The penguins who obey the highway code in Antarctica

The antics of the birds are captured in this hilarious video

Not every commuter follows the rules of the road but these penguins filmed in Antarctica are setting a fine example.

Dozens of the birds meticulously follow intersecting 'roads' - pathways made by previous penguins.

As each penguin waddles towards the intersection the fascinating birds only have two choices - right or left.

One penguin spends more time than the rest pondering his route, causing a traffic jam to form behind him.

The reason for the penguins' adherence to the highway code is revealed at the end.

One penguin steps off the road - only to be punished with a slip on ice.

The movements of the penguins were shot in Antarctica by Melissa Brennan, a student from Arizona.
