I’m ready to help, but I don’t have enough context yet. It seems you may be asking about waiting restrictions or related traffic signs, perhaps in a specific country (e.g., the UK or Germany). To give an accurate answer, could you clarify:

• Which country or region are you asking about?
• Are you looking for a general explanation of waiting restrictions, or the meaning of a specific sign?
• Do you need guidance on what “waiting,” “no waiting,” or “no stopping” signs permit (e.g., maximum waiting times, whether loading/unloading is allowed, etc.)?

If you can share a bit more detail, the explanation can be tailored precisely.
