A backup alarm works by emitting a loud, audible signal when a vehicle is put into reverse. It is usually activated automatically when the reverse gear is engaged. The alarm's primary function is to alert pedestrians and nearby workers of the vehicle's movement to prevent accidents. Most backup alarms produce a beeping sound, although some modern versions use broadband sound for better localization and reduced noise pollution in surrounding areas.
