The woman, who is in her 40s, was driving her blue 2007 plate Ford Fiesta on the A14 eastbound at Stow-cum-Quy, towards Newmarket, at about 6.20pm when she was involved in a collision with a lorry which was parked up in a lay-by. Sergeant Simon Goldsmith, from the Beds, Cambs and Herts Road Policing Unit, said: We are keen to speak with any motorists who were on that stretch of road around the time of the collision in order to help us establish the series of events. I am particularly keen to identify the driver of a lorry who we believe pulled out of the lay-by just moments before the collision. There was also a lorry parked up which was carrying two tractors. Anyone with information is asked to contact the Road Policing Unit by calling 101 and quoting incident 357 of October 29.
