In your example, you seem to single out a single person, guilty of (perhaps) multiple infractions. Is this the case? If so, how many handicap parking spots are there? Are the rest legally being used?
If you have approached this person and explained your circumstances, and they still don't understand, you are right to escalate the matter. It appears the school president (principal), has taken some action, although ineffective. It may be possible that this person doesn't read those newsletters, as they appear to be out of touch with their surroundings.
That said, what would YOU suggest the school president do? Why don't you offer them al alternative solution? While they appear sympathetic to your needs, short of physically monitoring the parking spots for offenders, what else can they do? One of you--yourself or the school president--must appeal to this idiot's senses. Is there any type of security at the school...could they monitor the situation?
If nothing else works, perhaps your local law enforcement could look into it, though I don't know how aggressive they could be with parking enforcement on (what sounds like) private property.
Good luck to you.
The sidewalk “closer” to the school is where this parent should have parked - but he didn’t - this is like the 20th parent who has done this - I’ve said stuff to almost all of them - or the principal has...I confronted this parent this morning and explained to him the law...what the reg’s are on this - and his response was I’m waiting for my daughter...well - wait for for her in an open space or by the sidewalk where every one else parks in the morning to drop off their kid - there are 2 spaces - that’s it...my son is the only disabled child that attends this institution - and the other disabled parents - grandparents - that use these spots as well..it’s just not one parent - but lots of them...it’s more about bringing in tuition to a private Catholic school competing with a major consolidated public school system - so let’s dump on the disabled in lieu of not offending parents of children without disabilities...because we need them to attend and the $$$ they bring in...I think that’s just wrong!
