The general prohibition sign,[1] also known informally as the no symbol, 'do not' sign, circle-backslash symbol, nay, interdictory circle, prohibited symbol, don't do it symbol, or universal no, is a red circle with a 45-degree diagonal line inside the circle from upper-left to lower-right. It is typically overlaid on a pictogram to warn that an activity is not permitted, or has accompanying text to describe what is prohibited. It is a mechanism in graphical form to assert 'drawn norms', i.e. to qualify behaviour without the use of words.[2]
