Concerns certain interactions between law enforcement officers and juveniles.

This bill requires all individuals under 17 years old to wear a certified bicycle helmet while riding a bicycle (including in child seats or trailers), and mandates helmets for those under 18 operating motorized bicycles. It specifies exemptions for certain bike trails, roads closed to motor vehicles, or paths with physical barriers, and clarifies that municipalities may adopt local ordinances for these exemptions. The law explicitly allows law enforcement officers to issue warnings or fines for helmet violations (including fines for parents/guardians) without conflicting with existing protections against enforcing underage alcohol/cannabis laws. It directly affects minors, parents, and law enforcement officers in New Jersey.
