A woman has survived a terrifying road rage ordeal in which her car was rammed twice by a four-wheel-drive vehicle, nearly tipping it on to its side.
The incident happened in Johns Rd about 7.45pm on Tuesday.
The woman was driving a green Nissan south in Johns Rd, near the roundabout at Sawyers Arms Rd, and slowed to 60kmh to pass through roadworks, Senior Constable John Moore said.
"The driver had travelled around 500 metres past the roundabout when a white four-wheel-drive vehicle which had been following her appeared to accelerate and rammed into the rear of her car," he said.
"The driver reports that she braked and skidded as her wheels locked up. The four-wheel-drive appears to have backed off a little but then accelerated again, hitting her car hard for a second time.
"The impact caused the Nissan to drift sideways and on to the side of the road. The car tipped over, but fortunately landed back on its wheels without rolling over."
The woman's car stopped about 300m north of McLeans Island Rd, opposite The Press printing plant.
The 4WD left the scene without slowing. It may have turned right into McLeans Island Rd.
"The driver was not hurt but was very shaken by the incident, which appeared to be totally unprovoked," Moore said.
"The only thing the driver has done was to slow down - correctly - for roadworks.
"This incident could easily have resulted in serious injuries to the victim and to other road users.
"We are appealing for any help to identify the offending vehicle and its occupants."
Police believe there were two people in the 4WD. The driver is described as a clean-shaven male European in his 20s, while the passenger is described as a female European, of similar age, with long blonde hair.
Investigators have spoken to the driver of the Nissan and to another witness, but are appealing for more information.
"We know there were other witnesses and we would like to hear from them as soon as possible,'' Moore said.
"We are also seeking help from anyone who can help identify the white four-wheel-drive vehicle or its occupants."
Anyone with information is asked to call Moore on 363 7336 or the Christchurch police on 363 7400.
