What is the purpose of the road grid lines?

[SanTucker]

Yellow grid lines on the road indicate a strict prohibition against all vehicles stopping for any length of time, whether temporarily or long-term, to prevent traffic congestion. Here are the relevant details: 1. Function: When there is a vehicle stopped ahead of the yellow grid lines, the following vehicle must wait outside the yellow grid lines until it is confirmed that there is sufficient space ahead for the vehicle to stop before proceeding over the grid lines. 2. Application: Yellow grid lines are also painted in front of important national institutions, military bases, large enterprises, school entrances, and public transportation hubs to ensure that vehicles can enter and exit without being blocked by congestion at the entrance. The grid lines are yellow, and stopping within them is prohibited.
