Here ya go NJ:
Here's a copy of the first letter I received, after I requested a copy of the photo:
//// Dear XXXX
Thank you for your recent communication in connection with the above notice.
As requested, I am enclosing photograph(s) which may assist you in identifying the driver of the vehicle at the time of the alleged offence, together with a further S172/request for information form. Please be advised that under section 172 of the Road Traffic Act 1988 you have a legal duty to provide information which may lead to the identification of the driver.
If you are unable to provide this information, then the matter may be dealt with by the Magistrates' Court.
Yours faithfully XXXX ///////
After I wrote back explaining that the image was blurred, etc, this was their reply:
////Dear XXXX
Thank you for your recent communication in connection with the above notice.
To date, you have not provided information which may lead to the identification of the driver of the above vehicle, as you are required to do under S172 of the Road Traffic Act 1988. The Act states that you must exercise reasonable diligence in providing this information.
In this instance, I understand that the photograph(s) does not assist you in identifying the driver and instead of issuing a summons for you to appear before the Magistrates' Court, you are to treat this letter as a warning, on the understanding that this defence will not be accepted for any future offences.
Yours faithfully XXXX ////
RESULT :)
