Except in NL you guys actually have someone sit and think about the flow of traffic, in most other countries the design is usually pretty much random. In my parents' city in Poland they decided to turn off the traffic lights at night and the result is much higher number of accidents. Funnily, my father failed to yield the right of way exactly when talking about the issue. Yes, theoretically all intersections do have full set of signs, but in practice the visibility of those signs is extremely limited.

Most places in Poland have this exact setup. And I say most because I have not seen one that does not, but I am guessing they exist. Maybe some of them have bad visibility even?

If one does not respect the yield sign that does not seem a signaling problem.

Some don't in Finland. But then it is back to basic rule of yielding to traffic from right. Which is pretty common on smaller roads so drivers should think about it enough.

Average signaling in Poland be like

Are the words critical? As a German I read that as "you are not the priority road; you may only go left or right, but not straight"?

The words sum up to "don't go straight unless you have business being there" but still, it really sums up the approach to signaling. Nobody in the whole command chain sat and thought "that might be a tiny bit difficult to parse".

I mostly read those signs as “don't go there unless you already know you can” which as a “tourist” I just assume can't (unless I'm a local, and figure it out).

What I've recently found troubling is the places that use similar signs for emissions controls. With a rental you usually have a recent enough car that you can ignore those.

Being able to distinguish between “low emissions zone, but any car from this decade can go in” and “local traffic only, you need to live in this neighborhood to enter” in a foreign language, bit me a couple of times while traveling.
