Prohibition Symbol - Universal No Entry or Forbidden Sign #3098332 (License: Personal Use)

The image displays a high-contrast prohibition symbol: a thick red diagonal line crossing a black square with rounded corners. This minimalist design is widely recognized across cultures as indicating restriction, ban, or inaccessibility, commonly used in traffic signs, software UIs, and safety warnings. Its visual clarity ensures immediate comprehension even at small sizes or from a distance.

Used in web design (e.g., disabled buttons, error states), transportation signage (no entry, no parking), and safety documentation to convey restrictions. Matches user intent for understanding or implementing universal “forbidden” indicators.
