Illinois Central School Bus

I live near the Caseyville Il location in a 20mph Disabled child zone. I have a 5 yr old son with severe Autism who is a huge flight risk and knows nothing about dangerous situations. These school bus drivers speed thru this zone regularly even though I have kindly asked them not to do so several times.The street I live on is also a No thru traffic zone and there is no children to be picked up on this street. The lack of compassion and understanding I have recieved from Illinois Central bus co. Has just been unbelievably rude.
