Which statement about the installation of crosswalks is correct?
Crosswalks are installed by the Commissioner of the Metropolitan/Provincial Police Agency, and the minimum distance from other crosswalks, overpasses or underpasses differs by road type: 100 or 200 meters (Article 11 of the Enforcement Rule). There are exceptions for protection zones and the like, and unpaved roads have their own installation method.
Answer: ③
Explanation
Crosswalks are installed by the provincial police commissioner (Road Traffic Act Article 10(1)). Under Article 11 of the Enforcement Rules, they are in principle not placed within 100 meters on collector and local roads, or within 200 meters on other roads, of a footbridge, underpass or another crosswalk. Exceptions apply in school zones, silver zones or disabled protection zones or where pedestrian safety especially requires it. On unpaved roads, a crosswalk sign with a supplementary sign showing its width is installed instead of markings.
