Rhode Island 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. RIGL § 31-19-2.1 requires every person under 16 to wear an approved protective helmet whenever operating or riding as a passenger on a bicycle. The first violation is dismissed if a helmet is purchased; subsequent offenses carry fines up to $50. The statute also applies to children riding in attached child seats and trailers. See RIGL § 31-19-2.1 (Helmets required for operators and passengers under 16).
If you're 16 or older, Rhode Island 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 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.
