A driver was taken to hospital with life-threatening injuries after a three-car accident near Redbourn yesterday.
The incident happened on the M1 southbound carriageway between Junction 10 for Luton airport and Junction 9 for Redbourn just before 6.30pm.
Three vehicles were reportedly involved - a white BMW, a silver Vauxhall Astra, which was broken down on the hard shoulder at the time and a lorry, which did not stop at the scene.
Police are keen for anyone with any information or dash cam footage to come forward.
