Some junctions controlled by traffic lights have a marked area between two stop lines. What’s this for?

Explanation: These are known as advanced stop lines. When the lights are red (or about to become red), you should stop at the first white line. However, if you've crossed that line as the lights change, you must stop at the second line even if it means you're in the area reserved for cyclists.
