A pedestrian, believed to be a man, has been killed as he walked on the hard-shoulder of the M25 in Surrey after being hit by a lorry.
Reports suggest the man in his 50s got out of his car after stopping in a motorway lane without the lights on, before walking along the hard-shoulder.
A lorry is then believed to have hit the stationary car and pedestrian around 4.30 am.
The motorway was closed clockwise between junctions six at Godstone and seven at Redhill but has now re-opened.
Surrey Police say the pedestrian, who has not been named, was pronounced dead around 5.00 am.
The other occupant of the car who was in the vehicle during the accident was treated for minor injuries.
A diversion has been put in place but motorists are advised to expect significant delays.
Officers continue to appeal for witnesses.
