It's an immediate fail if you actually drive through
an unmarked crossroads at speed - even if you
are on the more major road (despite the fact that
generally speaking - most traffic on the more major
road will simply drive through without slowing)

But how can you know the junction is unmarked until you are already passing
through it?

If you can't see any markings, assume it is unmarked.
If you want to check the markings before passing
through the junction, travel at an appropriate speed.
