The helmet laws for motorcycle riders will change in North Carolina on January 1. The purpose of the new law is to clarify what types of helmets riders can wear. The law also makes clear that riders must use a strap to secure the helmet.
There is a Federal Motor Vehicle Safety Standard (FMVSS) 218 that motorcycle helmets must meet to be within the law. That standard requires helmets to have a firm inner liner of polystyrene foam that is about one-inch thick.
Riders can look for the "DOT" symbol on helmets, which the state says all compliant motorcycle helmets carry.
