It actually could be regarded as a criminal offense, but more likely a civil-infraction; like most traffic stuff. I would consult a local lawyer ASAP. A criminal offense is a bitch for many reasons, obvious and not so obvious.
That said, it looks like they have their bases covered.
I don't do the tinyurl thing, so take out the six stars broken by a space (***** *****) in the following urls:
