If I understand your question correctly, then yes - I had to surrender my Irish licence in exchange for a UK licence.
That's good to know. Given that a person only has one UK licence, what impact does this have on the fact that I recently qualified (in March 2015 through Direct Access Scheme) to drive a motorcycle?
Sorry - I'm not fully understanding this. Why would I need to take the bike test again?
I'm on a 20 year old licence - and it's the licence that gets the points, not the vehicle / vehicle category.
