The shocking photographs have been released as part of a hard-hitting anti-drink-driving campaign. Dad-of-three Trevor McCabe, 52, was three times over the limit when he was driving his son along the B122, near Castleford, North Yorkshire, in August this year.
Mr McCabe's Volkswagen Golf smashed head-on into a Honda CRV. The dad died and left his little boy seriously injured. The police photographs show the terrible aftermath of the crash.
It was so severe that Mr McCabe's Golf was flipped onto its side.
The driver and a passenger in the Honda - which was travelling in the opposite direction - suffered what were described as '"serious, life-changing injuries".
"Apart from the physical trauma, we can only imagine what this child is going to remember for the rest of his life, after being in that car while his dad died next to him."
"On the day this happened Mr McCabe was irresponsible and selfish, thinking only of himself. He had no consideration for his actions as he continued to drink before he drove
"It is a simple thing that we ask - don't drink and drive - if not for yourself, think of what effect it can and does have on others.
