What does the white 80 road marking mean?

[MacIsabela]

Ground markings with the number 80 in white indicate a minimum speed limit of 80 km/h. Ground markings with the number 80 in yellow indicate a maximum speed limit of 80 km/h. White numbers on the ground represent minimum speed limits, while yellow numbers represent maximum speed limits. Below are specific details about minimum speed limit signs: 1. Meaning: Road traffic signs are facilities that use graphic symbols, colors, and text to convey specific information for traffic management. They play a role in ensuring smooth traffic flow and driving safety, so drivers and all road users must comply with them. Traffic safety slogans can enhance drivers' and road users' awareness of voluntarily following traffic regulations, which is significant for building a safe and smooth traffic environment. 2. Current situation: In China, speed limit signs are primarily set up by dividing road sections. For general road sections with good alignment, speed limits are determined based on operating speeds. Other sections are set up according to traffic conditions or based on road traffic accident situations.
