Prohibition Sign Icon - Universal Symbol for Forbidden Actions #317055 (License: Personal Use)

This iconic prohibition symbol consists of a thick red circle crossed by a diagonal red line from upper left to lower right, set against a white background. It is standardized under ISO 7010 as the "Prohibited" sign (P001) and conveys immediate visual warning without language dependence. Its high-contrast design ensures visibility and rapid comprehension in safety, traffic, and regulatory contexts.

Commonly used on signage in public spaces, workplaces, transportation, and digital interfaces to indicate banned activities (e.g., no smoking, no entry, no parking). Matches user intent for understanding safety symbols, designing UI/UX alerts, or creating compliance documentation.
