If you are waiting to cross the street, you should not cross if the light is yellow. The light is about to turn red, and cars will enter the intersection. If you are in the street, finish crossing the street. If you have not started crossing the street, stay on the curb. This sign means you are coming to a crosswalk.
Crosswalks are two white lines painted on the road which go across the street.
You should walk inside the lines. Cars, bicycles and in-line skates must stop to allow people in the crosswalk to cross the street. When you use the crosswalk to cross the street, before you step into the street, you should look carefully to the left, right and left again to be sure it is safe to cross. This sign means you are near a crosswalk by a school. On school days this area will be busy when school is opening and closing .
