When did this happen?
Ok. They are in time then.
Are you asking if you have a defence?
If you reported within 24 hours then they are unlikely to charge you with failing to stop and report.
More likely they are looking at driving without due care and attention.
That carries 3-9 points or a potential ban although the reality is that, unless the cyclist was badly injured, it would only be 3 points.
There would also be a financial penalty but I know that isn't your main concern.
Can I clarify anything for you?
Sorry but surely you don't have the cyclists contact details?
I can make an offer.
The reason you are experiencing delay is that you keep posting before I have responded.
In that case I won't be able to offer more.
All the best.
