Indonesian National Route 12 is a relatively short, yet heavily used road in the national route system.

It serves as one of the major arteries in the Jabodetabek region (also known as Greater Jakarta), as the road spans through areas considered as part of the metropolitan area itself.

Despite its location, it spans through three provinces, that is Jakarta, Banten, and West Java, as the road itself connects Senayan, South Jakarta, Jakarta on the northern end, with Bogor, Bogor Regency, West Java in its southern end.

Because of its heavy use and presence in Greater Jakarta, this route is notorious for having heavy traffic, particularly during the rush hour.
