A lit cigarette in a red circle with a diagonal bar.
Also known as: No smoking sign, Smoking prohibited, Crossed out cigarette, Cigarette with a line through it
A cigarette inside a red circle with a bar across it prohibits smoking. It is probably the most widely recognised prohibition sign in the world, and the clearest example of the red-circle grammar: the circle forbids, it does not warn.
Prohibits smoking in the area where the sign is displayed.
Contexts: Public information
Demonstrates the general prohibition construction: any activity drawn inside a red circle with a diagonal bar is forbidden, so the same grammar produces no-photography, no-dogs and no-mobile-phones signs from different pictograms.
Contexts: Public information
Is increasingly drawn with a vaping device alongside or instead of the cigarette, as smoking bans have extended to electronic cigarettes in many places.
Whether a plain cigarette symbol covers vaping is a question of the local rule, not of the symbol. Symbolwise does not state what any jurisdiction prohibits.
Contexts: Public information
Belongs to the prohibition class of safety signs, drawn as a black pictogram in a red circle with a diagonal bar across it. The red circle means the depicted action is forbidden, not that it is dangerous.

A lit cigarette drawn horizontally with a wisp of smoke rising, inside a red circular outline crossed by a red diagonal bar running from upper left to lower right.
Both are circular signs whose meaning is carried entirely by colour and fill: a red ring with a bar forbids, a solid blue disc requires.
