Officers believe that the driver of a silver estate car may have witnessed a collision between a black Peugeot 207 and a white 53-seater coach, at Sutton on the Forest on Saturday 26 February 2011.
The Peugeot, which was being driven by an 18-year-old woman who was learning to drive, collided with the front offside of the coach after coming round a left-hand bend on Goose Lane, at approximately 11.10am.
The Peugeot was travelling in the direction of York, while the coach was heading in the opposite direction towards Sutton on the Forest.
The driver of the Peugeot sustained a dislocated right arm in the incident and her passenger suffered bruising to his chest. Both casualties were taken to York District Hospital for treatment and released later the same day.
The coach driver suffered minor ankle injuries which did not require hospital treatment.
Traffic Constable Neil Cholmondeley, of North Yorkshire Police’s Road Policing Group, said: “I am appealing to anyone who witnessed the collision to contact the police with any information that could help our enquiries.
“I am particularly keen to trace the driver of a silver-coloured estate car which was travelling behind the Peugeot prior to the collision. The driver of that vehicle left the scene prior to the police arriving and may hold information vital to the investigation.”
