They are also supposed to ride in single line on busy streets and to walk bicycles across the busy intersections（交叉路口）．(2)By following these rules, bicycle riders will stay healthy be safe.
In one recent year, the National Safety Council reported that 34 thousand bicycle riders were hurt in highway accidents. In the same year,another six hundred riders were killed.

They are wearing helmets and paying closer attention to cycling rules.
