How to install:
Download file into your plugins folder
Does this work on LSPDFR?
How do I use it:
When in an emergency vehicle, press N and the siren gets muted. You can change the keybind in GTA's settings under the FiveM Keybind section.
You can use this in any of your servers without crediting me, but don't claim it as your own and resell it or give it to anyone. If you want to share it, just give them this GTAPoliceMods link.
