Prohibition Symbol | Universal "No" Sign for Safety and Compliance #66410 (License: Personal Use)

This high-contrast image displays the 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 across cultures and languages. Its simplicity and visual dominance make it ideal for warning labels, digital interfaces, and public signage where clarity and urgency are critical.

This image is commonly used in safety manuals, website UIs (e.g., disabled buttons or restricted actions), traffic signage, and regulatory documentation. It matches user intent for understanding restrictions, accessing accessibility guidance, or implementing compliant visual communication.
