Driving in Poland after Schengen Status

I am an Indian and has an Indian government issued Driving License; I think, for now, I cannot drive in Poland and need an IDP; But once Poland joins Schengen by Dec 21 or so, will the driving rules become similar to Schengen states? I have driven in France, Germany, Belgium, Netherlands, Luxembourg and Italy with my Indian Driving license;

Am not sure Poland will have the same driving restrictions even after becoming Schengen;

Anyone has any idea of this? Or will

you should get an international driving licence. i believe you only just got away with the indian one while driving in europe.
anyway it doesn't cost much and definitely has you on the safe side...

There is no separate test conducted to issue an IDP; It is nothing but a translation to international format and in English so it can be used abroad; In Schengen States, I still had my insurance working, if purchased; So, it is perfectly safe to drive with indian license in such european countires; I know even in Quebec State and in Toronto, I am allowed to drive for 6 months with no need for IDP;

I was interested to know whather I need an IDP in January when Poland is a Schengen state; You know, there is some bureacracy and time taken to get IDP in India; That is my problem;
