Federal Motor Carrier Safety Regulations require all Commercial Driver License holders to certify with the State’s Driver License Agency in one of the four categories below prior to the issuance or renewal of a CDL. Those certifying in non-excepted interstate or intrastate commerce (Category A or C) must also ensure their medical documentation is on file with the state issuing agency and that it remains current. Failure to present valid medical documentation, when required, will result in the denial of the issuance or renewal of the CDL. Failure to maintain current medical documentation on file may result in CDL disqualification.
CDL holders can no longer claim exemption from medical certification requirements because they are not currently operating in non-excepted interstate or intrastate commerce. If not specifically included in category B or D above, they must maintain their medical certification or downgrade to a non-commercial license.
Note: If you self-certify in a category exempt from medical certification requirements (Category B or D) and later change to a non-exempt type of operation (Category A or C), you must recertify in the appropriate category and provide proof of valid medical certification to avoid potential enforcement actions.
