Thornton, TX DOT Physical - What You Need to Know
A DOT physical is an extensive health assessment mandated by the Department of Transportation (DOT) for all operators of commercial motor vehicles (CMVs). This evaluation ensures drivers possess the necessary physical, mental, and emotional stability to safely handle large vehicles on the roads. Conducted by a certified medical examiner (CME) registered with the National Registry of Certified Medical Examiners (NRCME), clearing this exam grants drivers a DOT medical certificate (also known as a DOT medical card), essential for retaining a valid CDL license as per FMCSA guidelines. For guidance on the required DOT physical if you fall under another DOT agency's jurisdiction, 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:
