They were on the sidewalk because the street lane they wanted to ride in was closed. That doesn't change the fact that they were on the sidewalk. They weren't pedestrians because they were riding. I don't know what local traffic laws apply to the situation. The kids should not have just ridden through the crosswalk. Nor should the driver have pulled out as kids on bikes were crossing the street. Obviously, a police accident report should have been done.
