Driving New Jersey

It is illegal to attach a siren or whistle to your bicycle.

Status: Still Enforced / On the Books

The Law Explained

While bells and basic horns are actively encouraged for safety, state traffic laws specifically forbid outfitting a standard bicycle with an emergency-style siren or a steam-style whistle. This ensures that pedestrians and motorists do not mistake an overly enthusiastic ten-year-old on a bicycle for an approaching fire engine or police vehicle.
