Prohibited 🚫
Copy & Meaning

A prohibited sign — the most versatile and commonly used prohibition symbol, a red circle with a diagonal slash that communicates 'not allowed' across virtually all cultural contexts. This symbol appears modified with specific icons beneath (no bikes, no smoking) but also stands alone as a general prohibition. It's one of international signage's most effective designs — legible without language, immediately understood.

Online, it represents refusals, blocks, and the definitive 'no' to requests. Used for prohibition and restriction of any kind, strong refusal expressions, content warnings, social media blocks and restrictions, safety signage references, and any communication where a clear, emphatic, visually immediate 'this is not permitted' is the message.
