I think that, in general, if an officer stops you for something, you need to be able to prove your identity. If you've got a driver's license, that means you have to furnish it. But if you have just a regular state ID, you could furnish that instead. Or any other type of govt. ID, like a passport. If you have no ID and they can't verify your identity, I think they can bring you in to verify, which could be highly unpleasant, even if there are no long term reprocussions.

And seriously, a 5$ ticket? That's crazy...
