Serbia

Motorways (Serbian: Аутопут, romanized: Autoput) and expressways (Serbian: Брзи пут, romanized: Brzi put) are the backbone of the road system in Serbia. There are around 906 km (563 mi) of motorways in total. Plan is 1,200 km (750 mi) by the end of 2018.

Motorways in Serbia have three lanes (including emergency lane) in each direction, signs are white-on-green, as in the rest of former Yugoslavia and the normal speed limit is 130 km/h (81 mph).

Expressways, unlike motorways, do not have emergency lanes, signs are white-on-blue and the normal speed limit is 100 km/h (62 mph).

As the Serbian word for motorway is autoput, the "A1", "A2" or "A3" road designations are used since November 2013. All state roads categorized as class I, that are motorways currently of in the future, are marked with one-digit numbers and known as class Ia. All other roads, which belong to class I, are marked with two-digit numbers and known as class Ib. Expressways belong to class Ib, too. E-numeration is also widely used on motorways.

The core of the motorways is what was once called during Yugoslav period, the Brotherhood and Unity Highway, which was opened in 1950 and goes from the border with Croatia, through Belgrade, Central Serbia, Niš, and to border with North Macedonia. It was one of the first modern highways in Central-Eastern Europe. It is the most direct link between Central and Western Europe with Greece and Turkey, and subsequently the Middle-East.
