1994 for 6 months on a totting up procedure.
First 3 points for the rear L plate having fallen off the pizza delivery bike i was on at the time. Unmarked astra and when i stopped and they stopped behind me i thought they were gonna mug me for the cash and the pizza!

rather they had tbh
It was all really stupid carp as i'd driven without a licencse for about 3 yrs before that. The final 3 points were either a nonsense or karma catching up with me but either way they got me.
Happily i was due to relocate and work in the cannaries the following month so it made very little diffrence as i cold drive on my old provisional license that i still had laying about.
Joke of it all was that i tld the hire cars guys over there that the points are given for good driving in london and they were very impressed.
Not big and not clever...but its history...and you asked.
