A 34-year-old Adelaide man has died at the scene of a car crash on the Dukes Highway.
The man's Toyota Yaris collided head-on with a semi-trailer just north of Coomandook around 2pm on Saturday.
He was not carrying any passengers.
The truck driver was not physically injured.
Major crash investigators closed the highway for the afternoon and evening while they inspected the scene.
Eleven people died in road accidents in the Murraylands in 2019, including three on the Dukes Highway.
