The rule
New Jersey requires a bicycle helmet for any rider under the age of 17. The same rule extends to children carried as passengers in a child seat or trailer. Civil penalty of up to $25; the same statute also covers roller skates, skateboards, and scooters. Parents are responsible for ensuring compliance. See N.J. Stat. § 39:4-10.1.
Statute
What this means in practice
If you're 17 or older, New Jersey doesn't require you to wear a helmet by state law. Riders under 17 (and any child carried as a passenger) must wear a helmet that meets the ANSI or Snell (a CPSC-certified helmet meets these older specifications) 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.
Get the fit right
Find your CPSC-certified helmet size
A helmet that meets the law but does not fit will not protect you. Measure your head circumference, then shop a size band you can trust.
