A baby was taken to hospital following another serious crash on the A6.
The smash took place on the A6 between Finedon and Burton Latimer, the stretch which was named as a red route by road safety experts just three weeks ago, at about 8pm yesterday (Thursday).
A red Ford Ka, travelling on the A6 from Finedon towards Burton Latimer, collided with a blue Renault Scenic travelling in the opposite direction.
The driver of the Ford, an 18-year-old man from Stanwick, was taken to Walsgrave Hospital in a serious but not life-threatening condition.
The driver of the Renault, a 28-year-old woman from Burton Latimer, and a passenger, suffered minor injuries.
A police spokesman added: “A six-month-old boy, in the Renault, was taken to Birmingham Children’s Hospital, in a serious but stable condition.”
A spokesman for the air ambulance, which was called to the incident, said: “Warwickshire & Northamptonshire Air Ambulance paramedics attended in their rapid response vehicle as poor weather conditions meant that the helicopter could not fly.
“Paramedics from East Midlands Ambulance Service as well as two doctors from the East Midlands Immediate Care Scheme assessed and treated four casualties in one car, with all four being taken to Kettering General Hospital.
“Warwickshire & Northamptonshire Air Ambulance paramedics sedated the driver of the other vehicle, an 18-year-old male who was suffering from head and leg injuries.
“They then assisted with extricating him from the car and applied a leg and pelvic splint.
“One of the Air Ambulance paramedics then travelled with the casualty in a land ambulance to the major trauma centre at University Hospitals Coventry and Warwickshire, continuing treatment en route.”
Anyone who witnessed the crash is asked to call the Drivewatch Hotline on 0800 174615.
