Prohibition Sign Icon - Universal No Entry Symbol #1951237 (License: Personal Use)

The image displays a standard prohibition sign: a thick red circle with a diagonal red slash crossing from upper left to lower right over a black circular field. This design follows ISO 3864-1 standards for mandatory safety signage and is used globally to denote actions, objects, or areas that are strictly prohibited. Its high visual contrast ensures immediate recognition even at a distance or under poor lighting.

Used on warning labels, traffic signs, workplace safety posters, digital interfaces (e.g., disabled buttons), and regulatory documentation to signal restrictions. Matches user intent for understanding compliance, hazard avoidance, or UI feedback.
