Baldock gym teacher Chloë Ward, 22, needed plastic surgery after the shunt between Junction 9 and 8 at about 6.55am on Friday, April 29, sent her red Vauxhall Corsa crashing through a fence and into some trees.

Letchworth scaffolders Craig Dean, Gerry Fuller and Neil Stewart helped her from the wreckage moments before it went up in flames.

Police investigating the crash have released a photo of a large white van with the words ‘Steve Beeby’ written on the sides and back in hope of tracing its driver.

PC Philip Watts, who is investigating, said: “I believe the driver of this van stopped on the hard shoulder immediately after the accident and may have witnessed what happened.

“I would also like to speak to the driver of a silver Vauxhall Astra estate with a 53 registration number plate, which was travelling southbound at the time of collision and continued on past Junction 8 for Coreys Mill, Stevenage.

“I am appealing for both of these drivers to come forward as I believe they may have seen what happened and could help with our investigation.”

Anyone with information should call PC Watts on 101.
