A car overturned trapping the driver and injuring her legs.
The ambulance service responded to a 999 call that a driver was trapped in her car on Cockersand Drive, Lancaster.
By the time fire engines and crews from Lancaster had arrived at the scene, the 20-year-old driver was out of her car. She was taken to Royal Preston Hospital with leg injuries.
Firefighters used a winch to haul the car back onto its wheels and prevent further fuel spillage onto the road surface.
