Earlier on Saturday, a 23-year-old woman became the fourth person to die at the weekend when her car hit a tree in the NSW Riverina.
Emergency services were called to the crash on Goldfields Way in Old Junee where the woman had died at the scene.
In a separate incident, a 24-year-old male driver was charged over a fatal multi-vehicle crash at Ermington in north west Sydney.
Emergency workers were called to the three-car collision at River Rd shortly after 11.30pm on Friday.
The man and his two female passengers, aged 28 and 25, were taken to Westmead Hospital, but the younger passenger later died from her injuries.
The crash also left a female ute driver with minor injuries, while two people in the third car appeared to be unhurt.
The male driver was taken to Granville police station after being released from hospital, where he was charged with numerous offences including dangerous driving causing death and dangerous driving causing grievous bodily harm.
Earlier on Friday, about 8pm, a male pedestrian was killed when he was hit by a car in Canley Vale, in Sydney’s south-west.
He died at the scene while the driver, a 64-year-old woman, was taken to Liverpool Hospital for mandatory testing.
On the Mid North Coast, a 57-year-old motorcyclist died at the scene in Forster after a collision with a ute about 10.30am on Friday.
Traffic and Highway Patrol Commander Assistant Commissioner Michael Corboy said that even one life lost on our roads is one too many, especially when they could be prevented.
“It is important that every driver, or rider, takes responsibility to ensure that safety is their number one priority when they are behind the wheel, or on their bike,” Assistant Commissioner Michael Corboy said.
“Please slow down, wear your seatbelt, avoid handling mobile telephones, make certain you are adequately rested before driving, and take regular breaks to avoid fatigue.”
