A woman was lucky to escape largely unharmed after a loose tyre smashed into her car south of Dunedin this morning.
The woman was heading south on State Highway 1 about 10.30am when the tyre, believed to be from a double axle trailer being towed, smashed into the car, hitting the windscreen at the bridge over the Waipori River.
Police at the scene praised her for maintaining control of her car despite its air bag deploying and a cracked windscreen.
She was taken by ambulance to Dunedin Hospital as a precaution, and police said she was "lucky" to have escaped serious injury.
Police were keen for the driver of the trailer, who did not stop, to come forward.
