ok, but my reason behind asking that question is that here in NY, I think I have yet to see a Civic that has tinted windows (whether it has a spoiler on it or not) that does not have a section on the back window where it is not tinted for the brake light. Therefore, because I have made such observations, I asked if there was any law about it. There are many unusual laws out there, and I didn't know if this was one of them.
