The passengers’ injuries are not considered life-threatening.

SA Police Inspector Michael Turnbull said police believed speed was a factor in the Hahndorf crash.

“It’s another example on a rural road, if you’re not familiar with the road and you’re going at a speed not appropriate, the chances are you’re going to lose control of the vehicle.

Mount Barker Rd residents Lucas Schiblhut, 22, and his mum Adelaide Schiblhut, 49, were among the first on the scene along with a neighbour and other drivers after hearing the crash and screams from their nearby home.

Mr Schiblhut said the crash scene was horrific with the car in the middle of the road on its roof.

“I heard it from my backyard and I started running up the road towards the crash,” he said.

“There was a lot of screaming coming from the girls and the male driver unfortunately had already died.

“But everyone was trying to help and we were trying to take the front passenger door off.”

Ms Schiblhut said it was devastating for the family of the young man who died.

“I feel for the families because all of a sudden Christmas is totally different than what it should be for them,” she said.

“It’s another loss of life.”

Major Crash investigators examined the scene overnight and police believe speed could be a factor

Mount Barker Rd was closed as Major Crash investigators investigated overnight but has since reopened.

The young man’s death is the 110th life lost on South Australian roads so far this year, compared to 66 at the same time last year.
