“If the trees weren’t there, they would have carried on for quite some time. It would have been a completely different result.”
The group were relatively unscathed from the ordeal, which happened last Wednesday about 1.30pm.
When firefighters got to the scene it was clear the car could still fall.
“They weren’t safe from falling until we used the winch to secure the vehicle. They calmed down a bit, but even then they were still very worried,” said Thomson.
The family were about 300m along the stock route from the Duvauchelle settlement when the car’s outer wheels went into a soft edge of the gravel road, causing it to slip 2m down a steep drop where it came to a rest against the trees.
The male driver managed to escape the car but the other four passengers remained trapped until they were freed by the fire crew using the jaws of life. The rescue took about an hour.
“They were very shaken up about it. Our job was just to keep them calm until we could get them out,” Thomson said.
“They were very, very relieved and very grateful. They couldn’t believe we were volunteers.”
Thomson said the 88-year-old managed to get herself out when a window was removed by the fire crew.
He said he supported additional signage on the stock route warning drivers about the risks of the soft edging.
GPS could cause issues by guiding motorists to the shortest routes, which might not always be the safest, Thomson said.
“What you’ve got to do is put in the shortest route excluding gravel. A lot of tourists don’t think about GPS, it will take you the shortest route no matter what the road’s like.”
Senior Constable Anita Osborne, of Akaroa, said the major factor contributing to the crash was the condition of the road edge.
She said the driver was not speeding or being careless.
Maintenance of unpaved back roads like the Duvauchelle Stock Route could push gravel to the edge, making the road look wider, Osborne said.
“The grass grows up and looks like a solid part and it isn’t. A drive-past road inspection doesn’t always pick this up.”
Christchurch City Council streets maintenance manager Steve Guy said its engineers had assessed the site and were considering what could be done to strengthen the road’s edge.
“Additional signage and sight rails are being considered,” Guy said.
Osborne said city council contractors had set up a temporary warning sign at the crash site at her request.
