What is the yellow dotted line inside the circle?

[LeAnthony]

The yellow dotted line inside the circle is an intersection guide line. Below are the specific details about intersection guide lines: 1. Form: The intersection guide line connecting the same-direction lane dividing line or the motorized/non-motorized dividing line is a white curved (or straight) dotted line; the intersection guide line connecting the opposite-direction lane dividing line is a yellow curved (or straight) dotted line. 2. Function: Intersection guide lines are designed to allow left-turning vehicles to proceed in an orderly manner within this lane, improving intersection traffic efficiency. For example, when the left-turn signal and the straight-through signal turn green, turning vehicles and straight-going vehicles may experience some congestion. During heavy traffic, turning vehicles might encounter "cutting in" situations. Therefore, multiple guide lines need to be set up at intersections. All vehicles must drive orderly on the inner side of the guide lines when passing through these points for left turns.
