One man suffered head and arm injuries as a result of the crash which closed the A14 for a number of hours last night.
Medics arrived at the A14 near Kettering at 6.30pm last night (Monday), following a road traffic collision between a car and a lorry close to Junction Nine eastbound.
Four vehicles were involved in the incident near the Weetabix factory.
A man in his 40s was trapped inside one of the vehicles with head and arm injuries and was later taken to Kettering General Hospital.
Magpas medics Dr Andy Lindsay and paramedic Dan Cody, together with Dr Maria Smith, worked alongside a Northamptonshire Fire & Rescue Service crew and EMAS paramedics to remove the patient safely from the car.
The Magpas doctors and paramedic administered pain relief for the patient, before accompanying him in a land ambulance to Kettering General Hospital.
On arrival at the hospital, the man was in a stable condition.
Five patients were also assessed at the scene and taken to hospital, although none of them suffered life-threatening injuries.
Northamptonshire Police were also present, and re-opened the road shortly after 11pm after some resurfacing work due to a diesel spillage.
The Magpas team would like to thank the rest of the emergency services for their excellent team work.
