Four dead on NSW roads over weekend

Four people have been killed in crashes in NSW in a weekend, leaving police fed up that drivers are still not paying attention on the roads.

The road toll stands at 14 so far this year compared with more than 30 each in January 2014 and 2015, but Traffic and Highway Command Superintendent Stuart Smith says that lower figure does nothing to satisfy police.

"Despite all of the warnings throughout the holiday period the weekend has been a dreadful one in terms of errant driver behaviour," he told reporters in Sydney.

A 62-year-old female motorcyclist died when her bike and an oncoming car collided near Orange on Friday and three hours later a 41-year-old man was killed when his car hit a tree between Forbes and Parkes.

On Saturday a 36-year-old man died when his car and a three-tonne truck collided at Lucas Heights in Sydney's south, and on Sunday a 46-year-old man was killed when two cars collided near Casino.

"I don't know what we've got to do," Supt Smith said.

"We're fed up with the behaviour."

Officers are particularly concerned with pedestrians failing to pay attention to road signals and their surroundings.

A jogger, who police are yet to identify, is fighting for his life in hospital after being struck by a car while crossing a busy street in Sydney's west on Sunday afternoon.

"What we're seeing is pedestrians crossing the road against lights, not using a crossing or motorists not giving them the requisite area to cross," he said.

A 16-year-old boy is also fighting for his life after a car he was a passenger in hit a power pole at Condell Park.

It's alleged the 17-year-old driver had been hooning and performing burnouts in the lead-up to the crash.
