A DRIVER and his passenger are in a critical condition in hospital after their car collided with another vehicle, crossed a dual carriageway and hit a tree in a busy town centre.

The 67-year-old male driver and 63-year-old female passenger, both from Hatfield, were seriously injured after their blue Ford Fiesta collided with a silver Ford Focus on Lytton Way at the junction with Six Hills Way, Stevenage, at around 4.20pm yesterday (Sunday).

The Fiesta continued over the roundabout, across the central reservation of the dual carriageway and down an embankment where it collided with a tree.

Paramedics rushed the driver to Lister Hospital with life-threatening injuries, while the seriously injured woman was taken to Addenbrooke’s Hospital in Cambridge.

A doctor was flown to the scene in the Cambridgeshire police helicopter.

The driver of the Ford Focus was uninjured.

Road closures were in place while the emergency services dealt with the aftermath of the crash.

Police are appealing for witnesses to the crash to come forward.

Investigating officer, Pc Samantha Sparkes from the Bedfordshire and Hertfordshire road policing unit, said: “This is a busy stretch of road in the town centre and I am appealing to anyone who was in the area at the time and saw the collision to contact police at the earliest opportunity via the non-emergency number, 0845 3300 222.”
