..Police were good, they said it appear quite obvious the driver create the collision rather than I being in the wrong by hitting it from behind, they're also aware that I am in the right despite driver's protest that I was in the wrong and shouldn't have been on the road (i.e. not the blue stuff).
Be careful of this one Ed. Because you were not seriously injured the police will not put any resources into sorting this out. Do you have any witnesses? If you make a claim the driver could come back with a different story putting all the blame on you. I would get a solicitor to chase the police for details of statements and reports. Make sure you have written down everything you remember and detail all the minor bruises and scratches.
