Prohibition Sign Icon - Universal No Entry Symbol #172864 (License: Personal Use)

The image displays a standard prohibition symbol: a thick red circle with a diagonal red slash crossing through a black circular field, set against a transparent or white background. Its high visual contrast ensures immediate recognition across cultures and contexts, making it ideal for warning signs, regulatory notices, and user interface elements where action must be blocked or restricted. The design adheres to ISO 7010 and ANSI Z535 standards for universal comprehension.

Commonly used on road signs, workplace safety posters, software interfaces (e.g., disabled buttons), and regulatory documentation to indicate forbidden actions. Matches user intent for searching “no entry sign,” “prohibited symbol,” or “universal stop icon” for design, legal compliance, or educational purposes.
