Prohibition Symbol Icon - Universal No Entry Sign #3010006 (License: Personal Use)

This iconic symbol consists of a thick red circle intersected by a red diagonal line from upper left to lower right, set against a solid black background for maximum contrast and visibility. It is standardized under ISO 7010 and widely recognized across cultures to denote prohibition, restriction, or disallowance of an action or item. Its design ensures immediate comprehension in signage, user interfaces, and regulatory contexts.

Used in traffic signs, safety warnings, digital UIs (e.g., disabled buttons), and regulatory documentation to communicate restrictions clearly and universally. Matches user intent for finding authoritative, accessible prohibition icons for web, print, or compliance use.
