What are you hoping to achieve?
Why didn't you respond?
Ok. There is no doubt that you were speeding I suppose? You were the driver?
Thank you and I’m sorry for the delay.
There is not really much point in writing to them. They're going to prosecute you because if they do not they cannot be sure of any conviction for anything at all.
One option is to attend court and off the plea to speeding in exchange for them dropping the failing to notify. They do quite regularly except that kind of bargain.0 if that happens then you will just be prosecuted to the speeding alone which will carry three points and a fine.
If they do dig their heels in and refuse then your only option is to plead guilty to failing to notify. That carries six points and a much higher fine. You can mitigate on the same day that you plead guilty. It is only mitigation as there is case law that says that a person abroad or away should keep tabs on his post but nevertheless it is mitigation. It doesn't make a huge difference to your sentence really anyway as it only carries points and a fine.
Can I clarify anything for you?
Not really. Then you would be pleading guilty to failing to notify without the opportunity to offer a plea to speeding.
