Northwest Marin, CA DOT Physical - What You Need to Know

A DOT physical is an all-encompassing health assessment mandated by the Department of Transportation for every commercial motor vehicle (CMV) operator. This examination establishes that drivers are physically, mentally, and emotionally capable of maneuvering large vehicles safely on public highways. A certified medical examiner, listed on the National Registry of Certified Medical Examiners, conducts the exam. Success in this exam awards the driver a DOT medical certificate, necessary to keep a valid CDL license as per FMCSA guidelines. If another DOT agency regulates you and you're unsure which DOT physical you require, 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:
