Yes
Police cars have sirens.
To warn other cars it is coming through!
Policies and laws vary from state to state, but in my locality, police officers basically use sirens (and lights) any time they are responding to an emergency call. If they are responding to a silent alarm, they may choose to not use sirens, but that's not common around here.
the sirens tell people that a car is coming also it sends a signal to stoplights for a go.
Chicago is famous for having only Blue lights on its police cars

They have upgraded engines. They have additional lighting.. beacon lights, wig-wag flashers for the head and tail lights, radios, sirens, a shield between the driver compartment and rear passenger area, a rack for the shotgun, etc.
The french police drive terrible cars with terrible sirens were as the Miami police department drive good cars with good sirens, also they have a better way of processing people and information in the Miami police department. Also, the Miami police probably need better training, because Miami is the most crime-filled state in the US.
Lights, and Siren.
Looking at pictures of these Police cars it does not look like they had sirensAdded: I believe that they used alarm bells or "military horns" (alternating high-low pitch)

In the 1920s, police cars began to evolve from traditional horse-drawn carriages to motorized vehicles, reflecting the rapid advancements in automotive technology. These early police cars were often modified versions of standard automobiles, equipped with sirens, lights, and sometimes even radio communication. The introduction of these vehicles allowed for quicker response times to incidents and increased the visibility of law enforcement in urban areas. As a result, police cars became an essential tool in modern policing, enhancing public safety and law enforcement capabilities.
