As in real-life, the highway is only half-finished and exists in two sections. They are linked up by about 90 km (56 mi) of minor road in the middle. To simulate the view better, there are various towns en-route rendered in-game but unlabelled or even not accessible to truckers. Examples include Považská Bystrica and Ružomberok.
- While Slovakia has its own signs for numbered roads in real-life, the Diaľnica D1 in the game uses Czech-styled number signs.
- The easternmost section of the road, near Košice, is also part of the Rýchlostná cesta R4 in real-life.
