I understand, but your comment was: "That's right, in California, 4-way stops aren't labelled 4-way" which is true in practice but not any more useful than saying "4 way stops aren't labelled 4-way anywhere" because some intersections may not be up to code. They are SUPPOSED to be labelled. You can probably get them fixed by reporting it to the local government.
