Merit, 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 commercial motor vehicle (CMV) operators. This examination verifies that drivers are physically, mentally, and emotionally equipped to handle large vehicles on public roadways safely. A certified medical examiner (CME), listed in the National Registry of Certified Medical Examiners (NRCME), conducts the DOT physical. Success in the exam grants drivers a DOT medical certificate, or Medical Examiners Certificate, often referred to as a DOT medical card, necessary to uphold a valid CDL license per FMCSA guidelines. If you're subject to another DOT agency's regulation and require help identifying the required 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:
