Controlled-access highways in Romania are dual carriageways, grade separated with controlled-access, designed for high speeds. There are two types of highways, motorways and expressways, with the main difference being that motorways have emergency lanes and slightly wider lanes. The maximum allowed speed limit for motorways is 130 km/h (81 mph), while for expressways the limit is 120 km/h (75 mph). There are no toll roads, but a road vignette is required.

The A1 motorway is a partially built motorway in Romania, planned to connect Bucharest with the Banat and Crișana regions in the western part of the country and the rest of Europe. When completed it will be 581 kilometers long and it will span the country on the approximative south-east to north west direction. The motorway starts in the western part of Bucharest and connects the following major cities: Pitești, Sibiu, Deva, Timișoara, Arad, reaching Hungary's M43 motorway near Nădlac. As the motorway is built along the Trans-European Transport Networks Rhine-Danube Corridor the construction receives 85% funding from the European Union. The road is part of the proposed Via Carpatia route.
