What are the highway road signs?

[ReedLynn]

License plate guidance information, road signs, functional purpose signs, and lane detail signs. Here is the detailed introduction of relevant information: Sign information: Service areas are common traffic signs on highways and are also essential stops for rest. They are usually indicated by the capital letter P. Typically, there is a service area every 30 kilometers. Lane information includes speed limit traffic signs that appear at regular intervals on highways, with the maximum speed limit generally set at 120 KM/H. Precautions: Correct and concise signs can provide clear instructions without obstructing the driver's view, enabling more efficient travel on highways. Adhering to speed limit signs ensures safer journeys.
