What is the yellow cross sign?

[LucyDella]

Represents a cross intersection, used to warn vehicle drivers to proceed with caution, slow down, and pay attention to oncoming traffic from the sides. It is a sign placed at an appropriate location on the approach to a poorly visible level intersection. Below are specific details about level intersections: 1. Meaning: A level intersection is a multi-way intersection where roads intersect at the same level. The point where roads intersect on the same plane is called a level intersection. Roads connect with each other through intersections to form a road system, facilitating connections in all directions. 2. Purpose: The internal area design of an intersection primarily aims to resolve conflicts between different traffic flows, providing clear passage space for various types of traffic, reducing traffic conflicts, and enhancing safety. The main design elements include the channelization of internal space, such as non-motorized vehicle passage space design, pedestrian crossing design, traffic island design, guide lines, waiting area design, and stop line design.
