• Alert People: The loud noise tells people on the road that the police are coming. This way, they can move aside and let the police pass.
• Scare Off Bad Guys: Sometimes, when the bad guys hear the siren, they might get scared and stop running.
• Help Find the Bad Guy: The siren helps the police get to the bad guy faster so they can help keep everyone safe.

When you hear a police siren, you should listen for it and move to the side of the road if you are walking or riding your bike. That way, you are safe and letting the police do their job!
