When I was looking, State farm told me that they could make exceptions for current policy owners. But they did not want just my EV.
My farmers agent tried to get the "office" to do it. He even asked me to send a copy of the policy after I got it with someone else, so that he could show them and make a case, but no go.
I ended up with Progressive for the EV. They ask if it is capable of of 45 or above. I assume that they also mean the plate registration status as well. Mine ended up being registered as 45 and below. There was no mention of this when I signed up for the plates, but when I renewed that is what it said. You gotta love the gov't. I don't have the ambition to fight about this one. If I had to re-do my EV plates, I would save the several hours of my life and just get regular plates. (time really is money, or in this case money gets time time)
