Historical plates any cop problems ?

Insurance and tagging is two completely different things. I have historic tags on my 5a and Dart but have regular car issuance. So from a tag prospective I should only have the cars on the road for "special occasions". But from an insurance prospective I can drive them all day everyday.

I see your point. Unfortunately, here in BC a branch of the provincial government handles both insurance and registration (tagging). I would be surprised if it isn't a condition of your insurance though that the vehicle is tagged appropriately.
