The vehicle ended up entangled in a tree and a power pole, which plunged hundreds of homes into darkness for more than 12 hours.
The Toyota Land Cruiser ended up severely damaged and overturned on its side when the driver reportedly lost control on Southern River Road in Gosnells shortly after midnight.
Locals heard the crash and called emergency services.
“[I] came out, called Triple Zero straight away, a couple of neighbours came out to see what was going on,” resident Manu Nebe told 9News.
The vehicle mounted the median strip, taking out a power pole, which left more than 200 residents in the dark for much of the day.
Police say a 24-year-old man was behind the wheel and with him was a 25-year-old woman.
Residents rushed to help the pair trapped inside.
They say the woman was crying and screaming for help, with one neighbour staying beside her and keeping her calm until emergency services arrived.
They’re both in intensive care at Royal Perth Hospital.
Police are now investigating how the car got in this position.
