A subsequent collision then occurred involving an Audi A6 and the rear of the Fiat.
A Ford Fiesta then collided with the central barrier.
The Nissan passenger, 12-year-old Ebony Gould from Lancaster, was taken to Royal Preston Hospital where she died of her injuries. The driver of the Nissan, a 27-year-old woman from Lancaster, suffered minor injuries.
The two occupants of the Audi, bearing Polish number plates, fled the scene .
