I read that i need the toll road sticker and i need some help.
1) Can i buy the sticker inside Austria? Is there any kind of tolerance before you must bear the sticker on the windshield?
2) how easy is to buy that sticker on hungary petrol stations?
3) Is the price fixed or any petrol stations charges you whatever they want?
4) Any recoomended place to lunch during the whole budapest -> Vienna route?
Thanks a lot :)
