Requires helmet while operating bicycle, scooter, or motorized scooter.

Bill A4887 requires people under 17 to wear helmets while operating bicycles, scooters, or motorized scooters in New Jersey, expanding current helmet requirements that previously applied only to bicycles. The bill mandates businesses selling or renting these devices to post warning signs and provide helmets to minors who don't have them, with civil immunity for compliant businesses. It exempts certain areas like trails or closed roads from the helmet requirement but applies when operating on public roads or paths. This bill amends existing laws to cover additional personal mobility devices with the goal of increasing safety.
