Travel anywhere in the Sydney metro (this was taken at Coogee beach) and you’re likely to see these little stop signs below the signals. The three stacked black circles are meant to convey “if the signal is out, stop here.” Many of the signs also have another text sign beneath them explaining the concept.
The approach puzzles me. Isn’t it common sense to do just that? Is another sign needed? Makes me wonder what inspired all these signs to go up. An accident? A lawsuit? (If so, you’d think we’d have ’em in America.) Or are they just really, really unreliable signals?
Seems like something better suited to a rule you learn in driver education.
