No Smoking Sign - Universal Prohibition Symbol for Smoke-Free Zones #3253085 (License: Personal Use)

The image displays the internationally standardized no smoking sign: a bold red circular border enclosing a white field, with a black cigarette emitting smoke, overlaid by a thick red diagonal slash from upper left to lower right. This design follows ISO 7010 and traffic signage conventions for prohibitory symbols, ensuring high visibility, immediate recognition, and cross-linguistic comprehension. Its stark color contrast (red, white, black) enhances legibility even at a distance or in low light.

This sign is commonly posted in airports, hospitals, schools, restaurants, public transit, and government buildings to comply with health regulations and inform the public of smoking restrictions; it matches user intent seeking clarity on where smoking is banned or verifying signage standards.
