The department also may issue special motor vehicle license plates to former members of the General Assembly for private passenger motor vehicles and vehicles classified as private passenger motor vehicles in Section 56-3-630 owned by them. The biennial fee for these special license plates is the same as the fee provided in Section 56-3-2020, and only one plate may be issued to former members of the South Carolina Delegation of the United States Congress, retired judicial officers elected by the General Assembly or confirmed by the United States Senate, respectively, a councilman or a mayor.

A person who has been investigated by state or local authorities resulting in a resignation or convicted of a crime involving dishonesty or moral turpitude, or another crime punishable by imprisonment for at least one year may not apply for special motor vehicle license plates issued pursuant to this section. A person convicted of an offense contained in this section subsequent to issuance of a special motor vehicle license plate shall surrender the special license plate to the Department of Motor Vehicles within three days of the date of the conviction.
