Four hurt as car rolls onto M11 junction in Essex
Two women, aged 64 and 33, were seriously injured when their car overturned on a slip road from the M25 and rolled onto the M11 in Essex.
Two men were also injured in the crash on Saturday afternoon.
The four people, who were in a Honda Civic that ended up on the southbound M11, were initially cared for by a number of motorists.
The 64-year-old woman was airlifted to Royal London Hospital and the 33-year-old went to Queen's Hospital, Romford.
Police have appealed for witnesses to the crash and said three doctors, two off-duty police officers, a first aider and a retired paramedic helped the injured before ambulance crews arrived.
The two men, aged 35 and 30, were taken to Queen's Hospital. All four occupants of the car came from Leicester.
Investigating officer Pc Alan Lamb said: "The car had turned off the clockwise M25 and was negotiating a bend on the slip road to the M11 when it overturned and came to rest in one of the London-bound lanes of the M11."
