Prohibition Symbol | Universal "No" Sign for Safety and Restrictions #190322 (License: Personal Use)

This high-contrast image features a standard prohibition symbol-a thick red circle crossed by a diagonal red line-set against a solid black background. The design follows ISO 3864-1 standards for safety signs, ensuring immediate recognition and unambiguous meaning. Its vector-style clarity makes it suitable for both print signage and digital UI elements where visual authority is critical.

Used in safety manuals, traffic signage, website UI (e.g., disabled actions), and regulatory documentation to indicate banned activities, restricted access, or hazardous conditions. Matches user intent for understanding warnings, compliance visuals, or icon libraries.
