EMERGENCY services had to cut free a 19-year-old man, who was trapped for two hours, from his car after it crashed into a tree.
The accident happened early yesterday morning on the Kamilaroi Highway west of Gunnedah.
The car left the highway and rolled into a tree, before part of the tree fell onto the car.
The man suffered serious lower-leg fractures and was treated at the scene by ambulance paramedics before he was freed from the wreckage. He was airlifted to Tamworth hospital in a stable condition.
Meanwhile, a Karara woman was lucky to escape serious injury when her vehicle rolled near Tambar Springs on Saturday night.
The 20-year-old was driving along Black Stump Way when she swerved to miss a kangaroo that had hopped onto the road.
Police say the woman missed the kangaroo but over-corrected before striking a concrete culvert on the other side of the road.
The vehicle rolled a number of times as a result, causing extensive damage.
The woman was able to get herself out of the wreckage and call a relative for help before police and ambulance were contacted.
She was taken to Gunnedah hospital with minor injuries.
A police spokesman said officers were reminding motorists of the danger of animals straying onto locals roads during dusk and dawn.
Police say drivers should try to avoid instinctive reflexes to swerve, and instead should brake in a straight line, to avoid any collisions with oncoming traffic or leaving the road.
