A man has been taken to Whanganui Hospital after his car rolled on Kaikokopu Rd in Whanganui on Wednesday afternoon.
The man was the sole occupant of the vehicle which was headed in the direction of Aramoho and near Blueskin Rd when it crashed.
Constable Zak Thornton was at the scene and said that it appeared the driver had lost concentration.
No other vehicles were involved.
"If you move about 20 metres in front of the car you can see the gravel has changed a little bit, he has gone up the bank there and then rolled to where he is," Thornton said.
