DOT Physical Requirements and Your Health Insurance
Every commercial driver’s license (CDL) holder must pass a DOT medical examination to maintain their license. The DOT physical is conducted by a licensed medical examiner on the Federal Motor Carrier Safety Administration’s (FMCSA) National Registry. It must be renewed every two years for most drivers — or more frequently if you have specific medical conditions including blood pressure above certain thresholds, diabetes requiring insulin, vision impairment, or sleep apnea.
The DOT physical is not health insurance and is not a substitute for it. It tests whether you are medically fit to operate a commercial vehicle. It does not treat, cover, or pay for any medical condition it identifies. A driver who fails a DOT physical due to uncontrolled hypertension and loses their CDL is also facing that medical problem entirely without DOT support — only a personal health insurance plan covers the actual treatment costs.
