How can you tell? Signs tend to be positioned so they're visible to the driver on the road to which they apply, not to drivers on crossing roads. Their placement, at least in North America, is not standardized.
In North America, in my experience, most roads have some sort of signage. So if the street I am on has no stop sign, I assume the crossing street does. I don't go out of my way looking for it.
