ONE lane of the westbound A40 has closed after a car left the carriageway at about 4pm.

The road is partially closed between the Headington and Cutteslowe roundabout after a silver Vauxhall Corsa left the road.

The only occupant, a woman who police said they did not know the age of, is being treated for minor injuries.

Police said the road should be fully open again by 5.15pm.
