This summer, I went to an opera event at the Salzburg Festival. Driving into Salzburg we came into a really heavy rain and hailstorm. I even feared some damage by hailstones (fortunately, my little Fiat 500 stayed unscathed). Bound in a heavy traffic, I had no chance to escape without causing a (further) chaos. No chance to just park in one of the underpasses, no gas station in sight, ... For motorcyclists it must have been much worse.
A few minutes ago, I found this at "Slate". The umbrella sign guides to designated covered areas where motorcyclists can safely wait.
We have a lot of "forbidden" road signs - to our benefit (I guess). So, I find this one pretty cool.
I can't help it, regulation and advisory comes to my mind …
