Starting September 1, 2026, the legal speed limit on residential roads has been changed to 30 km/h.
"Is this road 30 km/h?" is a free service provided by the National Police Agency that classifies approximately 8.53 million roads nationwide into categories of "30 km/h candidate / requires confirmation / likely not applicable" and allows you to check them on a map.
When you click on a road, you can also see "why this classification" for that road.
※This does not determine the actual maximum speed. On-site traffic signs and road markings take priority.
