A LORRY driver who killed a fellow motorist moments after falling asleep at the wheel has been jailed for four years.

Ian Thorburn, 53, did not pull over after his truck collided with Robert MacLellan, 65, on the A92 dual carriage way near Cowdenbeath, Fife, in May 2014.

The High Court in Edinburgh heard how stunned drivers gave chase to Thorburn after he continued on his way. Thorburn failed to brake or give any impression that he would pull over.

Passing sentence, judge Lady Wise told Thorburn that if he had not pleaded guilty at the earliest chance, she would have sentenced him to six years. She banned Thorburn from driving for 10 years and told him that he would have to resit his driving test at the end of his ban.
