TRAFFIC is being diverted southbound of the A1(M) after a serious five-car smash.

Motorists are being redirected off the motorway at junction six, Welwyn, and are allowed back on at junction four, for the Oldings Roundabout.

A man in his 40s was airlifted to the Royal London Hospital with life-threatening injuries following the crash at 8.35am today (Tuesday).

The cars involved in the smash were a silver Smart car, a blue Renault Twingo, a blue Vauxhall Corsa, a silver Mercedes C200 and a white Ford Transit van.

East of England Ambulance Service spokesman Gary Sanderson attended the collision between junctions five, at WGC, and four, for the Oldings Roundabout.

He said: "When our paramedics arrived, they found a man who was in a critical condition.

"He was being cared for by an off-duty London Ambulance Service paramedic who was on his way home and stopped to help.

"The man was treated and stabilised extensively at the roadside before being airlifted to hospital."

Gary added: "I would like to pass on my thanks to the off-duty paramedic and district nurse who stopped to help on behalf of the ambulance service.

"Their help was very much appreciated.
