With Historic plates it is the word primary that allows you to drive a lot more than what DMV will tell you. Primary use is 51% and if you sign up for a few parades or even frequent some parking lot car shows, you have a good case, if anyone questions you. It's the daily driver that will have an issue with the Historic plates and the usage for them. Like others have stated previously, just about anytime I drive my truck it is going to or from an exhibition, as I rarely will have a day I drive that people are not walking around the truck and asking questions, and I only have a small deuce and a half.
