A health and safety expert was too ill too drive when he blacked out at the wheel and smashed into a bright A-Level student's car, a High Court judge has ruled. Peter Haynes will have to pay substantial damages to 19-year-old Simon Green, who was left with a permanent brain injury after the horror crash on the A11 in Norfolk. Mr Haynes, 56, told London's High Court he was not to blame because he was in a state of 'automatism', similar to sleepwalking, after abdominal pain caused him to pass out.
