Four lorries, a coach and four cars have collided on the M11 in Essex, closing a stretch of the motorway.
The crash happened on the northbound carriageway, between junctions eight and nine, near Stansted Airport.
Two people trapped in the coach and one person trapped in a car have now been released and are with the ambulance service.
The northbound carriageway is closed and only the hard shoulder is open on the southbound carriageway.
Emergency services were called shortly before 1000 BST.
Police said they expected the road to be closed for several hours.
