A bill for an act relating to police, fire department, and other emergency vehicles.

HF 938 updates Iowa's emergency vehicle equipment standards. It requires police, fire, EMS, and emergency management vehicles purchased or refurbished after specific dates (2021-2022) to have: rear zone amber lights or arrows (not on front/sides), a master switch to activate all emergency lights, and sirens with at least two distinct tones. The bill also removes redundant "official" wording before vehicle lists in the law. These changes directly affect state and local emergency vehicle operators by standardizing safety equipment requirements. The bill does not alter when emergency vehicles may exceed speed limits or run red lights.
