Red Circle Symbol - Universal Prohibition and Warning Icon #3703578 (License: Personal Use)

This image displays a solid red circular outline with uniform thickness, set against a transparent background indicated by a gray-and-white checkerboard pattern. The design follows international standards for prohibition signs, where a red circle (often with a diagonal slash) conveys restriction or danger. Its vector-style simplicity ensures scalability and clarity across web, print, and signage applications.

This image is typically used in web design, safety signage, user interfaces (e.g., disabled buttons or error states), and instructional materials to denote prohibition, cancellation, or alert. It matches user intent for visual cues indicating “not allowed,” “error,” or “stop.”
