DOT Physical - What You Need to Know
A DOT physical is a comprehensive medical examination required by the Department of Transportation (DOT) for all commercial motor vehicle (CMV) drivers. This exam ensures that professional drivers are physically, mentally, and emotionally fit to safely operate large vehicles on public roads. The DOT physical is performed by a certified medical examiner (CME) listed on the National Registry of Certified Medical Examiners (NRCME). Passing the exam allows drivers to receive a DOT medical certificate (Medical Examiner’s Certificate, also called a DOT medical card), which is required to maintain a valid CDL license under FMCSA regulations. If you are regulated by another DOT agency and need assistance determining which DOT physical is required, call us at 800-221-4291
During your exam, the medical examiner will complete a thorough health assessment to determine if you meet the Federal Motor Carrier Safety Administration (FMCSA) medical standards. The process typically includes:
