When it first goes to STOP (i.e. amber) a driver is required to stop unless it is unsafe to do so. There could be occasions when a driver could not safely stop at the first line but could do so within the few extra yards of the cyclists' line. In doing so they would end up in the ASL area. In terms of safety, that would be preferable to their continuing past the signal at STOP.
The signal goes to amber about 3 seconds before red.
This means that a driver is a long way from the stop lines at the point they need to decide whether to continue or to stop. At 30mph this is about 40m nearly twice the stopping distance in the HC, which means that there is a considerable margin where a driver could choose to stop comforatably before the first stop line or to proceed through the junction well before the lights change to red. If theyare so close that they cannot stop safely before the first line they should continue.
There is no legitimate reason for a driver to obstruct the cyclists space, unless they are waiting to turn right.
