Removing points from a license?

[tom26]

I got 3 points for failing to comply with traffic signals just over 3 years ago now. I was wondering whether I have to wait 3,4 or 5 years to get these points removed from my license and how do I go about doing it?

So now that I've past 3 years does that mean if I were to get 3 more then I'd still only have 3 but they'd last for another 4 years?
