There are warning signs to indicate people learning to drive in ex-Soviet countries (such yellow triangles to put behind the glass), even though they are driving with an instructor.
Now when I think about it, it’s been some time since I’ve seen that sign.

Somewhat similarly in the Netherlands, in case you fail your practical driving exam three times you still get a license but you can only drive cars marked with special yellow number plates.
