A lorry driver remains in a critical condition following a multi-vehicle crash on the A14 eastbound in Bury St Edmunds.
Suffolk Police were called at 3.05pm to the incident at junction 44 (Moreton Hall exit) involving seven vehicles including three cars, three HGVs and a van.
A spokesman for the East of England Ambulance Service said two ambulances, two ambulance officers and a rapid response vehicle and hazardous area response team are at the scene.
The westbound carriageway was initially closed to allow the air ambulance to land.
The driver of one of the lorries - a man aged in his 40s - was treated at the scene for serious leg and pelvis injuries and airlifted to Addenbrooke’s Hospital.
The eastbound carriageway re-opened just before 10pm.
At least five drivers are likely to receive a summons after being seen filming from passing vehicles.
Police are warning motorists that not being in proper control of their vehicle could lead to further collisions – and those caught using devices to film while driving are likely to receive a summons in the post.
The incident also caused major traffic problems in the centre of Bury St Edmunds.
Anyone who saw the collision is asked to call Suffolk Police on 101, quoting CAD number 230 of Wednesday, April 20.
