Diagram of an example intersection of two-way streets as seen from above. The East-West street has left turn lanes from both directions, but the North-South street does not have left turn lanes at this intersection. The East-West street traffic lights also have green left turn arrows showing when unhindered left turns can be made. Some possible markings for crosswalks are shown as examples.
