No Smoking Sign - Universal Prohibition Symbol for Smoke-Free Zones #2217464 (License: Personal Use)

The image displays a classic prohibition sign: a bold red circle with a diagonal red slash overlaid on a black cigarette emitting smoke. Designed for high visibility and instant recognition, it adheres to international safety signage standards (e.g., ISO 7010). The stark contrast of red, black, and white ensures legibility from a distance and across diverse lighting conditions.

This image is commonly used on signage in airports, hospitals, restaurants, workplaces, and public transportation to indicate smoke-free zones; it aligns with user intent to locate or confirm non-smoking areas and supports compliance with health regulations.
