What does the yellow diamond grid on the road indicate?

[MacNora]

It informs drivers that temporary parking is prohibited at intersections (or other entrances/exits) where this marking is installed, serving as a road marking to prevent traffic congestion. Below is more information about traffic markings: 1. White dashed line: When painted on road sections, it separates traffic flows in the same direction or serves as a safe driving distance indicator; when painted at intersections, it guides vehicle movement. 2. White solid line: When painted on road sections, it separates motor vehicles and non-motor vehicles traveling in the same direction or indicates the edge of the lane; when painted at intersections, it can serve as a guide lane line or stop line. 3. Yellow dashed line: When painted on road sections, it separates opposing traffic flows; when painted on the roadside or curbs, it prohibits long-term parking on the roadside.
