Fire crews were called to rescue a person trapped inside a car which overturned on the M25 this morning.
Drivers experienced long delays on the M25 after the accident, which happened just before 8am in the clockwise carriageway between J5 for Sevenoaks and J6 for Westerham.
The car towing the caravan is thought to have veered into a field and turned over, leaving the caravan behind.
One person was trapped in the car but three others were able to escape the vehicle.
The air ambulance was called to the scene, but none of the injuries are thought to be life threatening.
Three lanes of the motorway remains closed at 9am, but the road was completely re-opened by 11am.
Delays went back to J3 for the M20 at Maidstone.
