'The road ain't a bin': Vigilante biker throws rubbish back into car

A vigilante motorbike rider in New Zealand has shamed a driver who threw rubbish out of his car window.

The biker filmed as he drove up to the red 4x4, which was parked at a set of red traffic lights, and picked up the rubbish before chucking it back inside the vehicle.

The car's shocked driver could do little more than mutter a short apology as the motorcyclist berated him for littering, the Daily Mail reports.

In the footage, filmed in New Zealand, the rider bends down to pick up the blue piece of paper and tosses it back through the driver's side window of the 4x4.

"Use a rubbish bin, mate," he tells the dumbfounded motorist.

"Sorry mate," he replies.

The rider adds that "the road ain't a rubbish bin" before roaring off up the road.

The biker posted the video online and said he had been waiting for an opportunity to shame a littering driver.

"I've always wanted to do this, and today I just happened to have my camera rolling at the right time," he said.

The footage was filmed in April 2014 but recently resurfaced online.
