DN2 ({{langx|ro|Drumul Național 2}}) is a national road in Romania which links Bucharest with the historical regions of Moldavia and Bukovina in north-east Romania. Recently upgraded, it is today one of the best-maintained roads in the country. The main cities linked by the DN2 are: Bucharest, Buzău, Focșani, Bacău, Roman, and Suceava.{{cite web|title=Harta drumurilor nationale din Romania|url=http://www.e-transport.ro/Galerie_foto-HARTI_RUTIERE-245-52-2469.html|publisher=e-Transport.ro|access-date=30 August 2012|url-status=dead|archive-url=https://web.archive.org/web/20121210042731/http://www.e-transport.ro/Galerie_foto-HARTI_RUTIERE-245-52-2469.html|archive-date=10 December 2012}}

Along the first {{Nowrap|350 km}} from Bucharest to Săbăoani, near Roman the road has two lanes with one narrow emergency lane and reconstructed bridges, works which were conducted between 1993 and 2000. The road continues to Siret, at the Ukrainian border as a simple two-lanes road. Together with the adjacent section of DN28, Săbăoani – Iași, part of E583, the DN2 is currently Moldavia's backbone.{{Citation needed|date=August 2012}}

The DN2 is also considered Romania's most dangerous trunk road. The road has high accident rates, and the Bucharest–Săbăoani section is the most affected, due to drivers improperly using the emergency lanes. This has prompted the CNAIR (formerly CNADNR, the Romanian National Road Company) to upgrade a segment to a 2+1 road near the Sinești forest, the first 2+1 road in Romania. This upgrade was made in 2019, and due to the resulting low accident rates, it has been demanded that the rest of DN2 between Bucharest and Săbăoani, as well as DN28 to Iași be converted to a 2+1 road also.{{Cite web |title=Apel pentru marcarea DN2 în sistem 2+1 alternativ, după carnagiile din Bacău: "Scade viteza "bizonilor", deși viteza medie în ansamblu crește!" |url=https://zdbc.ro/apel-pentru-marcarea-dn2-in-sistem-21-alternativ-dupa-carnagiile-din-bacau-scade-viteza-bizonilor-desi-viteza-medie-in-ansamblu-creste/ |access-date=2021-08-08 |website=zdbc.ro |language=ro}}

The A7 motorway, together with the Bucharest – Ploiești section of the A3 motorway, will serve as a safer and high-speed alternative to the DN2 and will take part of traffic using the road when completed.
