As a reminder: https://en.wikipedia.org/wiki/Priority_signs Of course I'm just asking about what you see from the minor road, the priority road user would always see the white and yellow square or equivalent.
Here the general rule is to use Stop signs only when visibility is bad and there's more yield signs which don't require you to fully break. I'd say the proportion is about 65/35 but it's hard to estimate. But I get the impression looking at some countries in google street view that it's hard to find any yield signs there.
