A Scots lorry driver who killed a mother-of-four in a horror crash has failed in a bid to overturn his prison sentence.
Ian Moorhouse, 64, pulled out from a queue of traffic and collided with Amanda Boag's Volkswagen Golf.
Moorhouse moved out at nearly 25mph to make a right turn into a side road, but his view ahead was blocked by a tractor and trailer, and he was unable to see the oncoming silver VW.
