Validity of International Driving License

Welcome to the forums.

An international driving permit is only a translation of your existing license. Despite what some sources may claim, it can not be used without a valid driving license from your home country and only for a certain time periods as a tourist (i.e. if you become a resident of Hungary your third party license my be considered invalid immediately or only after some months --- you will need to ask the appropriate local Hungarian government office for details what and how this may affect you).

If your home country has an exchange policy with Hungary or EU, then you can simply exchange your current license for a Hungarian one. If not, you will need to take and pass a written driving test and a behind the wheel test to get a valid Hungarian license.

Kuwait, India and Hungary are signatories to the 1968 Vienna Convention on Road Traffic which means mutual recognition of the IDP.   So you should be able to drive on your Kuwait license and IDP for a short time.  However, as said before you'll need a Hungarian license if you live here.  There are not many direct exchange countries - like Korea, possibly Japan and all of the EU.   

The IDP system is a muddle of mutual recognition so you need specific advice.    You should contact the automobile club in your country.  They usually know everything about these things as they are usually dealing with IDPs/Carnets etc and should know the rules. 

There is a Hungarian auto club but their web site is only in Hungarian.
