No Smoking Sign - Universal Prohibition Symbol for Tobacco Use #3860251 (License: Personal Use)

The image displays the internationally standardized no smoking symbol: a black cigarette with rising smoke, enclosed in a red circle crossed by a bold red diagonal line. This design follows ISO 7010 standards for safety signage and ensures immediate visual recognition across languages and cultures. Its high-contrast color scheme (red, black, white) maximizes visibility and compliance in diverse environments.

Commonly used on walls, doors, digital interfaces, and printed materials in airports, hospitals, schools, workplaces, and public transport to indicate smoke-free areas; matches user intent for identifying prohibited zones or designing regulatory signage.
