Inspired by a post by DaleF about cars crossing the frozen lake near where she lives, I looked up a photo I had noticed in Google Earth. It is the one below, showing a river crossing with no fewer than 8 traffic signs, all of which make perfect sense. The most obvious one is the blue one in Cyrillic letters saying that this is the river Pechora. Then there is the roman-lettered international STOP sign.
I wonder if my fellow bloggers will work out what the other signs mean...
Of the remaining six signs one seems to be redundant and another one only applies outside the winter season.
Have fun puzzling!
