This section provides the Registry of Motor Vehicles' current medical policies relating to Commercial Driver's Licenses (Classes A, B, and C) only. Detailed information can be found at the US Department of Transportation's Federal Motor Carrier Safety Administration (FMCSA) Website.
A customer must meet minimum, federally-mandated medical standards to be eligible to obtain or hold a commercial driver's license. A customer is physically qualified to drive a commercial motor vehicle if he/she either:
1. Has an interstate medical exemption or a Massachusetts medical waiver
2. Meets the physical qualification standards outlined in Federal Regulation § 391.41, found on the Federal Motor Carrier Safety Administration (FMCSA) Website.
To ensure that a commercial driver meets these medical standards, he/she must pass a Department of Transportation medical examination performed in accordance with 49 CFR §391.41 and 49 CFR §391.43. Department of Transportation medical examinations are conducted by a licensed medical examiner.
A Department of Transportation medical examiner's certificate is generated by this examination. Medical examiner's certificates are valid for a maximum of two years.
In order to operate a Commercial Motor Vehicle with a gross vehicle rating in excess of 10,000 pounds in interstate commerce, a medical examiner's certificate may also be required, even if the customer does not have a Commercial Driver's License.
