Sophie Louise Brine, 27, was speeding through Salisbury South on January 4, when the car she was driving hit and killed Jatinder Brar, 25, who was working as a Woolworths truck driver.

She pleaded guilty in the Adelaide Magistrates Court to an aggravated charge of death by dangerous driving and leaving an accident scene.

Today, District Court Judge Joanne Tracey sentenced Brine to seven years' jail with a non-parole period of five years and seven months.

In 2010, she was disqualified from driving after being convicted for causing death by dangerous driving after a car surfing accident in Eudunda, in South Australia's Mid North.

Judge Tracey banned Brine from driving indefinitely once released from prison, until a court order allowed her to do so.

She described Brine's decision to leave the scene of the accident as "reprehensible".

"Your offending is a very serious example of this type of offending — you were on drugs, evading police, in a stolen car and you were disqualified," she said.

"You had the previous experience of causing the death of someone known to you.

"The CCTV vision of your driving on that day would undoubtably strike fear in any other road user.

"The footage demonstrates that it was inevitable that there was going to be a collision with another car or pedestrian sooner or later."

The court previously heard the white Ford Territory involved in the fatal crash had been stolen from an address in Ferryden Park, north-west of Adelaide, sometime between December 28 and 29.

Police spotted the stolen car on Port Wakefield Road about 10 minutes before the crash, but the court heard the driver sped off in a dangerous manner and the pursuit ended.

The police prosecutor told the court a member of the public noticed the car clocking about 180 kilometres per hour shortly before hitting the truck, which hit a tree before rolling on Kings Road.

The court heard Brine did not stop, but was tracked by the police helicopter and arrested at a Taperoo property, where Brine allegedly had an imitation handgun in her handbag.

Family not ready to forgive Brine

Outside court, Mr Brar's friend Aman Dhillon said the 25-year-old's death had been "very tough" on his family, particularly his mother Kulwinder Kaur, who came from India for the sentencing.

"She says she can't forgive her because she ruined her world and this world is nothing for her now," Mr Dhillon said.

"His mother is alone in the world now," he added.

"She is crying every day now because he was calling her every day telling her how his day had been and what he had been doing and now she is not going to get any calls from him."

Today would have been Mr Brar's 27th birthday.

Mr Dhillon said the family had expected the maximum life penalty for the accounting student's death.

"Still, we respect the justice system — they did their best and hopefully she [Brine] will turn around her life and be a better person for the society when she comes back," he said.
