Red Light District

I noticed the most ridiculous sign on my way to work today. It said "No right on red when children are present." WTF? Is a right on red like pornographic material or something? I would really like someone to tell me what exactly this sign prohibits.

1st of all, does that mean if I have a kid in my car, I can't make a right on red? Or if the guy next to me has a kid in his car? Or if there is a schoolbus behind me? How close do the children have to be? If there is a kid asleep in his bed in the house on the corner, am I guilty? Is this a strict liability sign, or would I have to know about the child? Of course, it says "children" so maybe if only one child is "present" I'm safe. But I also wonder what qualifies as a child? Minors? Does that mean a 17 year old can never make a right on red at that corner, because he will be a child who is present? Well, maybe since it says children and not child, he could make the turn as long as he was alone - but if his girlfriend is in the car then he's in trouble! What a ridiculous sign! Obviously, I know the point is that they don't want you making a right on red when kids are standing there waiting for the bus, or walking to school, or whatever. But seriously, does nobody think about enforcement issues when the make these rules? A sign indicating certain times of the day would be better - those kinds of signs, by the way, are all over the place. Honestly, it made me want to make a right on red in the hopes that I would get a ticket, just so I could point out how stupid the damn sign is.
