A truck driver has been reported for dangerous driving following an eight-vehicle crash on an Adelaide highway.
Emergency services were called to Glen Osmond Road at the exit of the South Eastern Freeway about 6.30pm on Wednesday after the truck's brakes failed.
The driver did not use the road's arrester beds and crashed into seven vehicles, including a mini-bus.
Several people were treated at the scene by paramedics, and a man was taken to hospital with minor injuries. A cyclist waiting at the intersection escaped injury.
The truck driver, a 57-year-old man from Queensland, was issued with a defect notice for faulty brakes. He was also directed to have his semi-trailer inspected further.
Police from the Heavy Vehicle Enforcement Section on Thursday morning reported him for driving in a dangerous manner and failing to engage his vehicle in a low gear.
He was issued with a six-month licence suspension and will be summonsed to appear in court at a later date.
The truck crash was one of three crashes on Wednesday night.
A motorcyclist is in a critical condition after colliding with a ute on Port Wakefield Road at Globe Derby Park just before 8.30pm.
An hour later, in the small Riverland town of Bookpurnong, a 19-year-old man died when his car slammed into a tree on Bookpurnong Road.
On Thursday morning, a cyclist was flown to the Royal Adelaide Hospital with life-threatening injuries after he was discovered on the ground next to his bicycle at Gawler East.
