Weird traffic light

The driver knew perhaps its time to test that very junction where the traffic light there was always red. He had driven there for quite a few times and it seemed to be forever red. Then he would return disappointed each time he went there. Of cos, this oso meant he would not reach his destination in time as a detour would be needed. Finally he decided to try his luck yet again and he is lucky to see a green light. And finally off he drove to his destination.
