Four young people are in hospital with serious injuries after two separate serious crashes in WA over the weekend.
A 21-year-old man of Sorrento and a 22-year-old woman of Watermans were seriously injured after a crash on Reid Highway in Carine overnight.
At around 10.40pm, the 21-year old-man was the driver of a Toyota Landcruiser driving west along Reid Highway.
At the intersection of Marmion Avenue, it collided with a Peugeot Hatch being driven by a 20-year-old woman of Scarborough.
The Landcruiser then hit a walk barrier and traffic control light pole, before rolling.
Both occupants of the Landcruiser had to be cut from the vehicle, and were taken to Royal Perth Hospital. The driver of the Peugeot was not hurt.
Major Crash officers are also investigating a crash at Geraldton yesterday afternoon which left a 23-year-old woman from Sunset Beach and a 23-year-old man of Waggrakine with serious injuries.
At around 3.45pm the two were the rear passengers in a Holden Commodore sedan being driven by a 18-year-old man of Bluff Point.
As the car travelled on to Edward Road from Arthur Road, it is believed that the rear tyre blew, with the Commodore losing control and rolling several times in a nearby paddock.
This car was travelling in company with a Holden Commodore ute, and police will investigate whether the Commodore sedan was recklessly driving prior to the crash.
Both injured passengers were taken to RPH where they are being treated for head injuries.
Anyone who witnessed either is asked to call Crime Stoppers on 1800 333 000.
