South Carolina's current helmet law:

SECTION 56-5-3660

Helmets shall be worn by operators and passengers under age twenty-one; helmet design; list of approved helmets.

It shall be unlawful for any person under the age of twenty-one to operate or ride upon a two-wheeled motorized vehicle unless he wears a protective helmet of a type approved by the department. Such a helmet must be equipped with either a neck or chin strap and be reflectorized on both sides thereof. The department is hereby authorized to adopt and amend regulations covering the types of helmets and the specifications therefor and to establish and maintain a list of approved helmets which meet the specifications as established hereunder.

ABATE of South Carolina amended the above helmet law in 1980 to allow adult freedom of choice!
