Prohibition Sign Icon - Universal Symbol for Forbidden Actions #189764 (License: Personal Use)

This high-contrast image displays the standard prohibition symbol: a thick red circle intersected by a diagonal red line from upper left to lower right, set against a black background. The design follows ISO 3864-1 standards for safety signage, ensuring immediate recognition across cultures and languages. It conveys restriction, ban, or inadmissibility without text, relying purely on visual semantics.

Used on websites, apps, signage, and documentation to indicate disabled features, restricted access, prohibited actions (e.g., no smoking, no entry), or error states. Matches user intent seeking clarity on restrictions or visual cues for policy enforcement.
