Having just returned from an 18,000km trip to the northern end of that big hunk of dirt that stops the NT & SA from blowing away (oops) I can now reflect on aspects of the trip. One such item of interest is the use & placement of roadside advisory signs.
We came across a number of speed advisory signs that didn't make sense, to us at least. A slight bend on bitumen that had a speed advisory sign of 70km..now this corner was so slight it could have been traversed at 90/100km in the wet with complete safety but a little further along a bend that tightened up considerably & in the wet would have been a handful at 60km had no sign. I guess the local/state engineers have guides to refer to but the consistency often seems hard to fathom.
Flood depth indicators are a real case in point. Some are placed in the middle or near by of the bridges/culverts/floodways, others at the entrance to the bridge/culvert/floodway & others are marked "deepest point" which is the one I prefer. We took a photo of one floodway with it's marker on the entrance & by line of sight to the base of the marker on the other side estimated the deepest point to be at least 500mm below the base of the markers at the entrance. This could have a profound effect on the safe crossing of this floodway by a motorist.
Is this type of advisory signage supposed to be uniform across all borders & if not maybe it should.

Every day vertical above ground is a bonus.
