Any medical practice listed on the National Registry of Certified Medical examiners can conduct physical exams for commercial driver's license applicants. The Federal Motor Carrier Safety Administration website provides a searchable version of this registry.
The law requires commercial motor vehicle drivers to hold a medical examiner's certificate stating that they are fit to drive. Commercial drivers must renew their medical certificate at least every 24 months. A medical doctor, doctor of osteopathy, doctor of chiropractic, physician assistant or advanced practice nurse can certify the driver, provided that the medical examiner is listed on the FMCSA registry. Drivers with diabetes, impaired vision or a prosthetic limb may apply for exemptions from certain aspects of the medical examination.
