The blue Renault Clio was travelling on the Plymouth-bound carriageway towards Lee Mill in heavy rain. It is thought the car skidded after hitting standing water and flipped over, landing upside down on the hard shoulder.
The accident happened just before 11am on Sunday, September 3. Nobody in the vehicle was trapped and all occupants were out of the car by the time police arrived at the scene. Officers attended to deal with the accident and clear the road.
Ambulance crews and Highways England staff were also called, with one passenger taken to hospital with suspected pelvic injuries. The other three occupants of the car were described by police as “walking wounded” - meaning they didn’t require hospital treatment.
One lane of the carriageway was closed after being blocked with debris. The lane was cleared and reopened at 1.30pm.
A police spokesman said: “The vehicle had three occupants, one person sustained injury consistent with back or neck injury.
“The vehicle may have hit standing water on the carriageway.
“One lane was blocked initially, traffic slowed in lane one into Plymouth.”
