Drive cautiously when pedestrians are near and may cross your path. They are probably the most vulnerable road users and have to be treated carefully regardless of who has the right of way. When you cross the intersection always yield to a pedestrian.
As a pedestrian you should always use good judgment and not interrupt the flow of traffic. Pedestrians are not permitted on any toll bridge or highway crossing unless there is a sidewalk with signs stating that pedestrians are permitted to use it. Crossing the street in the wrong place is called jaywalking. It is extremely dangerous. Many jurisdictions prohibit jaywalking, and you could be cited.
