A motorist's dash cam captures the terrifying moment a driver rams into another vehicle not once, but twice, in a stunning act recklessness on the busy A38 in Plymouth, on Sunday.
The video shows how a black Seat cuts into frame and proceeds to sideswipe the white Ford, driving in the middle lane. The driver of the Ford pulls over to the side of the road, but is then rammed a further two times.
Police announced that they arrested a 21-year-old man from Plymouth, on suspicion of driving while unfit, possession of a knife and criminal damage.
Officers say he remains in custody.
