Two men and two women have lost their lives in separate fatal car accidents across NSW on Saturday.
A Griffith man has been killed after a tragic single car crash at Barellan on Saturday morning.
The 53-year-old man was travelling toward Barellan when he collided with a number of trees, stopping near the base of the Barellan tennis racquet.
Police believe he was killed upon impact.
The circumstances of the collision are under investigation, but police suspect fatigue and speed may be contributing factors.
Further north and a crime scene has been established as police investigate following a single-vehicle fatal crash north of Molong on Saturday night.
Just before 8.30pm emergency services were called to Banjo Patterson Way, about 10 kilometres south of Yeoval, after reports a utility had veered off the road and hit a tree, causing it to roll.
The female driver and sole occupant died at the scene.
Earlier that evening, another woman died when her sedan veered off the road and hit a power pole in North St Marys in western Sydney.
Earlier that day, a 28-year-old man died after his car crashed into a tree in Mt Druitt.
