Hello everyone. I would like to ask. Do you need to buy an entry card when entering Austria? Do you also need to buy a highway card if you go by highway ?

Thank you.

The convenience store in the gas station on the expressway sells it. You need to buy a expressway ticket when you cross to Austria. The toll fee is collected by the car rental company.

There is no such thing as a mirror card. Only expressway tolls are required. After entering Austria, purchase at the convenience store of the first gas station and you're all set.
