The rule
Connecticut 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; the violation cannot be considered as contributing to the cause of an accident in any civil action. Failure to wear a helmet is not, by itself, grounds for a fine on a first offense if a conforming helmet is purchased. See Conn. Gen.

Statute
What this means in practice
If you're 16 or older, Connecticut 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 ANSI Z90.4 or Snell B-90 (a CPSC-certified helmet satisfies both). 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.
