Dashcam footage has captured the terrifying moment a hit-and-run driver smashes into another car at speed.
Annie McGuire, an assistant editor of BBC Scotland programme The Edit, was driving on the M1 motorway near Sheffield when another vehicle rammed the back of her car.
Cameras on the front and back of her vehicle filmed the jaw-dropping incident, in which another vehicle was also almost hit.
Her children were in the car at the time, and while the vehicle was badly damaged, fortunately the driver and her passengers were unhurt.
