A driver died in the collision involving three HGVs on the M6 near Knutsford, Cheshire, on July 8.
On Friday, North West Motorway Police tweeted a photograph of a notice of intended prosecution letter and a photograph of a postbox as it said 48 motorists would soon be notified of the offence.
The post read: “On the 8th July our @CheshireRCU for the North West Motorway Police Group were dealing with a Fatal Collision on the M6 Southbound.
“To the 48 People seen/witnessed videoing the incident from their hand held mobile phones on the Northbound Carriageway whilst passing the incident, your details have now been provided to us and a letter of prosecution is in the post to you.
“It is an offence to use a hand held mobile phone whilst driving.
“Furthermore it is insensitive to video the scene of such a devastating incident where by family, colleagues, friends may well not be aware of the incident. #BeRespectfulalways
#RoadSafety #Fatal4 #BeKind.”
Three other people received what were believed to be minor injuries in the collision on the southbound carriageway between junction 20, Lymm Interchange and junction 19, Knutsford shortly before 12.40pm.
