The real trick is actually enforcement. Nobody obeys the rules because none of the rules are enforced. So sure, make the law that prohibits just certain vehicles from doing a right on red. 100% guarantee you that the drivers of those cars will not obey the new rule and 100% guarantee you that cops won't enforce it.

I wish they would just make the licensing requirement stricter for driving these behemoth vehicles. But this would have to happen on a state by state basis..
