Prohibition Symbol | Universal No Entry Sign for Safety and Compliance #3425924 (License: Personal Use)

This image displays the internationally standardized prohibition symbol-a thick red circle intersected by a red diagonal slash from upper left to lower right, set against a solid black background for maximum contrast and visibility. The design follows ISO 7010 and ANSI Z535 standards for hazard communication, ensuring instant recognition across cultures and languages. It's commonly used in traffic control, workplace safety, digital interfaces, and public signage to convey bans on smoking, entry, parking, photography, or other restricted behaviors.

Used in safety manuals, warning labels, web UIs (e.g., disabled buttons or blocked actions), transportation signage, and regulatory documentation. Matches user intent for understanding restrictions, designing compliant interfaces, or sourcing universal symbols for accessibility and legal adherence.
