Prohibition Symbol - Universal No Entry or Forbidden Sign #2010307 (License: Personal Use)

The image displays a standard prohibition symbol: a thick red diagonal line crossing a black square, enclosed by a red border. Its high-contrast color scheme ensures visibility and immediate comprehension across cultures and contexts. Widely adopted in traffic control, workplace safety, and digital UX, it conveys “not allowed” without text.

Used in safety signage, web UI (e.g., disabled buttons), regulatory documentation, and public warnings; matches user intent to understand restrictions, compliance requirements, or interface feedback.
