no smoking
no smoking, 금연 신호
This is an international symbol indicating that smoking is not allowed. It features a cigarette with a diagonal line across it inside a red circle.
It is commonly seen in places where many people gather, such as schools, hospitals, and restaurants. It's a very important sign for health and a clean environment.


As a symbolic sign of the no-smoking movement that has spread globally since the 1970s, it has become even more important as the dangers of secondhand smoke have become known. In modern society, no smoking in public places has become basic etiquette.
Since 2015, Korea has implemented a complete ban on smoking in all restaurants and is one of the countries with the strictest no-smoking policies in the world, including restrictions on street smoking. These policies are greatly contributing to protecting citizens' health rights and creating a pleasant environment.
