Knobel, AR DOT Physical - What You Need to Know

A DOT physical is an in-depth health check mandated by the Department of Transportation (DOT) for all commercial drivers. This assessment ensures that drivers are physically, mentally, and emotionally capable of managing large vehicles on public roads. A certified medical examiner (CME) listed on the NRCME conducts the exam. Passing results in obtaining a DOT medical card, essential for maintaining a valid CDL license under FMCSA regulations. Call us at 800-221-4291 if another DOT agency regulates you and you need guidance on the required exam.

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:
