A 34-year-old woman has died on the same stretch of a Wheatbelt road where a mother-of-six was killed in a fatal crash 10 days ago.
Police say the woman sustained critical injuries and died at the scene after the Kia Sorento she was a passenger in left Goomalling-Toodyay Road and rolled at about 7:20pm on Saturday.
The 34-year-old male driver and a 37-year-old female passenger were taken to hospital after suffering serious injuries.
A spokeswoman for St John Ambulance said the driver was in a critical condition on Sunday morning, while the passenger was stable.
The ABC understands the crash happened within 100 metres of where Hannah Fraser died after a car and truck collided on the same road in Wongamine, about 100km north-east of Perth.
Ms Fraser's six children, aged between one and 14-years old, were also hurt in the crash, and two of them are still in Perth Children's Hospital after they were critically injured.
The 58-year-old male driver of a cement truck that collided with the Kia Carnival Ms Fraser was driving was not seriously injured.
At the time, WA Police spokesperson said the crash was a tragic reminder of how the lives of so many can change in an instant.
"In addition to the tragic loss of life in this crash, there are six children and the driver of the truck who have all personally experienced a traumatic event and will need ongoing support," the spokesperson said.
"Incidents like this also impact on the police officers and other emergency responders who attend the scene, and who provide ongoing care to those involved."
'Gone but never forgotten'
Ms Fraser's husband, Leighton, wrote a heart-wrenching tribute to his late wife.
"I'm sure I got the chance to tell you just how much your presence in my life made me a better man or just how much you meant to me and I hope that in the years we spent side by side, my actions told you every day that I love you more than words can describe," he said.
"So as I look to our future, I vow to raise the kids to the absolute best of my ability and promise that I will always honour the amazing person you are.
"Till I see you again, rest easy my darling. I will love and cherish you always. Gone but never forgotten."
Third fatality in a month
A 41-year-old man travelling further north along the same road died on October 13.
Police say his ute left the road and rolled into a paddock in Hulongine about 8pm.
He died from his injuries at the scene.
Major crash is investigating the latest crash and is appealing for anyone with information or dash-cam vision to call Crime Stoppers on 1800 333 000.
Spate of crashes in Perth
Meanwhile in Perth, a serious crash in Hazelmere about 11.30am on Sunday caused the closure of Roe Highway southbound between Great Eastern Highway and Kalamunda Road.
Police say major crash is investigating after a motorcycle collided with the rear of a vehicle.
Main Roads WA warned drivers to seek an alternative route if possible due to heavy traffic.
The Great Eastern Highway bypass was also closed eastbound from Stirling Crescent to Roe Highway in Hazelmere.
A woman in her 80s suffered serious injuries in a separate incident nearby at the intersection of Roe Highway and the Great Eastern Bypass in Forrestfield about 9.15am, when an object fell from the rear tray of a Nissan Navara ute.
A police spokeswoman said a Mitsubishi ASX travelling behind the Nissan had taken "evasive action" to avoid the object and as a result, a Toyota Corolla collided with the Mitsubishi.
