My first 6 points was an offence dated x my second 6 points offence was x is that calculated as 12 points as first offence is just over 3 years old.
If the first offence was x then these penalty points remain effective until x. Therefore the offence on the x does not add up with the previous 6 points and you are not at risk of a totting ban.
Hope that makes you feel better. Be careful going forward and keep my details. What went wrong with the no insurance. Do you accept it was your fault?
