## Description

This callback is called when a vehicle's siren is toggled.

| Name | Description |
| --- | --- |
| playerid | The ID of the player that toggled the siren (driver). |
| vehicleid | The ID of the vehicle of which the siren was toggled for. |
| newstate | 0 if siren was turned off, 1 if siren was turned on. |

## Returns

1 - Will prevent gamemode from receiving this callback.

0 - Indicates that this callback will be passed to the gamemode.

It is always called first in filterscripts.

## Examples

```c
public OnVehicleSirenStateChange(playerid, vehicleid, newstate)
{
    if (newstate)
    {
        GameTextForPlayer(playerid, "~W~Siren ~G~on", 1000, 3);
    }
    else
    {
        GameTextForPlayer(playerid, "~W~Siren ~r~off", 1000, 3);
    }
    return 1;
}
```

## Notes

megjegyzés
