Mike R is correcto mongo
Most bans its 4 years from Date of offence , So if you can hang the court date out long enough
Like mine did 19 months your only stuck with it on your licence for 2 ish years
...
Also few thoughts for you
Data Protection act you dont have to disclose your points to anyone incl insurers
However they do have a clause that says if they were to find out that your a lying fudge packer they will invalidate your insurance
They only check when there is a claim processed to protect themselves ( i thiknk thats fair )
They will normally ask for your licence to be sent it to them at claim point to confirm your points etc
SO
if you know your likely to be banned get points etc
Think about writing to the DVLA with £20 or what it is and ask them for a replacement licence for the one you have lost ...

This will arrive with your CURRENT endorsements etc
Then when you go to court give them the licence to endorse etc knowing that you have one in your pocket thats clean/er this also helps when you are trying to hire a car
I currently have 2 licences (Both now cleaner than a virgins knickers)
The 3 year rule has stated is for the courts to take into consideration . IE if yoru court for the same type of offence later they will assume that you havent learnt from the last time and hit you harder
After 3 years they will not be told of your "previous"
