Herndon, VA DOT Physical - What You Need to Know

A DOT physical is an all-encompassing health assessment mandated by the Department of Transportation (DOT) for all commercial motor vehicle (CMV) operators. It confirms that professional drivers possess the physical, mental, and emotional fitness necessary to operate large vehicles safely on public highways. Conducted by a certified medical examiner (CME) listed on the National Registry of Certified Medical Examiners (NRCME), passing this exam grants drivers a DOT medical certificate (Medical Examiners Certificate, also known as a DOT medical card), essential for retaining a valid CDL license under FMCSA rules. If adherence to another DOT agency is required, and you need guidance on the appropriate DOT physical, contact 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:
