a few days ago my wife ,myself her sister and our daughter went to Doncaster , our return journey (incase anyone knows the road layout) consisted in coming down the road behind the market to the traffic light junction . when the lights turned green we approached onto market roundabout into the middle lane labelled A19SELBY /A638 WAKEFIELD. which as a spiral roundabout takes you over the bridge towards sprotborough etc in the left hand lane as you exit the roundabout onto the bridge. a few seconds onto the roundabout at a speed of less than 20 mph we were hit in the drivers side rear quarter panel by an articluted lorry of at least 7.5 tonne (has a forklift truck on the back ) so could have been of a heavier weight . the lorry spun the car around 90 degrees and we were fully across the front of the truck . the only thing we could see from the drivers side was the full front of the vehicle . we have no idea wewre the lorry come from ,it either come from over the bridge ,or come from wheatley hall road . the car wasn't ours it is my brothers car on loan to us from time to time on the understanding I paid for a separate insurance policy . (as he is a garage owner and has trade insurance so we wold not be covered) I did this in march (maybe earlier) and also included him on the policy as he is the owner and registered keeper as the car is usually kept at his home address. then wagon driver jumped from the cab and shouted its your fault not mine . I didn't respond at all I was in shock my 3 year old daughter was on the side that was hit . luckily the car was an audi and seemed to take the impact well , hate to think if it had been a small car like a corsa . police attended the scene made sure everyone was ok they exchange details not us and then let us go on our merry way . I took pictures of the damage to the car , the rear quarter back door , front door and front wing are all badly damaged .the rear bumper has a slight crack and the rear wheel is scuffed , im devastated and feel wholly responsible to my brother , when I phoned my insurance they stated that as my no claims was unprotected I will lose 8 years ncb if it ends up been a 50/50 split . as there unprotected policy does not consider any ncb over 5 years I wasn't even driving my wife was and Is a named driver. I have been in contact with there transport mamager who was very polite and said don't worry we will have your vehicle sorted in no time as the have a very good insurance company , he said the drivers pride was dented and he was been ribbed by his colleagues . also said if it was my car I would have throttled the guy . I know we are not to blame I know we were in the correct lane on the roundabout , but I have no idea were the lorry came from so quickly I have attached a picture of how the car ended up on the roundabout me and my brother are now in the process of assessing whether it would be better for him to fix the car , in case it goes 50/50 as the car if taken to audi for assessment would be wrote off due to the cost of fixing it. further upping an insurance premium next year as the car was valued on the policy quote at over 11k the wagon didn't seem to suffer any damage except blue paint on it from the car seems my insurance is worth nothing , and all ive had is personal injury specialists phoning me to claim for injuries , all of us eneded up with none , except it effected my sciatica , but I am due to see a neuro surgeon this week as I already have 2 slipped disks the small picture attached is from a mobile phone taken by luck from a girl who works at the public house my sister and daughter work at in scawsby.
