Hungary has 5 motorways and 4 main roads, eight start from Budapest (exception: main road No. 8). For using the following motorways you have to buy a motorway sticker: M1, M3, M5, M6 and M7 (available at border crossing points and at petrol stations).
The Hungarian Highway Code (KRESZ) is based on the Vienna and Geneva Convention, and as such traffic signs and road markings are similar to those found in other European countries. However, it is important to highlight a few important traffic regulations that visitors to Hungary must observe at all times: use of seatbelts in the front and rear seats are compulsory; only mobile phones fitted with loudspeaker or headset microphone may be used in cars, and it is recommended that drivers making or receiving a call pull over to the side of the road in a safe area; drivers may not consume any alcohol before driving, and drunk drivers can be fined upwards of HUF 300,000 (€ 1000); the speed limit in built-up areas is 50 km/h, outside built-up areas 90 km/h, on main roads 110 km/h and on motorways 130 km/h; use of the horn in towns is only permitted in moments of danger (despite which, unfortunately, Hungarian drivers frequently use their horns without proper reason).
Caution: as of January 2008, drivers caught drinking ANY alcohol will have their driver's licences confiscated on the spot, regardless of whether the driver is a local or a foreigner.
