Prohibition Sign Icon - Universal No Entry Symbol for Safety and Compliance #2007747 (License: Personal Use)

This image displays the standard international prohibition symbol: a thick red circle crossed by a diagonal red line from upper left to lower right, set against a black background for maximum contrast and visibility. Designed for instant recognition, it conveys “not allowed” without language barriers, commonly applied in traffic control, workplace safety, and digital interfaces. Its simplicity ensures effectiveness even at small sizes or under poor lighting conditions.

Used on safety signage, website warning modals, app permission dialogs, transportation signage, and regulatory documentation; matches user intent seeking visual cues for restrictions, warnings, or policy enforcement.
