A car that lost control and hit a concrete power pole and a fence in Okoia is not the first to crash on that stretch of road, a resident says.
Whanganui Fire senior station officer Bryce Coneybeer said the car looked to have lost control on No.2 Line and slammed backwards into the pole, then forwards into the fence.
The callout came about 11.15pm.
"They were okay, they were walking," he said.
Mr Coneybeer thought there were two occupants in the car, but they did not have to be cut out.
The road had to be closed as the scene was dangerous, with wires hanging down.
Powerco confirmed 4000 customers lost power about 11pm when the car hit the pole.
Power was cut to Taupo Quay and Durie Hill areas, Powerco network operations manager Phil Marsh said.
All supply was restored by 5.35am.
An Okoia resident, who said the car was still "embedded" in her neighbour's fence on Friday morning, said the stretch of road was particularly bad for crashes.
She said they had three crashes in the area in as many months.
The woman said something needed to be done to stop cars speeding on No.2 Line.
She said her eyesight was good, but some cars went by so fast she couldn't tell what colour they were.
