The drink-drive campaign this Christmas will target young people as figures show that this year, drivers aged between 20 and 24 failed more breath tests than any other group.
Dean Wilson's 21-year-old son, Matthew, was killed two years ago after crashing his car into a tree.
He and his daughter Hannah have been raising awareness of drink-driving, and the family has agreed to illustrate the risks with Matthew's wrecked car.
