A 4-year-old boy was saved by his child seat and restraints when the car he was in and a full milk tanker collided on State Highway 1 near Palmerston.
The boy was extremely lucky to survive the crash yesterday with just a cut to his knee, Senior Constable Stefan Witehira said.
"The 4-year-old was in a child seat and restrained and I would, without a doubt, say that has saved him from serious injury or worse," he said.
The boy's 25-year-old father was next to him in the back seat of the car, which was driven by the man's 54-year-old mother. His 65-year-old father was the front seat passenger.
All were wearing seatbelts.
