Speed is not only about the limit on the sign. It is a continuous decision based on traffic, weather, visibility, road surface and your own condition. Government guidance emphasises obeying limits and adjusting for conditions. Choosing a safe speed means asking: Can I stop within what I can see? Is this appropriate for rain, glare or pedestrians? Am I alert enough for this speed? This mindset shifts speed from “what can I get away with?” to “what is safe right now?”. That shift alone reduces risk significantly.
