Elderly NSW driver's car left dangling

An elderly woman has driven her car through a third-storey barrier of a carpark in Sydney's south.

Emergency services were called to a Cronulla council carpark on Wednesday afternoon where they found the vehicle hanging over Croydon St.

The woman managed to get herself out of the car, a NSW Fire & Rescue spokesman said.

A pedestrian in her late teens was treated for shock and the elderly driver was taken to hospital with upper body pain, an ambulance spokesman said.
