What equipment must a moped have to be operated on public roadways?

The correct choice states that a moped must have operable pedals, a rearview mirror, headlights, brake lights, and regular seating to be operated on public roadways. This comprehensive set of equipment ensures that the moped is safe for operation and meets legal requirements.

Operable pedals are essential because they signify that the vehicle can be manually powered, which is a defining characteristic of mopeds. A rearview mirror is necessary for safe navigation, allowing riders to be aware of their surroundings and other vehicles approaching from behind. The presence of functioning headlights is critical for visibility during low-light conditions, while brake lights are equally important for signaling stopping intentions to other road users, enhancing safety.

Moreover, regular seating is part of the definition of a moped, ensuring that riders have a designated space to sit while operating the vehicle. This equipment collectively contributes to the rider's safety as well as the safety of others on the roadway, thereby meeting the legal requirements for operating mopeds in South Carolina.
