An appeal for witnesses has been launched today (Tuesday) following a motorway crash which has left an 18-year-old woman in hospital.

Officers from the Roads Policing Unit are appealing for witnesses and information after a car collided with the central reservation on the northbound carriageway of the A1(M).

The crash, involving a silver Volkswagen Polo, occurred at around 12.45pm on Saturday between junctions 7 and 8 for Stevenage.

After colliding with the central reservation for reasons unknown at this time, the car then hit a tree before coming to a stop on the hard shoulder.

The driver of the car, also an 18-year-old woman, was left with cuts and bruises.
