Highway Code Rule 178

Advanced stop lines. Some signal-controlled junctions have advanced stop lines to allow cyclists to be positioned ahead of other traffic. Motorists, including motorcyclists, MUST stop at the first white line reached if the lights are amber or red and should avoid blocking the way or encroaching on the marked area at other times, e.g. if the junction ahead is blocked. If your vehicle has proceeded over the first white line at the time that the signal goes red, you should stop as soon as possible and MUST stop at the second white line. Allow cyclists, including any moving or waiting alongside you, enough time and space to move off when the green signal shows.

Drivers of large vehicles should stop sufficiently far behind the first white line so that they can see the whole area where cyclists may be waiting, allowing for any blind spot in front of the vehicle.
