The distance is approximately 240-250 km. Both Hungary and Austria require a motorway vignette (electronic toll sticker) for driving on their respective highway networks. A 10-day Hungarian vignette for cars typically costs around HUF 6,620 (approx EUR 17-18), and a 10-day Austrian vignette for cars is approximately EUR 12-13. These can be purchased online or at border crossings and petrol stations. Fuel costs are estimates and depend on vehicle efficiency and current fuel prices (e.g., EUR 1.50-1.60 per liter for gasoline). Ensure your vehicle has the required equipment for each country (e.g., reflective vest, first-aid kit).
