I've done a pic because I cant explain this very well;
I was in the left hand lane at this junction (me) waiting to go straight on at the lights (1), it was a dual carriageway so I had car A and car B to my right. Just past the junction there is a crossing, as pictured. While we were waiting for the lights to change the light at the crossing changed to red. Now, car A and car B moved forward to wait at the crossing even though our lights were still red.
I held back though as surely that counts as skipping a red light?? There were cars turning right onto the dual c/w from the side-road so we didn't have right of way right?
