Prohibition Symbol - Universal "No" or "Forbidden" Sign #3377998 (License: Personal Use)

This high-contrast image features a standard prohibition symbol: a thick red circle intersected by a red diagonal slash from upper left to lower right, set against a solid black background. The design follows ISO 3864-1 standards for safety signs, ensuring immediate recognition and compliance in regulatory, industrial, and digital interfaces. Its simplicity and visual clarity make it effective for conveying restrictions without text.

Commonly used in traffic signage, workplace safety notices, digital UIs (e.g., disabled actions), and regulatory documentation to indicate forbidden behavior or prohibited items. Matches user intent for understanding warnings, designing accessible interfaces, or sourcing universal symbols.
