Sometimes Road Signs Speak the Truth – 1 (humor)

Sometimes, permanent traffic signs almost seem to be designed to be ignored (and therefore lose much of their safety value at relevant times).  One classic example of this, in the lower 48 states of the USA, might be the very common signs stating ‘Road Subject to Ice,’ but in a late July heatwave it’s a pretty safe bet they don’t mean ‘right now!’

The permanently positioned sign on the right reads ‘Water Over Roadway’ and it would seem to be telling the truth at this particular moment in time!  Clearly this is a relatively common event at this location.  (Copyright image, 2017.)

Puzzling or Inaccurate Road Signs: No.1

Unclear or inaccurate traffic signs, road signs, pavement markings or road markings — call them what you prefer — can cause confusion or even danger.

Here’s one from Colorado, photographed in May 2018, but what exactly does it mean?

Photograph of a road sign that reads: "In case of flood climb to safety."
Confusing traffic signs: What exactly does this mean? Climb onto the roof of your car? Somehow try to get to a tree and assuming you are young, strong and nimble, climb that? Swim for the nearest hillside? The ONLY safe message in relation to road vehicles is do not drive into water that is covering the road and is either flowing or may be deeper than it looks.
