Actually, there are nine TBD states. This fact, and your comment for that matter, have nothing to do with the price of tea in China.

There is. Frequently, the person cited is directed to "nominate" the actual driver if not them. This is regardless of the fact that they have no legal obligation to do so. If you don't like that option as the defendant, you can point out the identity confusion to the law enforcement agency and the citing officer MAY ask the court in writing to dismiss but is not required to do so. In one case I'm familiar with in Oxnard, CA, the defendant (obviously 30 years older than the driver in the photo) showed up for trial and the citing officer immediately told him he could leave as the citation would not be prosecuted. This was AFTER the defendant called the police department and informed the citing officer of the incorrect driver identity. I wonder what would have happened if the defendant didn't show up.
