Commercial drivers operating in certain types of commerce are required to obtain a "certified" medical status and maintain the status to avoid losing their commercial driver license.
There are four commerce types, two of which require a certified medical status.
Drivers required to maintain a certified medical status must provide a U.S. Department of Transportation medical examiners certificate to the N.C. Division of Motor Vehicles by visiting a driver license office, emailing it to CDLmedical@ncdot.gov or mailing it to:
N.C. Division of Motor Vehicles
CDL Medical Certification Unit
3126 Mail Service Center
Raleigh, NC 27697-3126
For DOT medical examiner's certificates that are only valid with a vision, diabetes or a skills performance evaluation variance, the Federal Motor Carrier Safety Association will provide a copy of that variance to NCDMV.
Determining Commerce Type
Detailed information for determining whether a driver is required to have a certified medical status can be found in Section 1.3 of the Commercial Driver Manual.
