SB1094

Hawaii SB1094 mandates dual frequency sirens on new motor vehicles to reduce noise pollution.

Hawaii SB1094 addresses noise pollution by requiring all new motor vehicles equipped with sirens to use dual frequency sirens. These sirens, which consist of two sets of tones, aim to reduce noise pollution and negative mental health effects, particularly in urban areas. The lower pitch of these sirens is less piercing and travels more effectively through the immediate area, while the higher pitch ensures audibility at longer distances. This change takes effect starting January 1, 2026.
