The one about cows is no joke. Hitting a cow in a sedan at highway speeds is more or less the same as hitting a brick wall.

Edit: actually, given the choice, take the brick wall, because at least a simple masonry wall will crush and crumble and absorb some of the impact. The cow will just gain a sudden increase in its net velocity at your expense.

I take it you don't have any particular idea where any of these are actually found in the wild..?

I dunno, but if that 5 roundabouts thing is real, I damn sure don't wanna go anywhere near there!

The Speed Camera Ahead is everywhere where live. Why is it strange?

The one with "No speed limits" doesn't mean that you can go 200 in a 90, it just means that previous speed signs no longer apply. So if you had a speed sign of 70 in a road that typically allows to go 90, you can do 90 again.

Reading through this I feel like about a quarter of the signs are regulars here in switzerland.

There used to be one in this town that just said "open water" with no elaboration.

It means they built a damn and flooded where the road used to go and it now goes directly into a lake.

The “Illegal Immigrant Crossing” signs are real down in San Diego, CA. Poor girl is always getting dragged like that.

What’s wrong with no water pollutants? It’s around drinking water reservoirs so they don’t get contaminated in a case of an accident…
