Avi,

Of course, you are correct. But there are several conditions not directly addressed within your simple definition. The easiest example: my car passed a biennial inspection last year, and I'm selling it to someone this year, even though my renewal form doesn't say anything about a smog check being required. Did my change of ownership transaction start a new cycle?

There are others, but I'll leave it at that for now.

Sincerely,
