OK, Still a year and a half before I get my 'over 70' licence. Had a UK license continuously since June 1971 . 47 years so far. I also hold driving licenses from Zambia and Saudi Arabia . Both those places do not recognise a UK licence for more than 6 months ,so I had to pass the driving test 3 times as I was a resident in both countries. Passed the UK test 1st time, but took two attempts at the Zambian and the Saudi test .
