A DOT physical is a health examination mandated by the FMCSA for commercial motor vehicle (CMV) drivers. A DOT physical helps determine if a driver is physically, mentally, and emotionally fit to operate a CMV.
If you are a commercial driver, you are a “safety-sensitive” employee. And for your safety and the public’s safety, FMCSA requires you to complete and pass a DOT physical to maintain a valid commercial driver’s license (CDL).
WHAT TO EXPECT DURING A DOT PHYSICAL
During a DOT physical, a CME will check your vital signs, review your medical history, and perform a required hands-on physical examination that includes (but is not limited to):
- General appearance
- Eyes
- Ears
- Mouth and throat
- Heart
- Lungs and chest
- Extremities
- Nervous system
- Hernias
- Back and spine
The CME will issue you a medical examiner’s certificate (MEC) – also called a DOT medical card – when you meet the DOT physical requirements. Without a valid DOT medical card, you can lose your CDL.
As of 2023, CMV drivers with insulin treated diabetes mellitus (type 1 or type 2) and/or monocular vision must meet updated standards to be certified. Forms for these exemptions must be completed at least 45 days before the DOT exam is performed.
