EMERGENCY services were called after a vehicle lost control on an icy road and overturned in Harefield.
The accident happened at 7.45am today (Wednesday) in Breakspear Road North, and all three emergency sevices attended.
Two people were treated for shock by paramedics but it was not thought they sustained any serious injuries.
Several roads have been closed off, including Gilbert Road, Tyle Lane, and one end of Harefield High Street, forcing buses to divert their routes.
The vehicle was a red Vauxhall Astra, and council teams have attended the scene to clear debris and grit the roads.
Malcolm Brown, a witness at the scene said: "The road was a sheet of ice, the red car was on its side, it looked a bad accident."
