By now, you’ll be aware of the value of the dashcams in working out who was at fault in a crash. But you’ll see few clearer illustrations than this.

This fella was minding his own business when he collided with a minivan running a red light. He posted the video on Youtube himself, writing in the description: “As soon as she crossed the white line I realise she’s not going to stop. I brake and turn trying to avoid her and instinctively honk my horn.”

But the crash couldn’t be avoided. The police were quickly on the scene, and questioned both drivers. The minivan driver claimed she wasn’t at fault, but a quick look at the footage showed she clearly was.
