United Kingdom
After learners in Great Britain pass their driving test, they may opt to display green P-plates (for "probationary") to show their lack of experience; this is entirely voluntary however. Some new drivers use green L plates (the pre-test colour being red), however as the L usually stands for Learner it is more common to use P Plates.
My dad once got pulled over on the motorway because his car had red L plates on! My mum had been practicing, but they swapped just before we got on the M-way, but forgot about the plates.
