If a marked crosswalk has been established adjacent to a school building or school grounds, it is painted yellow if it is within 600 feet from a school building or grounds, and is known as a school crosswalk.Crosswalks should be marked at all intersections on the "suggested route to school", available from your local school. They should also be marked where there is high conflict between vehicles and students (while crossing), where students are permitted to cross between intersections, or where students could not otherwise cross.
The best safety measure for school-age children is to educate them on how and where to safely cross the street.
