Prohibition Symbol - Universal No Entry or Forbidden Sign #223198 (License: Personal Use)

This high-contrast red circle with a diagonal slash is the international symbol for prohibition, commonly used in traffic signs, safety warnings, and user interfaces to denote forbidden actions. Its design follows ISO 7010 standards for clarity and immediate recognition across cultures and languages. The stark red-on-white color scheme ensures visibility and urgency.

Used on websites, apps, and physical signage to communicate restrictions (e.g., no smoking, no entry, disabled features). Matches user intent for understanding rules, compliance, or interface feedback.
