I don't really know what you're doing but try this:

pawn Код:

CMD:m(playerid, text[]) return cmd_megaphone(playerid, text);
CMD:megaphone(playerid, text[])
{
    if(PlayerMuteInfo[playerid][AllMuted]) return SendClientMessage(playerid, TEAM_CYAN_COLOR, "   You can't speak, you have been silenced!");

    if(IsACop(playerid) || IsAnAmbulance(GetPlayerVehicleID(playerid)))
    {
        if(IsAnAmbulance(GetVehicleModel(GetPlayerVehicleID(playerid))) || IsACopCar(GetVehicleModel(GetPlayerVehicleID(playerid))))
        {
        // Action here
        }
        else SendClientMessage(playerid, COLOR_LIGHTRED, "   You are not in a police vehicle!");
    }
    return 1;
}
