A man who killed a couple when his lorry toppled on to their car as he read a text message has been jailed for five years and three months.Ethen Roberts' vehicle crushed Mark and Tamsie McHale's Audi on the M62 in West Yorkshire, in 2012.
Leeds Crown Court heard he had received a message less than two minutes before he hit the car, causing his lorry to jack-knife and topple over.
Roberts, 44, of Immingham, admitted causing death by dangerous driving.
When investigators analysed Roberts' phone they discovered he had received a message from a friend one minute and 16 seconds before his lorry veered into the couple's car.
'Superb teacher' They later found he had sent and received almost 100 messages to and from the same friend in the three days leading up to the smash - all when the lorry's tachograph showed the vehicle was being driven.
Mr McHale, 46, and his 43-year-old wife, from Bishop Auckland, County Durham, had been travelling west on the M62, between junction 26 for Chain Bar and junction 25 at Brighouse, before the crash.
Hair and beauty salon owner Mr McHale and his wife, a deputy head teacher at Gilesgate Primary School, in County Durham, died at the scene, on 25 July.
Colleagues of Mrs McHale described her as having been an "absolutely fantastic person" and a "superb teacher".
Roberts, of Ings Lane, Immingham, North East Lincolnshire, pleaded guilty to two counts of causing death by dangerous driving.
