Prohibition Symbol - Universal "No" or "Forbidden" Sign #3642576 (License: Personal Use)

This 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 neutral background. The design follows ISO 3864-1 standards for safety signage, ensuring high visibility and immediate recognition across cultures and languages. It conveys absolute restriction without text, relying on color contrast and geometric simplicity.

Commonly used in traffic signs, workplace safety posters, digital interfaces (e.g., disabled buttons), and public notices to indicate banned activities (e.g., no smoking, no entry, no photography). Matches user intent for visual communication of restrictions, compliance guidance, or UI/UX design assets.
