Harey,  the hare-brained rabbit, and his friends go riding their cycles, but he does not obey the highway code. He has to be persuaded to wear his safety helmet after he has fallen off his bike and banged his head. He then rides out of the drive onto the road without looking where he is going, rides on the pavement and fails to stop at red traffic lights where he knocks down Pillow the parrot on the pelican crossing.
