I would suggest the school to most probably move the play area from there to a safer place as the playground is much closer to the road and its not at all safe for kids to place near a place where fast moving vehicles move around..i would give the examples of kids/students injuries by playing near a road.

We convience  our school authority by telling that children are not  having playground they do not have a place to play, they are unfreedom less as a result they are playing close to the road this causes accidents to the children thats why we can convience them to arrange the  playground  in our school as a result the children should be safe and happy to play.
