I'm not sure if there is a law, but are dirt bikes prohibited in suburban communities or are they allowed to be on the street like a motorcycle? There are some younger people in my area that ride all around the neighborhood, but only they ride through grassy areas such as people's private property. I'm pretty positive once they cross onto someone's land that they can get in trouble. I don't think they should be allowed to ride freely because they end up tearing up people's yards.
