cross traffic
Both lanes 4 and 5 are highlighted by using yellow lane ropes. The swimmers who compete in these lanes have either the fastest entry times or in the case of the final, the fastest qualifiying times.

A two lane roadway usually has a yellow dotted line down the center separating traffic lanes. When the line changes to a solid line, it means "No Passing". If the solid line is to the right of center then that lane has a "No Passing" restriction. When there is a double yellow line, there is "No Passing" in either direction.
