What does a road elephant mean?

Elephants are often seen in Xishuangbanna. When I saw this sign when I was driving, I was reminding that there might be elephants crossing the road here. Other traffic signs on the expressway are also important. If you don't pay attention, it may bring inconvenience to your trip: 1. Toll station information sign: Generally, the sign on the right will have a toll station prompt. At this time, you should slow down and keep the distance between cars, and choose the channel according to the tips of the toll booth. 2. Distance reference signs: Small signs such as 0M, 50M and 100M are often seen on expressways. This is a ranging sign, which can clearly see the distance from the car in front and avoid traffic accidents due to too close distance. 3. Harbor parking zone: Harbor parking zone extends to the outside of the road, where vehicles can stop for a short rest. 4. Lane warning signs: There will be lane warning signs (fonts printed on the road surface) at intervals above the expressway lane or on the road surface. Include maximum and minimum channel names. 5. Service area sign: This is a common indicator sign on the expressway, and it is also a place to rest and refuel when driving at high speed.
