A South Australian woman who killed her two-year-old granddaughter in a car crash caused by five seconds of inattention has been spared an immediate prison term.
Sentencing the 64-year-old in the District Court on Friday, Judge Liesl Chapman said to send her to jail would only prolong the family's suffering and grief.
"No good at all would come from you being jailed for what happened," the judge said.
"It would only compound the tragedy, if that is possible.
"No penalty handed down by this court will ever be as harsh as the punishment you are inflicting upon yourself every day."
The crash, in July last year, occurred when the woman had momentarily taken her eyes off the road to find a music track on her phone that her grandchildren liked.
The phone had been mounted on the air conditioning vent at the time with the music being streamed through the car's sound system.
In the space of about five seconds, her car crashed into the back of a parked truck which had run out of fuel on the Sturt Highway, north of Adelaide.
Her two granddaughters were in the car at the time with the younger girl killed and her six-year-old sister injured.
Judge Chapman said the woman was devastated by what had happened and has since been diagnosed with post-traumatic stress disorder.
She said the accident emphasised the need for continuing education and reminders to everyone about the dangers of inattention, even momentary inattention, while driving.
"Like many of us, you were acting with the best intent and will in the world, that is to please the children in your care, to find music that you knew they loved to hear, and to make the journey fun and enjoyable for them," the judge said.
"It is a tragic reminder to us all of the dangers of up to just five seconds of inattention on the road."
Judge Chapman imposed an 18-month jail sentence, but suspended the term, placing the accused on a one-year good-behaviour bond.
The woman, whose identity cannot be revealed, was also disqualified from driving for 10 years.
