Witness Kate Blockley said the crash occurred when the 18-year-old driver failed to negotiate a turn at the intersection of Sandpiper Loop and Cormorant Way just before 10am.
At first Ms Blockley thought the car had pulled into a driveway.
‘I didn’t even think that anything had happened and as I went to turn right I noticed the car was into the fence so I pulled over,’ she said.
‘They were all fine when they first got out of the car. The kids were a bit panicked because she (the driver) was panicking but once she settled down the kids were fine.’
Resident David Ika said it was fortunate the car did not cause more damage to his home.
‘It sounded like a gun shot,’ he said.
‘I went outside and it was just a car crash.
‘There was no screeching so it’s weird; I don’t know how it happened.’
The crash was the second to occur in the suburb in two days.
Western Power’s head of field operations, Brad Lacey, said emergency response crews attended a crash the previous day when a car hit a power pole on Yangebup Road.
‘Our network response crew’s first priority was to make the area safe before they repaired the damaged pole and safely restored power to 193 customers shortly after 9pm,’ he said.
Tuesday’s crash was also the second car versus house in Yangebup in the past few months.
In July a family and occupants of a car were lucky to escape serious injury when a car crashed into a Yangebup Road home just after lunchtime on July 28.
