Jaywalking means that a pedestrian has crossed the road NOT using the crosswalk. When there is no crosswalk, a pedestrian still needs to cross in a safe manner (not stop in the middle of the oncoming lane, etc).

All pedestrians, whether crossing legally or not have the right of way and all drivers must yield to them. Not yielding to a pedestrian in a crosswalk will get the driver ticketed.

Hope that helps a bit?
