Driver shows the importance of a dashcam after woman rolls back into his truck

A driver in the US has shown off exactly why dashcams are such useful devices, after it proved he was not to blame for a minor incident at a set of traffic lights. The driver, named only as 'TheBeardDontLie' on YouTube, uploaded the footage after a woman rolled backwards into his truck at a set of traffic lights – and then attempted to blame it on him.

The video shows the man's truck pulling behind a small silver saloon car at a set of traffic lights, as both vehicles wait to turn left. Captions pinpoint the moment the woman let off her brakes and began rolling backwards.
