There are three types of intercity roads in Turkey: Motorways are controlled-access highways that are officially named Otoyol.

But it is not uncommon for people in Turkey to call them Otoban (referring to Autobahn) as this types of roads entered popular culture by the means of Turks in Germany.

Provincial roads (Il Yolları) are highways of secondary importance linking districts within a province to each other, the provincial center, the districts in the neighboring provinces, the state roads, railway stations, seaports, and airports.

Green: Highways that are already open to service and were developed using the BOT model, now operational and managed under this system.

The Build-Operate-Transfer (BOT) model, known as "Yap-İşlet-Devret" (YID) in Turkish, allows for private investment in highway infrastructure to support expansion and maintenance without immediate public expenditure.
