I'm free to use it as I please. If I would get a super cheap specialized veteran insurance I would only be allowed to drive it to car meets and other events, not for daily driving. Most insurance company also have a lot of regulations like that you can't drive more than 5000 km/year, it has to be in a locked garage and you have to send them pictures so they can estimate the value, some even send someone that makes an inspection of the car.
I have a regular car insurance on this Volvo and also on my 1951 Ford since I usually drive more than 5000 km/year
