Two 14-year-old girls in a stolen car reached speeds of 100km/h before crashing head-on into another vehicle on Wednesday night.
The pair and the woman they hit luckily escaped serious injury - but only because the offending driver and the oncoming victim braked heavily moments before the crash.
The crash happened on Hills Rd, Shirley, Christchurch, about 10.10pm.
Less than a minute earlier police had tried to stop the car at traffic lights in Shirley Rd. They had been alerted of a Honda Logo being driven erratically with no lights on in Richmond.
Police located the vehicle and tried to get it to pull over without success.
