NY S03169

Amends New York City Administrative Code to require emergency signal devices on authorized emergency vehicles to produce alternating high and low, two-toned sound in accordance with department standards.

Maintains the existing maximum sound level requirement of 90 dB(A) when measured at 50 feet from the vehicle's forward face.

Requires emergency signal devices to be tested and certified every two years to verify compliance with both the sound level and two-toned alternating sound requirements.

Allows vehicle owners or operators to submit a hardship plan to the commissioner for alternative compliance timelines if meeting the standards would create undue hardship, with plans due within one year of the act's effective date.

Removes the previous exemption that had excluded police department, fire department, and medical emergency vehicles from signal device requirements.

Takes effect 180 days after enactment, with authority for the department to adopt necessary rules and regulations immediately.
