What does the elephant icon on the highway mean?

[LeAnastasia]

Highway elephant signs indicate frequent elephant crossings. Here are some details about highway icons: 1. Introduction: Highways are the highest-grade roads, with speed and road conditions completely different from urban roads, and are fully enclosed. In signage, they generally use "G" as the prefix, similar to national highways, such as G3. Provincial highways use "S" as the prefix. Both national and provincial highways have white lettering on a green background, with national highways featuring a red horizontal bar above and provincial highways a yellow decorative strip. 2. Types: There are various types of traffic signs, which can be categorized in multiple ways: main signs and auxiliary signs; movable signs and fixed signs; illuminated signs, luminous signs, and reflective signs; as well as variable message signs that reflect changes in driving conditions.
