And, I think, there are "rules" allowing these "street legal" vehicles to cross but not travel along roads with speed limits over 35. So, a street legal could cross 27/441 but not travel along it. Or, cross 466, but not travel along it.
I can't figure out why anyone would want such a vehicle, whose limitations make them really quite impractical! But, that's what makes the world go 'round!
