My friend @donkeypong here are you how are you? asking you interesting questions, I am interested in knowing how things were created and the meaning of each things, there is always an answer for something for example the traffic signs each shape and color has a meaning right now I do not remember just read once about that

I am glad to know that it is your country to comply with the rules here in my country it does not matter much a traffic signal or a traffic light people are usually imprudent and there is nobody watching at home signal or traffic light to fine these people
