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

HF 728 updates Iowa's vehicle code to standardize equipment requirements for emergency vehicles like police cars, fire trucks, and ambulances. It requires new lighting features (such as rear zone amber lights and master warning switches) and dual-tone sirens for vehicles purchased or refurbished after specific dates (July 1, 2021, or 2022). The bill applies directly to state and local governments, fire departments, EMS providers, and vehicle manufacturers. It removes redundant language like "official" before vehicle types but does not change driving privileges or emergency operation rules.
