Another motorway crash is causing chaos this morning, with police and ambulance on the scene. 

One lane is closed and traffic is slow on the clockwise carriageway of the M25 between junction 16 for the M40 and junction 17 for Maple Cross. 

Traffic had to be held while the vehicles involved were moved to the hard shoulder. 

Cones have been put around a car that is still in lane four of the carriageway. 

It comes just hours after a crash on the anti-clockwise carriageway caused traffic chaos at rush hour.
