Columbus, TX DOT Physical - What You Need to Know

A DOT physical is a thorough medical checkup mandated by the Department of Transportation (DOT) for all commercial motor vehicle (CMV) drivers. This examination verifies that professional drivers are physically, mentally, and emotionally capable of safely operating large vehicles on public roads. 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 to maintain a valid CDL license under FMCSA guidelines. For assistance in determining which DOT physical applies to you, especially if regulated by a different DOT agency, 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:
