What is the difference between blue and green road signs?
2 Answers
Blue signs are used for general roads, while green signs are used for highways or expressways. Here are the specific details about road signs: 1. Function: The number of cars in cities increases by hundreds every day, and road resources are becoming increasingly scarce. Reasonable layout of traffic signs, increased traffic monitoring, one-way streets, and time-limited traffic restrictions all require signs to alert people. The connection and transition between various traffic facilities absolutely cannot do without road signs. 2. Significance: Analyzing the environment, understanding regional culture, local customs, architectural style, road conditions, citizen quality, regional status, number of tourists, and many other factors are comprehensively considered to determine the overall planning of the urban signage system, followed by regional subdivision.
After driving on the road for so many years, I've observed road signs thoroughly. Blue road signs usually indicate ordinary urban roads, pointing to street names, schools, or shopping malls. Their mild color is suitable for slow-speed driving in the city. Green road signs, however, are entirely different—they are specifically designed for highways, commonly seen at entrances, exits, and service areas. Their bright and eye-catching color facilitates long-distance recognition, improving driving efficiency. I remember once on a long-distance trip, a friend couldn't recognize the green signs and delayed our journey. Fortunately, I taught him how to distinguish them in time. Blue represents local roads for daily use, while green symbolizes expressways. Understanding this can avoid many detours. Beginners might easily confuse them, but once you develop the habit, driving becomes safer. For daily commutes, observing and remembering more is key—road sign designs are very considerate.
