Trucks parked on Weilers Road near the school.

Why are tractor trailers allowed to parked on the side of Weilers Rd in close proximity to the school?  This is not a once in a while thing it is all the time first it was a Yellow Tractor with box trailer and lately I have been seeing a blue tractor with a flatbead trailer.  I know these vehicles cause my daughter-in-law concern when she visits and runs early in the morning.
