‘Rubber-necking’ drivers who filmed and photographed a motorway crash while at the wheel are facing prosecution.

Four people were injured after a car crashed into the back of an ambulance that was attending another incident on the M40 on Saturday.

Photographs and videos emerged from the scene as passing motorists captured the unfolding incident on camera while driving, which is illegal and carries £100 fine and three licence points.

And police say they have now issued Notices of Intended Prosecution to a number of motorists who they know to have committed an offence.

Chief Inspector Parsons, from Thanes Valley Police’s Roads Policing unit, took to Twitter to warn culprits of their fate.

He said: “For those drivers filming the M40 crash j2 to 3 we will be in touch."

And on Monday, he added: “Last job of the day completed-NIPs sent to those drivers filming M40 crash (whilst driving) on Saturday evening.”

South Central Ambulance said they were called to reports of a road traffic incident on the northbound carriageway near junction 2 at 3.25pm and while at the scene, a car collided with the stationary ambulance.

Two people, one of the ambulance crew and a female patient, were in the back of the ambulance at the time of the collision.

Four ambulance crews and two officers were then sent to the scene and an off-duty member of staff assisted.

Two females, one in their thirties and another in her forties were treated by paramedics and taken to John Radcliffe Hospital with potentially serious but not life-threatening injuries.

Two men, one in his fifties and one in his twenties were treated by crews and then taken to Wexham Park Hospital with non life threatening injuries.

Police have not yet confirmed how many drivers face action over using their mobile phones during the incident.

It comes after Essex police issued NIPs to more than 40 drivers seen photographing and filming a crash on the M25 near Thurrock last week.
