Drivers who filmed and photographed a serious accident on the M1 have been sent warning letters by police.
In June Northamptonshire Police took the unusual step of photographing people who drove past an overturned lorry and slowed down to record what was happening.
Eighty drivers have been contacted and told they were caught using their phones and cameras in this way.
