A Northumbria Police spokesperson said: "At about 8.10am we received a report that a number of vehicles had been involved in a collision on the southbound carriageway of the A19 near to the junction for Killingworth.
"It was reported that a number of vehicles had moved lanes to allow an ambulance to pass on blue lights.
"However, as some of the drivers have made way for the ambulance, a vehicle in the outside lane has collided with a number of vehicles.
