The driver of a car transporter which overturned on the A2 at Pepper Hill, Northfleet, has been released from hospital.
The man, who is in his 30s and from Ramsgate, suffered serious but not life-threatening injuries during the accident which saw at least six vehicles, believed to be Hyundais, coming off the lorry and strewn across both London and coastbound carriageways.
The truck driver was taken to a hospital in London, while a second motorist suffered minor injuries but was released from Darent Valley Hospital the same day.
Police are still appealing for witnesses to the smash, which led to long delays and queues of traffic stretching back several miles in both directions.
PC Paul Soesan of the Roads Policing Unit thanked those who have already contacted them following the accident on January 15.
He said: "We have spoken to a number of witnesses who have supplied information, but there might be other people who could help with our investigation."
Police can be contacted by calling 101 and quoting reference 15-814.
