Vermont 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. 23 V.S.A. § 1139 requires every person under 16 to wear an approved bicycle helmet whenever operating or riding as a passenger on a bicycle on any public highway, including in a child trailer. The first offense is dismissed if a helmet is acquired; subsequent offenses carry a fine of up to $15. See 23 V.S.A. § 1139 (Bicycle helmets required for persons under 16).
If you're 16 or older, Vermont 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.
