A 19-year-old Quirindi woman has tragically died in a single-vehicle accident.
The vehicle then left the road and crashed into a tree, police allege.
Witnesses and police attempted to revive the woman, but she died at the scene.
A report will be prepared for the Coroner.
The local woman is one of four people to have been killed in three separate crashes during five hours on country roads in NSW on Sunday morning.
Traffic and Highway Patrol Command’s Assistant Commissioner Michael Corboy said driving on rural roads presented a different set of challenges to road users.
“The causes of these collisions are still being investigated but these tragedies should serve as a reminder of the need for road users to anticipate unexpected hazards such as animals and slowing down if you are not used to driving on dirt or gravel roads,” he said.
