An internship certificate is sometimes also called "appendix 4" or "certificate of training".
It is used by candidates whose provisional driving licence is no longer valid, and who cannot find a supervisor to apply for a new provisional driving licence (M12).
The internship certificate can be obtained from the town hall, in exchange for the expired provisional driving licence.
On condition that 6 hours of driving lessons are followed after the expiry of the provisional driving licence, the candidate can take a driving test with this internship certificate (no need to wait another 5 months). Driving lessons are of course also possible.
