Bill > SB1094

This bill addresses noise pollution caused by emergency vehicle sirens by requiring all new motor vehicles legally permitted to have sirens (such as ambulances and emergency response vehicles) to be equipped with dual frequency sirens starting January 1, 2026. A dual frequency siren is defined as a pneumatic two-tone siren with two sets of air horns (one high-pitched and one low-pitched) or similar technology. The legislature finds that while traditional "wail" sirens and dual frequency sirens reach similar decibel levels, dual frequency sirens produce a less piercing noise that travels more effectively through an immediate area and reduces noise pollution. The bill aims to mitigate the negative mental health effects of loud sirens, particularly in urban areas, by mandating this siren technology for all new emergency vehicles purchased or contracted in the state of Hawaii. The new requirement will be added to Chapter 321 of the Hawaii Revised Statutes and will take effect upon approval.
