Prohibition Sign Icon - Universal No Symbol for Web and Print Use #3031338 (License: Personal Use)

This image displays the standard international prohibition symbol-a thick red circle crossed by a diagonal red line from upper left to lower right-set against a clean white background. The design follows ISO 3864-1 standards for safety signage, ensuring immediate recognition across cultures and languages. Its simplicity and high contrast make it effective in digital interfaces, printed warnings, and regulatory contexts.

Used on websites, apps, safety manuals, and public signage to denote restricted actions (e.g., no smoking, no entry, prohibited items). Matches user intent for finding clear, accessible icons for UI/UX design, legal compliance, or educational materials.
