Who must wear a helmet in South Carolina, the penalties for not wearing one, and the eye-protection rules every rider should know.
South Carolina has a partial motorcycle helmet law. Operators and passengers under 21 must wear an approved protective helmet at all times while riding; the helmet must have either a neck or chin strap and be reflectorized on both sides (p.1-12).
Riders 21 and older may legally ride without a helmet. The manual still strongly recommends one for every rider, since head injuries account for a majority of serious and fatal motorcycle injuries (p.3-1).
Motorcycle operators and passengers under 21 must wear an approved helmet at all times while riding.
Operators under 21 must also wear goggles or a face shield. Riders 21 and older are exempt from both requirements, but a securely fastened DOT helmet and good eye protection remain the best things you can do to survive a crash (p.1-12, 1-13).
Riding without a required helmet or eye protection when under 21 — or carrying an under-21 passenger without an approved helmet — violates South Carolina law. Moped operators under 21 must likewise wear a helmet and goggles or a face shield. Confirm current penalty amounts with the SCDMV or local law enforcement.
Separate from the helmet rule, South Carolina requires motorcycle operators under 21 to wear goggles or a face shield (p.1-13).
A windshield is not a substitute — it will not protect your eyes from wind and debris. A full-face helmet provides the most face and eye protection, and tinted eye protection should never be worn at night (p.3-4).
A legal motorcycle helmet must meet the U.S. Department of Transportation (DOT) FMVSS 218 standard. Look for the "DOT" certification label on the back. Helmets that meet stricter Snell or ECE standards offer additional protection. Avoid novelty helmets — they are not legal head protection.
