My brother is not having much luck lately 
Paint skills map of accident
Right, my brother (red) was taking third exit from A41 to join M54 towards birmingham. He got onto the roundabout and got in the inside lane with indicator on. As he was going around at approx 40mph an old lady (blue) in a silver fiesta pulls out of the m54 junction onto the island and goes straight into the inside lane without no indicationg right in front of my brother, he instantly hits her rear quarter pannel and swerves off the roundabout, up the curb and stops.
She would not give him her details to start with as she was saying he was speeding, which he was not (national limit) so he rings the police who come and take statements. He had a passenger who is acting as a witness and this story matches his and she has no witness.
A woman stopped and said she was next to her and seen my brother come round, so did not pull out but seen the old woman pull out directly into his path and she was shocked she did this. unfortuantly she left the scene without giving details.
Who is at fault? Even the police officer said she really needs to take her test again
I have taken photo's and drawn out the above image to give to insurance
