Police have had to tell a father of four, who was walking to get petrol for his broken-down car, that his partner and eldest child had been killed when a truck crashed into the car he left on the side of the road.
The car, which was towing a trailer, ran out of fuel around midnight on Sunday and the 27-year-old male driver was walking the 28 kilometres to Corrigin to get petrol.
Police said a semi-trailer towing grain trailers came around the bend of the road and crashed into the rear of the car and trailer, pushing them into a nearby paddock.
The 26-year-old mother and her 10-year-old son died at the scene.

Her other three children, two sons aged 5 and 8, and a three-year-old girl, suffered injuries and were taken by helicopter to the Perth Children’s Hospital.
They were in a serious but stable condition on Monday morning.
The 46-year-old driver of the semi-trailer alerted authorities to the emergency before police later spotted the father of the children walking along the Brookton-Corrigin Road around 11km west of the Wheatbelt town.
Road closures in the area remain in place and major crash investigators are at the scene.
