This film came around, because we have made a cycle path around our house, and has another path that meets with it. This had for a long while resulted in crashes, because the children disagreed who should stop. So I tried to teach the children about priority to the right, stopsign and yield line. They quickly found out that a stop sign AND a yield line, would put a stop to further problems. The path which was down hill, now had priority and you could endulge in high speed cycling.
