General description: Lower numbers tend to be more important routes.
Highway 1 is the main west-east route on Sumatra, Java and Bali from Banda Aceh to Merak and then via Jakarta, Semarang and Surabaya to Ketapang, and the southern main east-west route on Bali.
Odd numbers generally run east-west and even numbers north-south. Despite their name, national roads are numbered per island. For example, highway 2 is Jakarta - Bogor on Java but also Singaraja - Mengwi on Bali. More or less by coincidence, highway 1 can be seen as one road with ferries between the islands.

Road signs: Green with white text.
Since the national and provincial numbering was introduced recently, the numbers are not indicated yet on most signs. When they are, they appear as a white hexagon with black digits.
Since around 2015, Asian highways are signposted in a white rectangle.
|
| History: The system was probably introduced around 2007. |
