What Is a DOT Physical?
A DOT physical is a medical examination mandated by the Federal Motor copyright Safety Administration (FMCSA). It ensures that drivers are physically, mentally, and emotionally fit to operate CMVs. The exam is conducted by a certified DOT medical examiner, who is trained and listed on the National Registry of Certified Medical Examiners (NRCME).
DOT Physical Requirements Overview
Before undergoing the exam, it's essential to know the DOT physical requirements. These requirements help determine whether a driver is qualified to receive a medical certificate, which is valid for up to 24 months (or less if medical conditions require closer monitoring).
Key Health Checks in a DOT Physical
A certified DOT medical examiner will assess several areas of health during the physical:
Vision
- Minimum of 20/40 vision in each eye (with or without corrective lenses)
- At least 70 degrees peripheral vision in the horizontal meridian
Hearing
- Must perceive a "forced whisper" at 5 feet or better, with or without hearing aids
Blood Pressure & Pulse
- Ideal blood pressure: Less than 140/90
- Pulse rate is checked for irregularities or underlying conditions
Urinalysis
- Tests for glucose, protein, and signs of underlying medical conditions such as diabetes or kidney disorders
Physical Exam
- Examination of the lungs, heart, spine, extremities, and neurological functions
Conditions That May Require Additional Review
Some conditions don’t automatically disqualify a driver but may require further documentation or more frequent monitoring:
- Diabetes controlled with insulin (requires FMCSA exemption or certification)
- Sleep apnea (CPAP compliance documentation may be necessary)
- Vision or hearing aids
- Cardiovascular disease (recent tests or clearance may be needed)
What to Bring to Your DOT Exam
Being prepared can ensure a smooth exam. Bring the following:
- A valid driver’s license
- List of current medications
- Glasses or hearing aids if used
- Medical records for chronic conditions
- Previous medical certificates (if renewing)
Role of a Certified DOT Medical Examiner
A certified DOT medical examiner must complete specialized training and pass a certification exam. They are responsible for:
- Performing the physical per FMCSA guidelines
- Ensuring accurate reporting and documentation
- Issuing a Medical Examiner’s Certificate (MEC) if the driver meets all DOT physical requirements
Their role is vital in ensuring that only medically fit individuals operate large or potentially hazardous vehicles on public roads.
Conclusion
Understanding DOT physical requirements is critical for commercial drivers.

Whether it's your first time or you're renewing, staying informed helps you meet the health criteria necessary to keep driving safely and legally.
