No Smoking Sign - Universal Prohibition Symbol for Smoke-Free Zones #3335081 (License: Personal Use)

The image displays a standardized no smoking sign: a bold red circular border enclosing a white background, with a black cigarette emitting smoke at the center, overlaid by a thick red diagonal slash from upper left to lower right. This design follows ISO 7010 and traffic sign conventions, ensuring high visibility, immediate recognition, and cross-cultural comprehension. The stark color contrast (red, white, black) enhances legibility even at a distance or under poor lighting.

Commonly used in public spaces such as airports, hospitals, schools, restaurants, workplaces, and transportation hubs to comply with health regulations and indicate legally enforced smoke-free zones; matches user intent for safety signage, policy compliance, or public health communication.
