Police are trying to piece together the events surrounding a serious crash on the M1 which left two people seriously injured in hospital earlier today.
Officers from the Herts, Beds and Camrbidgeshire Roads Policing Unit are appealing for witnesses to help their investigation into the collision on the M1 Southbound just after 9.40am.
The crash happened at the junction along from Hemel Hempstead, between Junction seven and Junction six just before the exit slip road to the M25 junction, when – for reasons unknown at this time – a Renault Clio in the central lane was involved in a collision with a Vauxhall Astra.
Two people have been taken to hospital with serious injuries.
Sergeant Colin Jenkinson, from the Roads Policing Unit, said: “This is an extremely serious collision which has caused serious injuries to those involved. I would urge anyone who may have seen this incident or either car prior to the collision taking place to come forward.”
The M1 was closed between Junction Seven and Junction Six southbound while police conduct an investigation and traffic is still queueing on the motorway at the time of writing.
Sgt Jenkinson urged people to avoid the area if possible.
He said: “I would ask motorists to avoid the M1 in this area and to make alternative travel plans or find an alternative route as the road is expected to be closed for some time.”
The crash comes just two days after an M1 safety awareness campaign (pictured) and amid wet driving conditions police are warning people to take extra care.
Anyone with information is asked to contact Hertfordshire Constabulary on 101 quoting ISR 175 of February 22.
