What it does
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
Current law generally prohibits any vehicle from being equipped with a flashing or rotating light. Authorized emergency vehicles, such as police vehicles, fire department vehicles, ambulances, conservation warden vehicles, designated emergency vehicles of municipal or county departments, and designated emergency vehicles of state departments are exempted from this prohibition. Most emergency vehicles may be equipped with red lights or red and white lights, but police vehicles may be equipped with red and blue lights. Under this bill, a police vehicle may, in addition to other authorized lights, be equipped with one or more flashing white lights.
