CCTV footage captures coach flipping over on motorway

If you needed a reminder to buckle up when travelling in a coach, this is it. Shocking footage from inside a coach in China shows the moment dozens of passengers flew around inside the vehicle, after an impact caused it to flip off the road.

At the beginning of the video, it's possible to see a car overtaking the coach through the driver's window. For unknown reasons, it suddenly swerves into the side of the vehicle.
