I never take any posts I read on the internet to be "fact" without some checking. That is the case with the Ca. driver's license question. According to
V.C. Section 12804.9 - Examination and Driving Test: Classifications, a class C license in Ca is a 2 wheel license, so yes if you have a class C license you can operate the Spyder...because it IS a motorcycle license, not a general Driver's license as was implied. I think the officer was correct and the Va. post is wrong, at least according to the Ca. DMV website. But what do I know??

So anyone with internet access to post the original question could have googled the DMV and gotten the exact answer he needed instead of a bunch of speculation from afar.
Good post Woodz428!
Very interesting, I read it slightly differently (but same conclusion as you), as I read it (not a lawyer, but do deal in lots of legal issues), it appears you do not need a motorcycle "endorsement" to drive a Spyder in CA. It looks like under subsection 3-D the Spyder is part of the "standard Class C license", AND motorcycles specifically excluded from the class C license by subsection 3E.
Motorcycle classification/endorsement is in addition the "C" class, called "M1" and is very clearly only for two-wheeled cycles in Section IV, again, I'm no lawyer, but to me, bringing the section and ticket to the police station, a the second ticket should get tossed. I know in AR, you have 30 days to register a new vehicle, as long as you are carrying the signed and dated Bill of Sale, the officers will not ticket for that here.
