The rule
North Carolina requires a bicycle helmet for any rider under the age of 16. The same rule extends to children carried as passengers in a child seat or trailer. Civil infraction; no court costs assessed. Parents and guardians can be held responsible. The Department of Transportation maintains a helmet-distribution program for low-income families. See N.C. Gen. Stat. § 20-171.9.
If you're 16 or older, North Carolina doesn't require you to wear a helmet by state law. Riders under 16 (and any child carried as a passenger) must wear a helmet that meets the CPSC, ASTM, ANSI, or Snell standard.
Cities can be stricter than the state floor, and bike-share systems often require helmets regardless of age. If you're renting or commuting in a major city, confirm the local rule before you ride.
