A zebra crossing is a type of pedestrian crossing used in many places around the world. Its distinguishing feature is alternating dark and light stripes on the road surface, resembling the coat of a zebra. A zebra crossing typically gives priority to rights of way to pedestrians.The crossing is characterised by longitudinal stripes on the road, parallel to the flow of the traffic, alternately a light colour and a dark one. The similarity of these markings to those of a zebra give the crossing’s name. The light colour is usually white and the dark colour may be painted – in which case black is typical – or left unpainted if the road surface itself is dark. The stripes are typically 40 to 60 centimeters (16 inches to 2 feet) wide. In countries such as the United Kingdom, zebra markings give pedestrians permanent right of way if accompanied by a belisha beacon or conditional right of way when accompanied by traffic lights. In other countries they are also used on pedestrian crossings controlled by traffic signals, and pedestrians have priority only when the lights show green to pedestrians.
