Do Not Sign - Universal Prohibition Symbol for Safety and Compliance #3363496 (License: Personal Use)

This image displays a universally recognized prohibition symbol: a red circle with a diagonal slash over the capitalized words “DO NOT” in bold black font on a white background. The design follows ISO 3864 standards for safety signage, ensuring high visibility, immediate recognition, and cross-linguistic comprehension. It is commonly deployed in environments where unauthorized actions pose risks to people, property, or compliance.

Used on websites, safety manuals, warning labels, and public signage to indicate forbidden actions (e.g., no entry, no smoking, no photography). Matches user intent for understanding visual warnings, creating compliant content, or designing UI/UX alerts.
