Mexico: what its road lines look like
Mexico uses yellow between opposite directions, often as a double yellow line. White paint separates lanes going the same way.
On urban highways the yellow goes beyond the asphalt: kerbs and concrete barriers along the left side are very often painted yellow, which makes a bold stripe beside the road.
Yellow-painted barriers are especially common on city expressways and bridges.
