the expiration clock resets automatically in the DQF — no manual tracking required.
