Prohibition Sign Icon - Universal Symbol for Restriction and Warning #3858155 (License: Personal Use)

The image displays a standard prohibition sign: a bold red circle with a diagonal red line running from upper left to lower right, set against a transparent checkerboard background. This design follows ISO 3864-1 standards for safety signage and is instantly recognizable across cultures as a warning against specific behaviors or entry. Its high-contrast red-on-transparent format ensures visibility and adaptability in digital and print media.

Commonly used on websites, apps, signage, and documentation to denote restricted actions (e.g., no smoking, no entry, disabled features). Matches user intent for visual warnings, UI feedback, or accessibility compliance.
