Major Crash investigators examined the intersection and seized the truck and trailer, which have been towed for forensic testing and mechanical inspection.

The driver, a 23‑year‑old Mount Torrens man, is assisting detectives.

The intersection was shut down for hours as police investigated the scene, with roads reopening just after 1.30pm.

The man’s death marks the 69th life lost on South Australian roads this year.
