Two people have died and another is in critical condition after a major accident involving a B-Double truck and an ute in the far north of Adelaide.

The crash occurred on Saturday around 12:15 p.m. on the Stuart Highway between Pimba and Glendambo.

The 23-year-old male driver of the Ute from the ACT and a 57-year-old woman from Para Vista, who was a passenger in the truck, were pronounced dead at the scene.

Parts of the Stuart Highway between Pimba and Coober Pedy remain closed to all traffic in both directions as the road surface was destroyed by the fiery crash.

Major crash investigators are currently on the scene trying to determine the circumstances of the terrible accident.

Traffic heading north on the Stuart Highway will be diverted at Pimba and vehicles traveling south towards Adelaide will be diverted at Coober Pedy.

Repairing the road is expected to take months.

Later on Saturday, an ute rolled around on private property in Lindley, South Africa’s riverside, and a 26-year-old man died on the scene.

Three other people in the car were hospitalized with minor injuries.

“Three people have already lost their lives on our streets during this long weekend, and the police begged all road users to be careful, especially in regional areas, and not to take unnecessary risks,” the SA police said in a statement.

“In the past five years, six people have been killed on South Australian roads on the long weekend in March, five of them on regional or country roads.”

The death brings the death toll on South Australian roads to 20 this year.

In the twelve months to January 2021, there were 1,120 road fatalities in Australia.
