This is the shocking moment a seemingly out-of-control car smashed into a stationary vehicle after it suddenly came to a halt on the A40.
Dashcam footage from a following lorry shows traffic moving along the busy roadway. All of a sudden, the cars in front of the lorry come to a halt as another vehicle attempts to join the A40 from a slip road.
The lorry jams its brakes on, which seems to cause the car following the truck to swerve to avoid crashing into it. However, the driver seemingly fails to see the stationary line of cars in front of the lorry, and crashes into the last vehicle.
According to the truck driver, the woman in the back of the car that was crashed into was treated in hospital for shock-like symptoms.
