How can i help with this please?
That is not really realistic I'm afraid. This is going to lead to a prosecution.
They may charge you with failing to stop and report and also with careless driving. If you plead to careless driving they may drop the failing to stop and report. That is a common deal that they accept.
if so, that would mean the conviction that you have is non recordable and so not on DBS.
I'm afraid that they are not likely to accept an alternative to prosecution though.
Can I clarify anything for you?
