My point here, though, is that common sense
doesn't resolve the conflict.

Near my office is a road that crosses a couple of railroad tracks. South of
the road's crossing of the tracks, there's a fence between the two tracks.
Where that fence ends, next to the road, is a sign:

Do not cross railroad tracks

Unfortunately, that sign gives every appearance of requiring that one not
follow the road (or the pedestrian way along the road) across the tracks.
Although I've not checked, I'm reasonably sure that it is supposed to mean
"cross tracks only at designated crossings".

It irks me when people that author signs - or rules - cannot do so clearly
and accurately. For what else are they being paid?
